| 摘 要： | 采空区的塌陷、涌水等地质灾害因素给煤矿正常采掘带来极大的安全隐患，也严重威胁煤矿设备及其人员的安全。大倾斜煤层采空区的勘查解释较倾斜、缓倾斜煤层采空区的勘查解释复杂。通过正演模拟验证了可控源音频大地电磁测深法探测大倾斜煤层采空区的可行性，结合可控源音频大地电磁测深法在贵州六盘水某煤矿和遵义某煤矿大倾斜煤层进行采空区勘查，从理论和实例验证了该方法在大倾角煤层采空区勘探中的可行性和有效性。

| 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. |
