  • Hydraulic anchor drill truck: The prospects of coal mine anchor drill RIGS in China
    Hydraulic anchor drill truck: The prospects of coal mine anchor drill RIGS in China There are over 3,000 tunneling faces in state-owned coal mines alone every year. The construction of anchor bolt support requires a considerable number of anchor bolt drilling machines. The market demand has led many research and manufacturing units to invest in the development and production of anchor bolt drilling machines and their supporting equipment. There are various product types, and similar products keep emerging and being repeatedly tested. The anchor drill rig is an objective need for the development of anchor support technology. It is bound to move forward according to certain laws. After a period of competition, it will gradually get on the right track. After analyzing domestic and foreign anchor drill RIGS, it is believed that the development trend of coal mine anchor drill RIGS will have the following characteristics: (1) As coal mine anchor support will be widely applied in large quantities of coal roadways and semi-coal rock roadways, for a considerable period of time, single anchor drill RIGS will be the mainstream of anchor drill rig product development. In some roadways where integrated tunnel boring machines are used, hydraulic single-unit anchor drilling RIGS will gradually be adopted, and the hydraulic power source of the tunnel boring machines will be shared. To further enhance the mechanization level of anchor bolt support for comprehensive excavation equipment, we will continue to explore how to widely utilize airborne anchor bolt drills. Airborne anchor drill RIGS still mainly use hydraulic rotary drilling methods, but they will still seek reasonable drilling methods to solve the problem of drilling rocks with high compressive strength and strong abrasiveness. In large-section rock tunnel excavation, the use of hydraulic drilling vehicles will further demonstrate their superiority in drilling anchor bolt holes and installing anchor bolts, while the application of dedicated anchor bolt drilling vehicles will not be put on the agenda in the short term. (2) Hydraulic rotary anchor drill RIGS will develop in the direction of further increasing output torque to meet the needs of high-speed drilling of anchor holes and installation of anchor rods. The hydraulic anchor drill rig will not only further improve its technical performance but also enhance its reliability, with a focus on addressing the durability of hydraulic components and the long-term stability of underground operation. It will also seek ways to share power sources with existing underground equipment. To broaden the application scope of hydraulic anchor bolt hole drilling, people will explore the issue of high-torque rotation combined with low-energy impact anchor bolt hole drilling. (3) The pneumatic anchor drill rig has good torque-speed characteristics, is lightweight and has a large stall torque. However, the reliability of the product and the stability of product quality will attract more attention for a period of time. In order to use pneumatic anchor drill RIGS more widely, coal mine sites will consciously adjust the compressed air system and gradually pay attention to the application of mobile air compressors underground. (4) Electric anchor drill RIGS have low costs, simple main engine power and low energy consumption. People will continue to make efforts to improve the reliability of electric anchor drill RIGS and reasonably solve the problem of outrigger methods. Given the problems of hard torque characteristics and poor motor reliability of electric anchor drill RIGS, when using pressure water to flush anchor holes, the key to motor reliability will lie in overload capacity and waterproof and sealing performance. Only after the two issues are fundamentally resolved can electric anchor drill RIGS be more widely used in underground operations. (5) The pneumatic impact type anchor bolt hole drill is used in conjunction with the pneumatic rotary anchor bolt drill and the pneumatic rotary drill (side anchor bolt hole drill), making the underground power system single and achieving good results. People will further improve the pneumatic impact rock drilling method to better match the pneumatic rotary drilling method. (6) The drilling tools used in rotary drilling for anchor bolt holes are consumable and vulnerable parts with large consumption. With the normalization of anchor drill rig products, the performance and quality of drilling tools will be given more attention. The structure, materials and processing techniques of drilling tools will gradually become more reasonable, and the application range of rotary drilling methods will be expanded. (7) The further development of anchor drill RIGS requires a further improvement in the standardization level of anchor drill RIGS and their supporting equipment. In this technology, product competition will mainly lie in quality, service and price. For this reason, some manufacturers of anchor drill RIGS and drilling tools will make efforts in scientific management and gradually and consciously implement the ISO 9000 series standards to make their products more competitive. (8) The research on the performance parameters of anchor drill RIGS is the foundation for the product development and quality control of anchor drill RIGS. The competition among several products will gradually enhance the recognition of the importance of fundamental research on anchor drill RIGS. In the competition of anchor drill rig products, manufacturers will compete for technology, talent and the construction of conditions. (9) The development of anchor drill RIGS has certain technical difficulties, and its application effect is related to the on-site usage and maintenance conditions. The coal mine site will seek to apply scientific management methods for anchor drill RIGS, attach importance to and strengthen the maintenance and upkeep of anchor drill RIGS, and establish maintenance points for anchor drill RIGS. (10) The level and quality of anchor drill RIGS affect the comprehensive benefits of anchor support. On-site coal mines will gradually pay attention to the comprehensive economic benefits of using anchor drill RIGS and drilling tools, and take it as an important basis for choosing anchor drill RIGS and drilling tools.   Tag

