Abstract

The long-term exploiting activity of coal mine threats the local ecological environment. Combined with surface level monitoring data of a mine in Jiangxi province, discussed the simplified dislocation model suited for coal mine, through the least squares method and Monte Carlo method to invert the Tensile component of mining area faulting. Comparing forward calculation data with level data, the accuracy of the inversion method has been analysis. The research results have realistic meanings for reducing the surface deformation mechanism due to the excavation in coal mine. It can provided theoretical basis for early warning of our country coal mining surface deformation.
