摘要
隐性浅埋房柱式采空区是陕北侏罗纪煤田许多煤矿下部煤层开采的重大安全隐患.针对这-问题, 在对勘探区地球物理特性研究分析的基础上, 综合运用瞬变电磁和高密度电法, 对陕北某矿计划开采区域的上部浅埋房柱式采空区进行综合勘查. 经施工钻孔验证, 综合探测成果基本查明了隐性采空区的埋藏深度、 分布范围和积水情况. 研究结果表明 瞬变电磁和高密度电法的综合物探方法在采空区探测和综合解释方面精度和准确度较高, 具有广泛的应用前景, 能够为类似矿井下部煤层的安全回采和采空区的综合治理提供科学依据.
Recessive room and pillar goaf in shallow was large potential safety hazard for downward coal seams mining of many coalmine of Jurassic coalfield in Shanbei, to this problem, based on geophysical characteristic of exploration area, transient electromag-netic and high density resistivity were applied, room and pillar goaf that upward of mining area in planning of one coal mine in Shanbeiwas explored synthesize. Then the burden depth and distribution scope and hydrocele of recessive goaf were ascertained by it, the re-sults was verified by practical drilling hole. The results showed that the synthesize exploration method of transient electromagnetic andhigh density resistivity has high precision and accuracy rate on goaf exploration and synthesize illustration, it has a very wide range ofapplications, it references for similar situation.
