摘要
Abstract
Pointing to the possibility of water inrush in No.17 coal floor in Ordovician limestone when mining in nan⁃tun coal mine, by using the fuzzy bursting water coefficient law and imensionless information fusion, comprehen⁃sively prediction and evaluation have been carried out. Risk zoning of Ordovician limestone aquifer water inrush has been classified and the degree of influence factors has been determined. The most dangerous water inrush areas mainly distributed in the northeastern part of coal mine, safe areas mainly distributed in the western boundary of the mine, and the rest areas are the more dangerous areas. The mining depth and aquifer water pressure are the main factors of the danger of water inrush in the process of No.17 coal mining.关键词
