ABSTRACT

The coal mining will cause a series of damage to the overlying strata and surface soil, through the study of rock and soil of the earth surface movement and deformation mechanism, we can forecast range, three rock band distribution and ground surface movement and deformation degree, which has important significance for prevention of geological disasters, geological environmental protection and sustainable development in mining area. By means of numerical simulation and similar material simulation, this paper forecasts the change of overlying strata and surface soil layers, and provides a reference for mine environmental protection.
