摘要
为避免矿井在回采过程中遇陷落柱突水而导致的安全事故,保证工作面安全回采,在马道头煤业8106回采工作面通过陷落柱前进行勘察治理。根据物探结果,在5106顺槽切眼前方1 080~1 140 m范围内存在富水异常区;根据物探及钻探结果,施工加固治理钻孔37个,水泥注浆量63.84 t。治理后物探结果与治理前区域进行对比,未发现明显异常区。
In order to avoid safety accidents caused by water inrush from collapsed pillars during the mining process of the mine and ensure safe mining of the working face,investigation and treatment have been carried out before the 8106 mining face passes through the collapsed pillars.The geophysical exploration results indicate that there is a water rich anomaly area within the range of 1080-1140 m in front of the 5106 entry cut.37 boreholes have been drilled for construction reinforcement and treatment,with a cement grouting volume of 63.84 tons,which proves that there are no obvious abnormal areas.
