【Abstract】 Based on analysis of the actually observed data of ground movement due to mining of the No.1315 Fully mechanized coal face,the law governing the ground movement under such conditons has been brought to light,and the parameters for calculating the ground movement have been obtained.This provides a technical basis for the optimum design of mining beneath surface buildings,railways and water bodies.更多还原
