Abstract

Abstract: Based on the experiment with similar material, the top of the goaf was loaded the pressure several times. The XJTUDP system was used to observe the process the model. The laws of the subsidence under different loads and the laws of deformation of rock with different depths were obtained. Through regression analysis, the formula for expected the subsidence under the pressure is proposed, which can provide the basis for evaluation and treatment measures of the new buildings over the goaf.
