Abstract: In order to meet the needs of safe and efficient tunneling in coal mine, ZDY2-1000LF (T) drilling rig for water exploration and drainage has been developed. The design idea, structure and hydraulic system of drilling rig were introduced. The test shows that the structure design of the drilling rig is reasonable and the technical indexes of each test meet the requirements of design and industry standards, which can improve the construction efficiency of hole for water exploration and drainage in coal mine roadway heading face.
