综合物探法在陷落柱探测中的应用
|
摘要
陷落柱的发育严重影响煤矿的安全生产及生产进度,有必要对疑似陷落柱进行探查。针对许疃煤矿72煤7229工作面运输巷底板下发育的疑似陷落柱,利用三维直流电法、地震反射扫描技术以及地震波三维反射偏移技术等综合物探方法进行探测。实践表明,综合物探方法不仅能解决勘探的精度问题,还可以查明疑似陷落柱的其他特性(如富水性及构造特征等)。
The development of the collapse column seriously affected the safety production and work schedule,so it is very necessary to detect the suspected collapse column.Based on the suspected collapse column developed on 7229 working face in Ⅶ2 Coal Seam in Xutuan Coal Mine,comprehensive geophysical exploration methods were used to solve the problem of collapse columns,including 3D direct current survey,seismic reflection method and seismic wave reflection common migration technology.Practice shows that,the application of comprehensive geophysical exploration methods can not only solve the problems of the exploration accuracy,but also find out the other characteristics of suspected collapse columns,such as water content and structural features.
