复杂条件下千万吨矿井科技减人提效研究与实践

基于刘庄煤矿安全生产过程中存在的生产环节多、采掘工作面数量多、单班入井超千人等难题,通过优化采掘布局、建立煤矸分时分运系统、探索应用深浅孔联合注浆巷修工艺、研发综采工作面成套回撤工艺等举措,大幅度减少了全矿总人数、单班入井人数,降低了原煤生产成本,提高了安全保障能力。

Research and Practice of Reducing Manpower and Improving Efficiency in Ten-million-ton Mine under Complex Conditions

There are many problems in the process of safe production in Liuzhuang Coal Mine,such as many production links,more mining faces and more than one thousand workers entering the shaft in a single shift.In view of these problems,some measures are put forward,such as optimizing the mining layout,establishing coal and gangue different-time transport system,trying to apply the deep and shallow hole grouting technology for roadway repair,and developing the complete set of withdrawal technology in a comprehensive mining working face,etc.The implementation of these measures has greatly reduced the total number of personnel in the whole mine and the number of workers entering the shaft in a single shift,lowered the cost of raw coal production,and improved the safety of the mine.
