Inorder to safely mine the coal under the Ru river, this paper predicted the mining subsidence caused by 11071 coalface using the probability integration method, according to the geological and mining conditions of Jiyi mining area of Pingmei group 13mine, and analyzed the impact on the embankment caused by mining under Ru river. Besides, this paper clarified the development law of the cracks on the ground surface and embankment and the maximum depth of the cracks on the ground surface in this area to determine the cracks management range, and put forward the management project, and it is very significant to safely mine the coal under the Ru river.
