Research on the Design for Strip-Partial Mining Method under Villages at Xiaotun Colliery
Basing on the geological mining condition under villages at Xiaotun Mine, according to the existing theories of the strip-partial mining, using the method of analyzing the field measurements date and calculating by empirical formula, the safe range of mining and retained widths can be confirmed, the mining schemes for different widths of coal pillar can be designed, and the optimum scheme can be worked out; and then the coal pillar stability of each mining scheme will be calculated through numerical simulation analysis, providing the basis for appropriately selecting the optimum scheme; on this basis, through simulation prediction of the surface movement and deformation, the surface movement and deformation laws of strip-partial mining is revealed to guide production of Xiaotun colliery.
