基于透明地质的唐家会煤矿奥灰水防治技术

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。 

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

The problems of many water diversion faults and, concealed water diversion structure have led to the difficulty of water disaster prevention and control of Ordovician limestone in No.6 coal seam in Tangjiahui Coal Mine. After continuous exploration and practice, a variety of advanced technologies has been introduced to obtain a large number of geological and hydrogeological data, and construct an intelligent geological guarantee system. The technical ideas of “geophysical and drilling exploration, joint grouting treatment up-hole and down-hole, in-hole transient electromagnetic fine exploration, inter-hole resistivity detection of grouting effect, and joint monitoring of coal seam floor by micro-seismic and electromagnetic methods” are formed. Through the integration of all kinds of static data, dynamic data and real-time data, the digital modeling of water filling factors such as faults, broken zones, aquifers and low resistivity anomaly areas is founded, so as to make geological bodies and drilling and geophysical data visible and transparent. Then a whole time-space prevention and control system of Ordovician water disasters based on transparent geology is established, realizing the precise exploration, targeted treatment, effect detection and mining monitoring of Ordovician water disasters under the condition of mining under pressure. It has obtained satisfactory application results.
