矿井深部复杂含煤区域断层探测实践

结合井田断层发育特点及构造充水特征,通过在北翼边界回风巷开展矿井震波超前探测及矿井瞬变电磁探测,并基于其探测成果,针对性的开展了钻探验证工作,结果显示:①在3206下顺槽里端向外85m范围内不存在断裂。②所探范围不存在与强含水层贯通的导水裂隙,由此推断工作面对应范围不存在来源于外侧水平以上方向的水害隐患。③震波超前探测及矿井瞬变电磁探测在矿井深部复杂含煤区域的背景下,对断裂探测的成果具有可靠性,可为其他矿井深部断裂探测提供借鉴。

Fault Detection Practice of Complex Coal Bearing Area in Deep Mine

Combined with the characteristics of fault development and structural water filling in the mine field,the mine seismic wave advance detection and mine transient electromagnetic detection are carried out in the North Wing boundary return air lane.Based on the detection results,the drilling verification work is carried out pertinently.The results show that:①there is no fracture within the range of 85m from the inner end to the outer end of the trough in 3206.②It is concluded that there is no hidden danger of water damage in the working face from the direction above the lateral level.③Under the background of complex coal bearing area in deep mine,seismic wave advance detection and mine transient electromagnetic detection are reliable for fault detection results,which can provide reference for other deep fault detection in mine.
