Intelligent microseismic ground monitoring is implemented for coalbed methane fracturing ver-tical well in Weizhou Mining Area.With the wellhead as the center,40 high-precision geophones are in-stalled.Effective event detection is performed using the STA/LTA method.The REAL method is used for locof picking events.A total of 53 effective microseismic events are identified in the fracturing section.It is inferred that the maximum average influence radius of fracturing construction is 178m.The crack com-binations are primarily near-horizontal,with the maximum fracture length extending about 210m,the maximum fracture width approximately 10 meters,and the maximum fracture height around 6 m.The pri-mary direction of in-situ stress is NNW-SSE,consistent with the inferred principal stress direction.The monitoring results show that the coalbed methane fracturing microseismic ground monitoring in the area with thick cover has certain applicability.
