Abstract:The mined-out areas will not only bring great hidden dangers to normal mining of coal mines, but also seriously threaten the safety of coal mine equipment and its personnel. The exploration and interpretation of large inclined coal layers in mined-out areas is more complex than that in inclined and gently inclined coal layers. Through forward simulation, the feasibility of CSAMT method in detecting the mined-out aeras of large acute inclined coal layers has been verified. Combining with controllable source audio geodesymetry, exploration in a large inclined coal layers in coal mines in Liupanshui and Zunyi has been carried out. It will verify the feasibility and effectiveness of the method in the exploration of large inclination coal layers in mined-out areas theoretically and practically.
