Abstract

Water inrush risk zoning and water conservation mining technology are of significant importance for safe mining and environmental protection of the Jurassic coal seam in the fragile eco-geological environment of Western China. Statistics, theoretical analyses and numerical simulations are applied to divide and classify water inrush risk areas. A water conservation mining technology is put forward for the Shennan Mining Area (SMA). Firstly, this paper illustrates the inapplicability of the existing empirical formula for development height of water flowing fractured zone (DHWFFZ) derived from data from Carboniferous Permian coal mines to Jurassic coal fields. Secondly, a method for water inrush risk zoning method is proposed, which includes data statistics \(\rightarrow \) the new empirical formula of DHWFFZ \(\rightarrow \) prediction of DHWFFZ in SMA \(\rightarrow \) the effective thickness of the aquiclude \(\rightarrow \) water inrush risk areas. Water conservation mining technology with strip-pillar mining is presented for areas at risk of water inrush, and the optimal strip size is determined based on the theoretical analysis and Realistic Failure Process Analysis software. Results provide a theoretical basis for the safe mining of the Jurassic coal seam in Western China.
