Study on mining subsidence affected to high buildings

The main factor of destruction high buildings was drawn by analyze of the mechanisms of various surface movements and deformations due to mining subsidence on the affection of the buildings and the features of high buildings,it is the slope.According to surface allowable and ultimate value,high buildings destruction was divided into three ranks,i.e.,mild,moderate,serious.The mining subsidence affected to high buildings was divided into category 1 and category 2 affection,based on the final mining subsidence affected to high buildings.The measures to protect high buildings against mining subsidence were discussed,and a thought was put forwarded that high buildings destroy can be analyzed using simulate.An affection of mining subsidence was analyzed for a chimney which is near 112103 working face with probability integral method as the prediction model.
