摘　　要：为了探测龙泉矿4204工作面在巷道掘进中揭露的f79、JF5断层及f75、f81断层在工作面中部是否相连,以及明确断层的产状要素,同时为工作面回采提供可靠依据,决定对4号煤层进行千米超前钻探。通过钻探结果表明,揭露的f79、JF5断层及f75、f81断层是走向相同的贯穿两条巷道的大断层。In order to detect whether the f79,JF5,and f75,f81 faults exposed during tunnel excavation in the 4204 working face of Longquan mine are connected in the middle of the working face,and to clarify the occurrence factors of the faults,while providing reliable basis for mining in the working face,it is decided to conduct kilometer ahead drilling on the 4th coal seam.The drilling results indicate that the exposed faults f79,JF5,and f75,f81 are large faults with the same strike that run through the two tunnels.