  • Maintenance and management issues of hydraulic coal mine anchor drill RIGS
    Maintenance and management issues of hydraulic coal mine anchor drill RIGS   In general, the selection of hydraulic system oil should meet the following requirements: It must not contain steam, air or other impurities that are prone to vaporization or vaporization. It has excellent lubricating performance and a very high liquid film strength. Has a high degree of chemical stability; Appropriate viscosity and good viscosity-temperature performance. For drilling rig hydraulic oil, it iS recommended to use Lanchou or Shangchou hydraulic oil (200 40n1m ² /iS). In cases where the source is difficult, 30 # mechanical oil can be used in summer and 20# mechanical oil in winter. The hazards and preventive measures of oil contamination in hydraulic systems Hydraulic system contamination is a major cause of hydraulic failures. Contaminants mixed into the system will accelerate the wear, abrasion, burning and even damage of hydraulic parts, or cause valve malfunction or noise. Contaminants can clog the throttle holes or throttling gaps of hydraulic components, alter the working performance of the hydraulic system, cause malfunction or even complete failure, and lead to misoperation and accidents. Dust particles in the hydraulic cylinder will accelerate the damage of seals, scratch the inner surface of the cylinder barrel, increase leakage, cause insufficient thrust or unstable operation, crawling, reduced speed, and produce abnormal sounds and vibrations. It may also cause the filter screen to clog, making it difficult for the hydraulic pump to draw in oil, resulting in poor oil return and causing cavitation, vibration and noise. When the clogging is severe, the filter screen will be punctured due to excessive resistance, completely losing its filtering function and creating a vicious cycle in the hydraulic system. Therefore, it is necessary to strengthen management, prevent oil contamination, and ensure the safe and reliable operation of the hydraulic system. (1) The hazards of oil contamination to the hydraulic system: blocking the fit clearances between the relatively moving parts of hydraulic components such as pumps and valves, blocking the throttle holes, damping holes and valve ports in hydraulic components, and preventing the components from working normally; When dirt enters the fit clearance between the relatively moving parts of hydraulic components, it will scratch the mating surfaces, damage the accuracy and surface roughness of the mating surfaces, accelerate wear, increase component leakage, and sometimes cause the valve core to get stuck, resulting in component failure. Excessive dirt in the oil causes the oil pump to suck oil: (1) The oil filter screen at the suction point is clogged, resulting in excessive suction resistance, which makes the oil pump unable to work normally, generating noise and vibration; The dirt in the oil will cause it to deteriorate. When water mixes into the oil, it will cause the oil to emulsify, reduce its lubricating performance, increase its acid value, shorten the service life of components and increase leakage. (2) Measures to prevent oil contamination. Among the common faults in hydraulic systems, many are caused by unclean oil. Therefore, keeping the oil clean is an important aspect of maintaining hydraulic equipment. The measures to prevent oil contamination are as follows: The area around the oil tank should be kept clean and the oil tank should be covered and sealed. The oil in the fuel tank should be replaced regularly. Generally, the oil should be changed after a cumulative operation of 1,000 hours. When oiling, it should pass through a filter with a mesh size of 120 or more. Regularly inspect and clean the filter; Regularly clean the hydraulic components with kerosene and unblock the pipelines. Regularly inspect the pipe joints and sealing devices between pipelines and components. 3. Hazards of Air Entering Hydraulic Systems and Preventive Measures: The oil used in hydraulic systems has very low compressibility, but the compressibility of low-pressure air is very high, approximately 10,000 times that of the oil. Even if there is a small amount of air in the system, its impact is significant and can cause system malfunctions. (1) Hazards of air entering the hydraulic system. The air dissolved in the hydraulic fluid will escape from the oil when the pressure is low, causing noise in the hydraulic system and creating bubbles and cavitation. When reaching the high-pressure area, under the impact of the pressure oil, the bubble skin is shattered, causing a sharp increase in pressure and generating noise in the system. When the vaporization in the oil is rapidly compressed, it releases a large amount of heat, causing local overheating and damaging the hydraulic components and hydraulic oil. The air in the oil is highly compressible, causing the working components to crawl and vibrate, thus disrupting the smoothness of operation. A large number of air bubbles mixed in the oil will deteriorate the oil, reduce its service life and accelerate the wear of components. (2) Measures to prevent air from entering the hydraulic system. Depending on the different reasons for air entering the hydraulic system, the following points should be noted during use and maintenance: Regularly check the oil level in the oil tank to ensure there is sufficient oil in the tank. 4: Maintain from the appearance, such as whether the joints are loose, whether there is oil leakage, and whether there are cracks in the pipeline, etc. Before starting the pump, check whether the oil is added as required and whether the oil temperature is normal. When the temperature is below 10℃, it should be operated without load for more than 20 minutes (especially in winter). Pump start-up and post-start-up inspection: When starting the pump, it should be started in a start-stop manner to raise the oil temperature and ensure the smooth operation of the driving device before entering normal use. After the pump starts, it is also necessary to check whether there are any adverse phenomena such as cavitation, overheating and bubbles.

