焦作市某煤矿拟建安置小区范围内有十余个村办小煤窑，先后开采过二1煤层和一5煤层，采深80～160 m，总采厚7.3 m左右。为准确分析评价采空区的稳定性，采用可控源音频大地电磁测深进行采空区探测。测区内完成测线8条，测点数75个，测线总长度3.75km。测量参数：发射偶极距AB为2 km，点距MN为25 m，收发距Rx为4.5～5.5 km，采集频率范围为7680~1 Hz。根据各测线反演得到的电阻率断面图进行解释，共圈出采空区4处、推断断层4条。经钻孔验证解释完全正确，推断出的上覆岩层冒落、断裂破坏及离层发育程度基本一致；与部分采掘工程平面图确认的的采空区边界基本吻合。

There were 10 more village run small coalmines in an allocation residential area proposed by a coalmine in the Jiaozuo City, the place once mined coal seams II1 and I5 successively with mining depth 80~160 m, total mining thickness about 7.3m. To correctly analyze and assess worked-out area stability, using controlled-source audiomagnetotelluric sounding carried out worked-out area pros?pecting. In the area has 8 prospecting lines, 75 survey stations, total prospecting line length 3.75km. Surveying parameters:emission di?pole moment AB is 2km, distance between electrode MN 25m, space between receiver and transmitter Rx 4.5~5.5km, acquisition fre?quency range 7 680~1 Hz. According to each line inversion obtained resistivity profiles carried out interpretation, totally have delineat?ed 4 worked-out areas, deduced 4 faults. After drilling verification confirmed the interpretation all right, deduced overburden strata caving, fracture failure and bed separation development degree essentially in agreement, basically coincided with some mining engi?neering plan confirmed worked-out area boundaries.
