Prevention and control technology of Ordovician water in Tangjiahui Coal Mine based on transparent geology

  • 摘要: 唐家会煤矿6号煤开采面临导水断层多、隐伏导水构造发育,奥陶纪灰岩(简称奥灰)水害防治难度大的问题。经过不断的探索和实践,唐家会煤矿引进多种先进技术,获取大量地质、水文地质数据,构建智能地质保障系统,形成“物探钻探探查、井上下联合注浆治理、孔中瞬变电磁精细探查、注浆效果孔间电阻率检测、煤层底板微震电法联合监测”的技术思路。通过融合各类静态数据、动态数据、实时数据,完成断层、破碎带、含水层、低阻异常区等充水因素的数字建模,使地质要素、钻探物探数据可视化、透明化,以此为依托,建立一套基于透明地质的奥灰水害全时空防治体系,实现带压开采条件下奥灰水害的精细探查、靶向治理、效果检测和回采监测,取得了良好的应用效果。
