when opening the hole, the first with small impact work, propulsion force and low speed drilling, in order to facilitate the needle positioning,(need to dust, give the appropriate water to reduce dust) when the needle drilling 10 cm or so, and then with the full throttle impact, and appropriately increase the propulsion force, improve the speed,(need to dust the gas water mixture to maintain the appropriate proportion), normal rock drilling work, drill a drill The rod should stop the operation o

What is the working principle and stress analysis of grooved drill pipe Grooved drill pipes are still widely used in the coal mining industry, because a lot of excavation and exploration are required, so the requirements for drill pipes are high. Today, the editor will tell you about the working principle and stress analysis of grooved drill pipe? Grooved drill pipe The grooved drill pipe is a spiral transport groove set on the surface layer of the drill pipe. Under the premise that it does n

What are the precautions for the use of geological auger pipes Auger pipe is still used more frequently in excavation projects, and it is also relatively easy to use. It exists and is used in many projects. Today, Xiaobian will tell you about the use of geological auger pipes. What are the precautions? Auger Rod 1. When using the first drilling and excavation, it is necessary to "grind new buttons" first, which includes applying the technical innovation of screw oil first, and then using the

What should be paid attention to when the grooved drill pipe is applied The grooved drill pipe adopts the product structure design of double helical structure or multi-head helical type with large pitch and small compound lead, which improves the drilling and slag removal characteristics of the drill pipe. It is widely used in many engineering projects, and it is also the choice of many professional technicians. Today, the editor will tell you what to pay attention to when applying grooved dril

Auger Rod 1. The geological auger pipe is based on the high torque performance of the geological drill pipe. It adopts single helical blade or double helical structure blade, and is made by electric welding and welding through the coiling process of prestressed steel strand. 2. The drill pipe body is made of geological alloy pipe, and the drill pipe joint is made of alloy structural steel, which has been quenched and tempered in a vacuum environment to further improve the fatigue resistance li

What are the types of directional drilling in coal mines? The underground directional drilling technology of coal mines provides effective technical means for underground coal mine gas drainage, water hazard prevention, and exploration of hidden disaster-causing geological factors. Real-time measurement and control of borehole trajectory is a key technology for directional drilling in coal mines. Measurement while drilling system and screw motor are the core equipment to realize real-time measu

Hydraulic propulsion mechanical hole-making full-hydraulic crawler drilling rig products are mainly used in the field of mining engineering. The main technical indicator is hydraulic machine hole-making at the bottom of the hole. The quality level is in a leading position in China.
