Abstract

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.
