摘要
Abstract
According to the technical conditions with insufficiency mining at 2103 working face under an industrial square of Handan mine area,prediction parameters are adjusted by the ratio of working face wide and depth.By using the revised parameters,surface subsidence is expected according to the probability integral method.It can be seen from the comparison of tilt observation values of surface construction caused by advancing part of the ground that the selection of parameter is reasonable.And it can be seen from the earth’s surface deformation law that various deformation values of insufficiency mining are samller than various deformation values of full mining.However,the subsidence basin turns to the downhill of coal seam because of the angle of coal seam,which will damage the buildings in inflection point of downhill seriously.关键词
