| Fuxin is a result of the coal and the establishment of coal and energy, Forming a large area of underground coal mining goaf. Ground subsidence caused by the presence of goaf to give the people’s living causing seriously troubled. Now it becomes one of the the main factors affecting the region social stability. It shows that goaf stability evaluation is importance.The issues surrounding mining empty area of surface stability issues, from the the goaf surface movement principle to goaf surface stability analysis. Through a lot of mathematical statistics and observations to get the calculation of empirical parameters fit in Fuxin goaf subsidence. As a basis for in order to Qinghemen industrial park’s surface stability evaluation as an engineering example. Systematic exposition of the Fuxin region goaf surface movement and the surface of stability calculation to conduct a comprehensive evaluation of stability of Fuxin goaf surface. |
