摘要
为保证煤矿安全开采,为开采中工作面的布置提供技术规划,通常采用三维地震勘探的方法对地下构造进行探查。常规三维地震多在陆地进行,采区位于水体覆盖区域,则需采取特殊的采集措施进行水面地震勘探。以新安煤矿找矿为例,通过采取一系列技术措施,最终准确圈定煤层赋存范围,获得较为可靠的地质成果。
In order to ensure the safety of coal mining and provide technical planning for the layout of working face in mining,the method of three-dimensional seismic exploration is usually used to explore the underground structure.Most of the conventional three-dimensional earthquakes are carried out on land,and the mining area is located in the area covered by water,so it is necessary to take special acquisition measures to carry out surface seismic exploration.Taking the prospecting of Xin’an Coal Mine as an example,a series of technical measures are taken to accurately delineate the overlying area of coal seams and obtain more reliable geological results.
