Introduction du produit This series of underground drilling rigs is mainly used for drilling operations at various angles in underground coal mines, including water detection & drainage, gas detection & drainage, dust prevention water injection holes, various engineering holes and geological structure detection holes. The rig adopts mechanical transmission and hydraulic feed design, featuring a simple structure, compact size, and easy operation and maintenance. This crawler-mounted drilling rig is upgraded and developed on the basis of the original underground drilling rig. It is equipped with a crawler traveling mechanism to realize autonomous movement, and can easily travel and operate even in narrow roadways. The crawler chassis is equipped with four hydraulic props on the basis of the original support legs, providing better stability and higher safety. In addition, a hydraulic chuck is installed to realize automatic loading and unloading of drill rods, making the operation simpler and safer for workers, and the drilling more efficient and labor-saving. It has enhanced power output and stronger performance, capable of drilling in various geological formations including coal seams, coal-rock mixed strata and rock strata. Application Scope

•  Mining Application: Suitable for water detection, coal seam detection, gas drainage and dust prevention water injection at various angles in underground coal mines.
• Engineering Application: Suitable for construction of grouting holes, wiring holes, pile integrity test holes and core sampling holes in projects including subways, airports, highways, high-speed rail engineering, building reinforcement and ground surveys.
