摘要
通过对钻孔超前探水技术原理进行分析,得出该技术抗干扰能力强,同时对微弱信号较为敏感,是一种较好的巷道超前探水方法。对矿井的回风槽应用YZT6钻孔超前探测仪进行了实际探测,采用视极化率和视电导率两个参数进行隐患评估。探测数据结果表明,掘进方向存在3处异常点,分析后推测,在中心半径40m范围内,2#孔63m和3#孔45m处存在裂隙隐患区,3#孔59m处存在积水采空区引起的联通异常体。
Analyzed the principle of drilling advanced water detection technology,and knows that this technology has strong anti-interference ability and is sensitive to weak signals at the same time.It is a good method for advanced water exploration in roadways.The YZT6 borehole advance detector was used to detect the air return groove of the mine,and the visual acuity and apparent electrical conductivity parameters were used for hidden danger assessment.The results of exploration data show that there are 3 abnormal points in the driving direction.It is assumed that in the range of 40m in the center radius,there is a hidden-hazardous area in 63m and 3#holes 45m in the 2#hole,and there is a water-accumulating gob in the 3rd hole 59m.
