摘要
侏罗系红层水是兖州矿区主要水害之一。为防治红层水害,对兖州矿区红层的物质组成、红层孔隙微观特征及分形特征、红层的渗透性、岩石力学特征、采动条件下覆岩破坏高度数值模拟、采动条件下红层裂隙的发育规律与渗透特征、红层突水判别模式及突水危险性分区等进行了研究,建立了红层突水判别模式,得到兖州矿区红层突水危险性分区图,对类似条件矿区的水害防治具有一定的参考价值。
Jurassic red strata water is one of main hazard in Yanzhou coal mining area. In order to control red strata water, the red strata material composition, microporosity and branch, rock mechanical characteristics and permeability are measured, meanwhile the distraction height numerical simulation of coal seam roof strata and fracture development rule caused by mining action are described, and red strata water inrush criterion and danger division in Yanzhou coal mining area are presented. The study established identification model for red strata water and obtained a water dangerousness zone dividing map, which would be have some references value of water hazard control for other similar coal mining area.
