煤田坡积物区三维地震勘探采集的难点与对策

Difficulties and countermeasures on data acquisition of 3D seismic exploration in coalfield slope sediments area

随着我国煤田三维地震勘探的重点从中东部向西部转移,从平原转向山区,表、浅层地震地质条件复杂,有风化基岩、坡积物、土石混杂等,给三维地震勘探野外数据采集带来了非常大的困难。本文以豫西某矿为例,着重针对复杂地表条件提出了采集的具体措施。经过对结果处理与解释,所取得的资料比较满意,符合本区的地质构造规律。

The coalfield 3D seismic exploration is moving from the east to the west,from the plains to mountainous area.For the complex geological conditions in slope sediments area,the field data acquisition of 3D seismic exploration is very difficult.The paper proposed specific measures for data acquisition in complex surface conditions of a coal mine.By the processing and interpretation,the data obtained can illustrate the geological structure law in this area.
