三维地震勘探技术在煤矿采空区探测中的应用
|
摘要
本文以三维地震勘探技术在陕北韩家湾煤矿的应用为基础,通过对小煤窑采空区和煤矿综采形成的采空区特征认识、总结,结合地震剖面和提取的地震波最大振幅属性,解释了采空区的分布范围,解释结果与矿方钻探资料对比,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 3-D seismic exploration technology in the application of the Northern Shaanxi mining HanJiaWan coal,Through the formation of the minedout area characteristics of the small minedout area and fully mechanized coal mine,sums up the understanding on seismic profile and extraction maximum amplitude attributes of seismic wave,explained the distribution of mined-out area,the results of explanation and ore party material contrast,I obtained a good result,which provide a good method for coal mining area detection small mines cross-border mining.
