To use 3D seismic prospecting in control of coal seam occurrence form has demonstrated its satisfying effects,but for a mine's high yield,high efficiency geological guaranteeing system still need to determine geological anomalous bodies of“barren zone”,subsided column,gob area and coal seam outcrop etc.
三维地震勘探在控制煤层赋存形态方面已取得了令人满意的效果,但矿井高产高效地质保障系统需要准确圈定“无煤带”、陷落柱、老窑采空区、煤层露头等地质异常体。
