地面电法物探勘查在苏村矿多层煤采空区探测中的应用

Application of Surface Electrical Geophysical Exploration in Multi-layer Coal Goaf Detection in Sucun Mine

为查明苏村矿四采区和二采区北翼范围内6号、10号煤层采空区积水情况,采用瞬变电磁法和测氡法进行勘查,探测到四采区6号煤层异常区5个、10号煤层异常区6个,二采区北翼6号煤层异常区7个、10号煤层异常区8个。

In order to find out the water accumulation in goaf of No.6 and No.10 coal seams in No.4 mining area and No.2 Mining Area of Sucun mine,transient electromagnetic method and radon measurement method were used for exploration,and 5 abnormal areas of No.6 Coal Seam and 6 abnormal areas of No.10 coal seam were detected,7 abnormal areas of No.6 Coal Seam and 8 abnormal areas of No.10 Coal Seam in North Wing of No.2 Mining Area.
