唐家会煤矿透明地质保障系统构建及示范

Construction and demonstration of the transparent geological guarantee system in Tangjiahui Coal Mine

唐家会煤矿智能化建设面临导水断层发育、带压开采等制约因素,地质条件不透明成为智能开采的技术瓶颈。唐家会煤矿以奥灰水害防治为重点,采用孔中瞬变电磁、孔间电阻率、随掘地震、随采地震、微震监测5项先进技术,构建了实时动态透明地质保障系统,实现基于透明地质模型的水害防治、快速掘进和智能回采3个目标,以支撑自主截割快速掘进和自主规划智能回采2条智能采掘作业线,其中,随采地震探测技术在61304智能回采工作面超前80 d、344 m发现了SYC1异常区并持续跟踪预报,现已得到回采揭露验证。透明地质保障系统的示范应用,取得了显著的经济效益和社会效益:①61304工作面解放了受奥灰水威胁近100万t煤炭资源;②61302快速掘进工作面的进尺由原来的260 m/月提高到352 m/月;③61304智能开采工作面日常用工减少70%。

The intelligence construction of Tangjiahui Coal Mine is confronted with constrains such as water-conducting faults and pressure of Ordovician limestone water,and how to make the geological conditions transparent has become the technical bottleneck of intelligent mining.Tangjiahui Coal Mine puts emphasize on the prevention and control of water disasters and adopted five advanced technologies,including borehole transient electromagnetic technology,multi-borehole resistivity,seismic while excavating,seismic while mining,microseismic monitoring to build a real-time dynamic transparent geological guarantee system.The system realizes the prevention and control of water disasters,rapid excavation and intelligent mining based on transparent geological models,which supports the two intelligent mining operation lines of autonomous cutting and fast excavation as well as autonomous planning and intelligent mining.In particular,the SYC1 anomaly area is found 343 m ahead of the 61304 intelligent working face,80 days ahead of schedule by the seismic detection technology,and the anomaly can be tracked and forecasted continuously,until it was exposed and verified in the real mining process.The demonstration application of the transparent geological guarantee system has achieved remarkable economic and social benefits as follows:Nearly 1 million tons of coal resources were relieved of the threat of Ordovician limestone water in 61304 working face;The footage of the 61302 fast excavation face is increased from 260 meters a month to 352 meters a month;Daily labor of 61304 intelligent mining face is reduced by 70%.
