浅析全方位探测仪在井下超前探测中的作用

Brief Discussion on Effect on Advanced Detection under the Shaft of Comprehensive Detecting Instrument

太原煤气化公司嘉乐泉矿以前一直沿用钻探和巷探的方法来探测煤层附近采空区的积水和断层,这种方法不仅工作效率低、现场施工强度大,而且探测距离小、定向性差,探测效果不理想。全方位探测仪是近年来发展很快并在矿井下已经应用的一种电法勘探设备,可用于井下全方位探测,具有安全性能好、技术性能优越、灵敏度高、操作使用方便、体积小和重量轻等显著特点,特别适用于井下水害探测预报。文章针对全方位探测仪来探讨井下巷道探测技术,为井下巷道探测工作提供参考。

Jialequan Mine of Taiyuan Coal Gasification Co., Ltd detect coal seam near the gob water and fault using drilling and lane agent. This method not only low efficiency and large intensity of field construction, but also the detection range is small, bad directionality and the detection effect is not ideal. All-round detector is electrical prospecting equipment developing rapidly in recent years and has been used under the mine, which could be used in underground comprehensive detection with good safety performance, superior technical performance, high sensitivity, convenient operation and other significant character-istics of small volume and light weight, especially suitable for the mine water disasters detection report. Aiming at compre-hensive detectors, the paper was discussed detection technology under the shaft and hoped to provide references for detection work under the shaft.
