2013年8月22日,在内蒙古黄玉川煤矿,由中国地质科学院勘探探技术研究所(勘探所)研制的SDC-1500型车载深水井钻机成功应用于我国首个采用集束式气动潜孔锤反井施工工艺的矿山排水井施工。该井位于内蒙古黄玉川煤矿主井西30m左右的位置,钻井直径700mm,钻深340m,主要用于临时通风、排水和紧急情况下的快速救援通道。在钻进过程中,充分发挥全液压动力头钻机动力头可90度抬头上钻杆,上扣转速、扭矩可无级调节、反打钻
On August 22, 2013, the SDC-1500 vehicle-mounted deep well drilling rig developed by the Institute of Prospecting and Geotechnical Engineering, Chinese Academy of Geological Sciences at the Huangyuchuan Coal Mine in Inner Mongolia was successfully used in China for the first time to adopt a beam-type pneumatic downhole hammer Well Construction Technology of Mine Drainage Well Construction. The well is located about 30m west of the main shaft of the Huangyuchuan Coal Mine in Inner Mongolia with a drilling diameter of 700mm and a drilling depth of 340m. It is mainly used for temporary ventilation, drainage and emergency rescue tunnels. In the drilling process, give full play to full hydraulic power head rig power head can be 90 degrees on the rise of the drill pipe, buckle speed, torque can be adjusted steplessly, anti drill
