Abstract:Taking the goaf of No.5 lower seam in the east wing of Yushuling Coal Mine as the engineering background for cumulation water prevention and control,the technology of compound prospecting and directional exploration was proposed.The composite exploration technology in underground water cumulation area includes three stages,macroscopic geophysical exploration,mesoscopic drilling exploration and microcosmic exploration.It also involves in long distance directional drilling precision exploration and drainage engineering scheme,covering long distance directional drilling equipment technology and borehole layout design.The implementation effect of the project was monitored and evaluated to drainage the goaf water and solve the hidden water hazard caused during working face mining and layout.According to the engineering practice,during the 6 months implementing the technology of composite prospecting and directional exploration,about 226000 m3 goaf water was drained,the water pressure decreased from 1.42 MPa to 0.9 MPa,and the water discharge effect was favorable.
