Abstract: Based on the geological mining conditions under villages in Xiaotun coal mine,and according to the existing theories of the strip mining,the safety ranges of mining and retained widths could be confirmed and the mining schemes for different widths of coal pillar could be designed by using the methods of analyzing the field measurement date and calculating by empirical formula.Then the coal pillar stability of each mining scheme was calculated through numerical analysis of finite differetial method,which provided 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 were revealed to guide production of Xiaotun coam mine.
