两淮矿区煤矿深部开采设计研究

Discussion on design of deep mining in Huainan and Huaibei Mining Area

两淮矿区经过多年高强度开采,采场逐步向深部转移,安全生产面临新挑战。依据两淮矿区煤矿近年安全生产现状和深部开采条件,结合现有灾害防治关键技术,从设计源头入手,在延深方式、井筒布设、水平设置、辅助运输系统等方面提出设计思路和对策,为两淮矿区深部开采及类似矿井设计提供了技术支撑和借鉴。

After decades of high-intensity mining,the shallow high-quality resources of the coal mines in the Huainan and Huaibei Mining Area have been gradually depleted,and the stope has gradually shifted to the deep,and mine safety production is facing new challenges.On the basis of the statistical analysis of the status quo of coal mine safety production in the past ten years,combined with the actual production situation and the existing key technologies for disaster prevention and control,starting from the design source,the design ideas and countermeasures were put forward in the aspects of extension mode,shaft layout,horizontal setting and auxiliary transportation system,which provides technical support and reference for the deep mining and similar mine design in Lianghuai mining area.
