| 摘 要： | 某矿井目前主要开采山西组煤，为保证下部太原组煤的安全开拓，需查明其底板的水文地质条件。根据该矿井的地质条件，采用井下瞬变电磁法小线框的工作方式，在一采区-530m水平及其以上相关大巷及17煤首采工作面两顺槽内布置6条测线进行探测。在资料解释中，通过设定2级异常阀值对井下富水性进行评价，查明了巷道底板的含水性。经验证，资料处理解释结果与实际揭露地质构造对应良好。

| Abstract: | At present, a coalmine is mainly mining the coal seams in the Shanxi Formation. To ensure safe mining of the Taiyuan Formation coal seams under, should fined out floor hydrogeological conditions. According to geological conditions of the coalmine, using underground TEM small loop operation mode, laid out 6 lines in the No.1 winning district -530 level and related main roadway above, as well as two crossheadings of No.17 coal seam first winning face. In the data interpretation, assessed underground water yield property through 2 levels anomalous threshold values setting, found out water-bearing property of roadway floor. After verification, the data processed and interpreted results are properly corresponding with geological structures. |
