摘要
利用矿井瞬变电磁快速、无损、对低阻体反应灵敏的特点,对巷道前方封堵不良钻孔的富水性进行了探测,并通过钻探进行了验证,为封堵不良钻孔的治理工作提供了依据,在保障煤矿安全生产的同时避免了资源的浪费。
Mine transient electromagnetic method was used to detect the Unfavorable-blocking boreholes, because of its characteristic of celerity, non-destructive and responsive to low resistivity body. The watery of unfavorableblocking borehole in n front of the roadway was probed and verified by drilling. The result can provide suggestions for unfavorable-blocking borehole governing to ensure the safety and avoid the waste of resources at the mean time.
