基岩裸露山区倾斜煤层开采地表沉陷规律研究

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

为掌握松藻煤矿采动地表移动变形规律及开采沉陷参数,该矿在2316工作面上方建立了地表移动观测站。通过系统分析观测站实测资料,研究得到了基岩裸露山区倾斜煤层开采地表移动变形规律及特点,并求取了相应的动态地表移动参数、岩移角参数,以及概率积分法地表沉陷预计参数,为松藻煤矿适中街区建筑群下采煤的实施提供了科学依据。

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.
