Study on Surface Subsidence and Separation Range Thick Seam Mining of Daping Mine

Abstract:

In order to study the surface subsidence and separation range features during the mining process in in thick seam mining of Daping mine , it takes the typical coal of mining in S₂S₉ face of Daping Mine, using the resemble simulation to study on it. The study showed that the subsidence amounted to less than the maximum under the geological and mining conditions, In the single-face mining conditions, when the face length is generally not more than (1/3-1/4) H.The mining thickness cannot deflection in the form completely transmitted to the surface, but abound in overburden bed rock mass formed within the fracture and caving into the residual space. This research can be a reference for safety and high efficient coal mining of other working face in Daping Coal Mine.
