摘要: 为了预测煤矿掘进工作面的水害,采用矿井瞬变电磁法、矿井直流电法、矿井瑞利波法、矿井反射波法4种井下超前探测技术。通过井下数据采集、处理和反演计算,形成可视化图件,来解释矿井含水体及构造的范围和位置特征,建立了一套适合煤矿掘进过程中井下物探动态监测水害的技术方法。结果表明:矿井瞬变电磁法可探测掘进工作面正前方、前方顶板、前方底板和前方侧帮含水体;矿井直流电法可探测掘进工作面正前方含水体;矿井瑞利波法(或矿井反射波法)可以探测前方构造及采空区边界。Abstract: Mine transient electromagnetic method,mine direct current method,mine rayleigh wave method,mine reflected wave method four kinds of mine advanced detection technology are adopted to forecast water disaster in coal mine heading face.By the mine data acquisition,processing and inverse calculation,visualization graph is formed,and use it explain range and location characteristic of the mine water-logged stratum and structural,so as to build built a set technology method for mine geophysical dynamic monitoring water disaster in coal mine tunneling process.Result indicates that mine transient electromagnetic method may detect heading face water-contained of positive front,front roof,front floor and front sidewall;mine direct current method may detect heading face water-contained of positive front;mine rayleigh wave method(or mine reflected wave method) may detect front structure and goaf boundaries.
