Abstract
Based on data of ground objects and drilling results, 9214 working face in North Dongpang Mine threatened by goaf water and Ordovician limestone rock water, crossing small mine goaf, according to hydrogeological condition of the working face, the goaf water detection was conducted, and the corresponding measures were adopted to remove the goaf water threaten, the depth and density of the foundation were reinforced by grouting. Water resistance capacity of the bottom plate of the working face and the integrity of the bottom plate of the working face was improved, thickness of the aquifer was increased, these technology ensured the safe mining of the working face.关键词