  • What is the working principle of the anchor bolt drilling vehicle? How does it enhance geological stability?
    Anchor bolt drilling vehicles are commonly used mechanical equipment in modern mines, tunnels and underground engineering. They are mainly used for geological reinforcement, support and enhancing the stability of underground structures. In high-risk environments such as mining and tunnel construction, anchor drill trucks play a crucial role. This article will delve into the working principle of the anchor bolt drilling vehicle and analyze how it enhances geological stability through effective anchor bolt support technology. I. Overview of Anchor Bolt Drilling Vehicle The anchor drill truck is a kind of mechanical equipment specifically designed for drilling operations, mainly applied in the support construction of tunnels, mines and underground projects. It integrates multiple functions such as drilling, grouting and anchor bolt installation, and is capable of achieving effective and accurate operations. The anchor bolt drilling vehicle drills holes in the rock layer through drilling equipment, then installs the anchor bolts into the holes and consolidates the anchor bolts through grouting, thereby providing the necessary geological reinforcement and support. Ii. Working Principle of Anchor Bolt Drilling Vehicle The working process of an anchor bolt drilling vehicle usually includes the following steps: drilling, anchor bolt installation, grouting reinforcement and anchor bolt tensioning. The specific steps are as follows: 1. Drilling The anchor drill truck first drills holes in rocks or soil layers through its powerful drilling device. During the rotation of the drill bit, the drilling car provides sufficient torque and power through the drive system to ensure that the drilling depth and diameter meet the design requirements. During the drilling process, the positioning system of the drilling vehicle ensures the accuracy of the hole position and avoids the deviation of the drilling. The depth and Angle of the borehole are determined based on the actual engineering requirements and geological conditions. The diameter and depth of the borehole may vary in different geological environments. The accuracy of drilling directly affects the installation effect of the subsequent anchor rods. Therefore, when drilling, it is necessary to ensure the stability of the drilling vehicle equipment and the sharpness of the drill bit. 2. Anchor bolt installation After the drilling is completed, the anchor bolt drilling vehicle will push the anchor bolt into the hole. Anchor rods are usually made of steel bars or high-strength alloy steel, featuring excellent tensile strength and bending resistance, and can effectively form a firm connection with the surrounding rocks or soil layers. Anchor bolt installation is divided into two types: Static anchor bolts: This type of anchor bolt is usually inserted into the borehole by the mechanical arm of the anchor bolt drilling vehicle, and the front end of the anchor bolt is fixed in the hole. The reinforcement principle of static anchor rods mainly relies on the frictional force between the anchor rods and the surrounding rock strata to provide support. Dynamic anchor rods: Dynamic anchor rods are generally fixed by high-pressure air flow or grouting methods. They can generate a stronger bonding force between the anchor rods and the rock strata through the effect of dynamic pressure. The installation process of anchor rods requires the equipment to accurately control the insertion depth, Angle and position of the anchor rods to ensure the reinforcement effect.   3. Grouting reinforcement After the anchor rods are installed, the anchor rod drilling vehicle still needs to carry out grouting operations, injecting slurry to firmly bond the anchor rods with the surrounding rock layers. The materials used for grouting are usually cement slurry or high-strength chemical slurry. After being injected into the holes, these slurries will solidify and form a solid cementing layer. Grouting not only enhances the bonding force between anchor rods and rocks, but also further reinforces the surrounding soil or rock layers, improving geological conditions. During the grouting process, the drilling rig can accurately control the grouting volume, pressure and grouting time to ensure the best grouting effect. 