| 摘 要： | 深水区煤田地震勘探的主要困难是水下激发与接收，结合岳城水库的地表赋水特点，进行了激发与接收的实验，在4种接收方法中水下密封检波器与水库底面偶合好，抗水域次级震动能力强，接收效果较好；在激发实验中，选用了由铁管成孔并沿孔内壁下药进行激发的方法，其激发能量大，穿透力强。

| Abstract: | Main difficult of coal seismic prospecting applied in deep water area is underwater shotting and receiving. According to surface water hosting characters in Yuecheng reservoir carried out experimental shotting and receiving. In the four receiving methods, the underwater air-tight sealed geophone has better coupling with reservoir bottom, withstand ability of secondary quake in waters and receiving effects; in shotting experiment, using iron pipe boring and lowering powder along the inner wall of bored holes, it has larger shotting energy and penetrability. |
