Study on Surface Subsidence Law of Inclined Seam Mining in Mountain Area with Base Rock Exposure

In order to master the mining-induced surface movement and deformation law and the surface subsidence parameters in Songzao Mine, the surface movement observation stations were set up above 2316 working face in this mine. Through the systematic analysis on the observed data at the stations, the surface movement and deformation law and characteristics of the inclined seam mining in the mountain area with the base rock explosure were studied, and the dynamic parameters of the surface movement, the angle parameters of the rock movement and the parameters of surface subsidence movement predicted with the probability integral method were obtained, this thus provided the scientific basis for coal mining under the street block buildings of Songzao Mine.
