摘要:In search for detecting the working status of curtain under high-head condition, finding fracture extension zone around curtain while the mine was extracted, particularly, pointing out possibly water inrush passageway along curtain mining sides. Microseismic monitoring system was established to monitor real-time and continuous microrupture of curtain region by the advanced mining dynamic disaster monitoring equipment in the Zhangmatun iron mine,and combining with the water amount changes at every mining levels and different observating holes, judging comprehensively the stability in curtain region. The monitoring results show that the two obvious fracture extension zones were found along curtain mining sides, diffusing distribution showed ray state from curtain inside to outside, the pit inflow of water was bigger than other site in this two regions, both microseismic monitoring and water amount changes results were anastomosous relatively. The fracture was developed in this two regions, the hydraulic relationship was also close, and the water inrush accident may occur, so the reinforcing curtain and plugging water inrush passageway should be took timely.