4. Anchor bolt tensioning After the grouting has solidified, in order to increase the tensile force of the anchor rods, the anchor rod drilling vehicle will also tensify the already installed anchor rods. Through mechanical tensioning devices, anchor rods can further generate a tight tensile force with the rock layer, thereby enhancing the supporting force. This process is particularly important for geological stability, especially in weak or loose rock strata, where the tension of anchor rods can significantly enhance the geological support capacity. Iii. How can anchor bolt drilling vehicles enhance geological stability The anchor bolt drilling vehicle plays a significant role in improving geological stability through its effective drilling, installation and reinforcement functions. Specifically, the anchor bolt drilling vehicle enhances geological stability in the following aspects: 1. Improve the supporting force of the rock strata structure The stability of rock strata is usually influenced by a variety of factors, such as stress, temperature changes, and hydrological conditions. Especially during the process of mine exploitation or tunnel construction, changes in the external environment may cause the sliding or collapse of rock strata. The anchor bolt drilling vehicle can effectively improve the supporting force of rock strata through drilling and anchor bolt support. Anchor rods form a strong physical connection with rock strata through anchoring technology, significantly enhancing the stability of the rock strata and preventing deformation or collapse of the rock strata caused by external stress. 2. Prevent geological disasters Geological disasters, such as rockbursts, earthquakes or ground subsidence, usually have a serious impact on underground projects. The anchor bolt support of the anchor bolt drilling vehicle can not only enhance the anti-deformation capacity of the rock layer, but also provide additional support force when geological disasters occur, avoiding the occurrence of disasters or reducing their impact. By effectively reinforcing rock strata, anchor drill vehicles can significantly reduce the risk of geological disasters and ensure the safety of underground projects such as mines and tunnels. 3. Enhance the stability of the working face At construction sites such as tunnels and mines, the working face is often affected by unstable geological factors, making it prone to problems such as rock strata falling off and collapsing. Through accurate support design and construction, the anchor bolt drilling vehicle can form a stable support structure at the working face, ensuring the safety of construction personnel. The reinforcing effect of anchor rods enables the rock strata to evenly bear external pressure, thereby avoiding cracking or deformation caused by excessive compressive stress in local areas. 4. Enhance the shear resistance of soil or rock strata The anchor bolt drilling vehicle significantly enhances the shear resistance of soil or rock layers by reinforcing them. Especially in weak geological environments, traditional support measures may not be able to provide sufficient shear resistance. However, the anchor bolt drilling vehicle can make the rock layer more stable when subjected to external shear force through the tensile force of the anchor bolt and the consolidation effect of grouting. The main function of anchor bolts is to disperse the external shear force into a larger area of rock strata around, thereby reducing stress concentration at a single location and enhancing overall stability. 5. Enhance the bearing capacity of underground structures such as mines and tunnels In complex underground projects, the application of anchor bolt drilling vehicles can significantly enhance the load-bearing capacity of underground structures. Especially in relatively loose or weak rock strata, anchor rods, through their fixing and reinforcing functions, can effectively enhance the underground structure's capacity to bear external loads and reduce geological accidents caused by excessive loads. Iv. Application Prospects of Anchor Drill Vehicles With the continuous development of underground engineering, the technology of anchor bolt drilling vehicles is also constantly innovating and improving. Modern anchor drill trucks are not only limited to traditional mining operations but are also widely used in tunnel construction, subway construction, large-scale underground projects, and dam reinforcement, among other fields. With the introduction of intelligent technology, future anchor bolt drilling vehicles will be able to achieve more effective and accurate operations, while enhancing operational safety and construction efficiency. Conclusion As a multi-functional and effective mechanical equipment, the anchor drill truck plays a crucial role in underground engineering, mining and tunnel construction. Through operations such as drilling, anchor bolt installation, grouting and tensioning, the anchor bolt drilling vehicle can effectively enhance geological stability and prevent the occurrence of rock layer collapse, sliding and other geological disasters. With the continuous advancement of technology, anchor drill trucks will play a more significant role in enhancing the safety of underground projects, improving production efficiency and reducing the accident rate.
