二维地震勘探技术在煤矿采空区探测中的应用

通过对勘探区地质概况及地震地质条件的分析,采用二维地震勘探技术,确定最佳的的观测系统和采集参数,并结合地质条件,选择合适的处理参数。通过资料对采空区反射波特征进行研究,结合地震剖面和地震波属性,对采空区的分布范围进行了解释,解释结果与矿方资料吻合较好,说明该方法适用于煤矿采空区的探测,且效果较好。

Based on the analysis of geological situation and seismic geological conditions in the exploration area,the best observation system and acquisition parameters are determined using two-dimensional seismic exploration technology,and the appropriate processing parameters are selected in combination with geological conditions.The characteristics of reflected wave in goaf are studied through data.combined with seismic profile and seismic wave attribute,the distribution range of goaf is explained.the interpretation results are in good agreement with the mine data,which shows that this method is suitable for the detection of goaf in coal mine.And the effect is good.
