Purpose and scope of use
The fully hydraulic tunnel drilling rig for coal mines is mainly used for drilling gas pumping (discharge) holes, grouting fire prevention holes, coal seam water injection holes, anti-burst pressure relief holes, and water exploration holes in coal mines. , geological exploration holes and other engineering drilling holes. It can be used for drilling various coal and rock formations with rock solidity coefficient. With the appropriate configuration of drill bits, drill pipes and other drilling tools, engineering operations such as coring and drilling of soft coal seams can also be carried out.
Main technical features
Power head fully hydraulic combined drilling rig. The split volume timber structure facilitates underground transportation, shifting and installation.
, Unique hydraulic system, dual pumps, hydraulic chuck, and hydraulic holder to clamp and unload the drill pipe, which is safe, convenient and labor-saving.
The drilling rig consists of a hydraulic pump station, power head, frame, operating table, column support and other components. It is connected with high-pressure oil pipes during operation and is operated away from the wellhead for safety.
The design of the hydraulic system is mature, simple, reliable, easy to master, and easy to analyze and solve when a failure occurs.
, double column or four column support, multiple holes can be drilled in one anchorage, light weight, high efficiency and strong applicability.
