| 摘 要： | 为了探明某研究区采空区和采空积水区情况，采用瞬变电磁法、激电测深法、电法探测法、活性炭测氡法，并利用钻探进行验证。研究得出，物探工作查明8号煤层采空区异常4处，推断采空面积共计422 309 m2；12号煤层采空区异常4处，采空面积共计371 1692 m2；15号煤层采空区异常2处，采空面积共计282 4437 m2。该井田内各煤层共有采空积水区55处，矿井总积水面积为1 037 517 m2，总积水量2 253 232 m3。研究为后期矿山地质环境功能修复提供了依据。

| Abstract: | In order to find out the goaf and goaf ponding area in a study area，transient electromagnetic method，IP sounding method，electrical method and active carbon radon measurement method were used，and drilling was used for verification.The study showed that geophysical exploration has found out 4 abnormalities in the goaf of No.8 coal seam，and the inferred goaf area was 422 309 m2 in total;There were 4 abnormalities in the goaf of No.12 coal seam，with a total goaf area of 371 169.2 m2;There were 2 abnormalities in the goaf of No.15 coal seam，with a total goaf area of 282 443.7 m2.There were 55 goaf ponding areas in all coal seams in the mine field，with a total ponding area of 1 037 517 m2 and a total ponding volume of 2 253 232 m3.The study provided a basis for the functional restoration of the mine geological environment in the later period. |
