针对高瓦斯特厚煤层综放开采工作面,坚硬顶板的垮落对采场瓦斯涌出与冲击地压有决定性作用。根据宽沟煤矿综放工作面布置参数,必须施工不同的工艺巷采取超前爆破深孔预裂爆破的技术处理顶板,基于不同的工艺巷布置条件,对工作面通风系统进行了优化、改造以及实践。为工作面通风、瓦斯防治、顶板处理提供理论依据和技术支持。
For the fully mechanized top coal caving face of high-gsm thick coal seam, the collapse of hard roof has a decisive effect on gas emission and rock burst of stope. According to the layout parameters of fully mechanized caving face in Kuangou Coal Mine, it is necessary to construct different technology lanes to adopt the pre-blasting technology of advanced blasting to deal with the roof, and to optimize, reform and practice the ventilation system of the working face based on different arrangement conditions of process lane . Ventilation for the face, gas control, roof treatment to provide a theoretical basis and technical support.
