摘要
首次将地震CT技术应用于综放顶煤工作面的构造及结构面探测。通过采探对比分析,证明地震CT探测综放面内隐伏断层线性成像明显,结果与实际比较吻合,工作面内煤层增厚区及裂隙发育区也有显现。地震CT探测技术的广泛应用将为保障综放面的高产高效提供一条有效途径。
Seismic tomgraphy is applied in exploring the cryptostructure and fracture of longwall top-coal caving face in exploration and mining, it is proved that the blind faults have evident linear image of seismic tomography, which is in good correspondence with the practice. The area of thickened coal seam also is shown in the image of seismic tomography. Wide application of seismic tomography in coal industry is one of effective ways to ensure high productivity and high efficiency of longwall top-coal caving face.
