地表建筑物下的三维地震勘探方法及效果

Three-D seismic exploration method and result for the area occupied by buildings

三维地震勘探已在煤炭开采中广泛应用并取得了好的效果,目前已经成功开展了平原、戈壁、山区、水上三维地震勘探工作,但是对于在建筑物下开展三维地震勘探工作,还有许多问题需要解决,如震源、接收、采集方法、资料处理等问题。本文介绍了地面建筑物之下成功开展的WL煤矿某一采区三维地震勘探工程项目,及获得的较为理想的地质成果。

Three-D seismic exploration has been widely applied in coal mining and brought good result.So far successful explorations have been made in plain,Gobi,mountainous area and water,but how to perform it under buildings has many issues to solve,such as seismic source,receiving,collecting method,data processing,etc.This paper introduced a three-D seismic exploration project in a mining area of the WL coal mine under surface buildings and the good geological results obtained.
