Abstract: In order to explore the influence law of close distance coal seam mining on overburden rock stress and displacement development, and effectively prevent disasters such as roof fall and caving, rock burst and others caused by close distance coal seam mining in coal production, taking Dananhu No. 1 Mine in Hami as an example, through methods of theoretical analysis and numerical simulation, the overburden rock migration characteristics in close distance coal seam mining are explored. The results show that the lower coal seam mining at close distance coal seams exacerbates the stress concentration and displacement deformation of the overburden rock, directly increasing the roof safety hidden dangers caused by close distance coal seam mining. Therefore, a delayed filling mining method for the upper coal seam is proposed, which can effectively alleviate the impacts caused by stress concentration and displacement deformation of the overburden rock, and achieve relatively effective control.
