为了确保羊东矿8472工作面的顺利回采,诠释了在煤矿复杂地质构造发育及奥灰水高承压地区采取先物探后钻探治理的联合手段的有效性。羊东矿8472工作面采用结合物探及区域治理等多重手段,综合探查工作面内及深部是否存在含水构造发育情况。物探选用瞬变电磁、电测深、槽波地震3种物探手段对该工作面及工作面以下的半空间进行了覆盖性探测,区域治理主要针对大青灰岩段进行治理工程。该技术确保了工作面的安全回采,证实了在复杂地质条件下,采取有针对性的物探控制工作面周围80 m空间范围内的含水地质隐患;钻探治理工作面下深部含水层,将含水层转变为隔水层,充分降低了突水系数,可极大提高工作面回采的安全系数。
In order to ensure the smooth mining of No.8472 Face in Yangdong Coal Mine, the effectiveness of the combined means of geophysical prospecting and drilling contorl in the complex geological structure development of coal mine and the high pressure area of Ordovician limestone water was explained. No.8472 Face of Yangdong Mine adopted multiple means such as geophysical exploration and regional control to comprehensively explore whether there was water-bearing structure development in the working face and deep part. Three geophysical exploration methods including transient electromagnetic, electrical sounding and channel wave earthquake, were used to detect the working face and the half space below the working face. The regional control was mainly aimed at the Daqing limestone section. The safe mining of the working face was ensured. It was proved that the following method could fully reduce the water outburst coefficient and greatly improved the safety factor of working face mining under complex geological conditions. which included taking targeted geophysical prospecting to control the hidden dangers of water-bearing geology within 80 m space around the working face, drilling to control the deep aquifer under the working face, and transforming the aquifer into an aquifuge.
