塔山矿8228工作面突水区域井上下综合物探分析及治理方案

Comprehensive Geophysical Exploration Analysis and Treatment Scheme of Water Inrush Area in the 8228 Working Face of Tashan Coal Mine

为有效治理8228工作面突水危险区域,通过直流电法、瞬变电磁法和音频电透视等物探方法进行工作面区域赋存情况的探测分析,采用地面CSAMT探查对工作面富水情况进行分析,基于物探分析结果确定工作面突水为奥灰含水层通过一疑似导水陷落柱涌入巷道;设计突水区域治理采用地面定向钻进注浆拦截,采掘煤层顶底板注浆加固。根据现场应用效果可知:治理方案实施后,工作面最终实现了安全生产。

In order to effectively control the dangerous area of water inrush in the 8228 working face,the occurrence situation of the working face area is detected and analyzed by direct current method,transient electromagnetic method,audio frequency electric perspective and other geophysical methods,the surface CSAMT exploration is used to analyze the rich water situation of the working face.Based on the results of geophysical analysis,it is determined that the water inrush in the working face is ordovician ash aquifer pouring into the roadway through a suspected water diversion collapse column.The design of water inrush area treatment adopts surface directional drilling and grouting interception,and the roof and floor of the mining coal seam is reinforced by grouting.After the implementation of the treatment scheme,the safety production of the working face has been realized.
