正行煤业老窑采空区积水边界探测技术

Zhenghang Mining Industry Old Mine Area Water Boundary Detection Technology

山西汾西瑞泰井矿正行煤业有限公司整合前周边煤矿越界现象严重,老窑采空区分布广,边界不准确,三盘区东、南侧受老空区积水威胁。经水文地质补充勘探估算老空区积水面积为682743m2,积水量约为1073181m3。针对这一问题,通过地面、井下瞬变电磁勘探成果分析,并与井下钻探相结合,探查空区边界,疏放空区积水,以保证三盘区的安全施工。

Shanxi Fenxi Ruitai Jingxing Mining Group Zhenghang Mining Industry Corporation around the coal mine cross-border phenomenon was serious before integration, with broad goaf, inaccurate borders, cast and south of Sanpan Area threatened by old mine area water. Through supplement hydrogeological exploration, old mine area water area was estimated by 682 743 m^2, water volume was 1 073 181 m^3. Based on this problem, through analysis of the ground, underground transient electromagnetic exploration achievements, and combined with borehole drilling, exploring the empty area boundary, discharging goaf water, which ensured Sanpan Area construction safe.
