Most of the microseismic events occur near the water-conducting fracture zone, where the energy density is concentrated to form the water-conducting fracture zone. In the numerical simulation, the concentrated distribution area of the fissure...

... widely used around the world at different types of mines [1,2]. A microseismic monitoring system normally consists of a network of individual geophones that are distributed at isolated locations around a mining area, sparsely spaced at 50–200 m.
