摘　　要：为减轻矿井深部冲击地压影响,对矿井采场进行调整,在浅部3^(上)煤采空区下寻找3煤、5煤煤层上移采场,确保矿井实现高效开采。通过分析3煤、5煤赋存情况,从工作面设计、掘进支护设计、放顶煤高效开采技术、分采分储分运系统设计等方面开展课题攻关,实现极近距离采空区下1(35)02N工作面3煤、5煤合层放顶煤高效开采,总结提炼出一套极近距离采空区下煤层群高效开采关键技术。To reduce the mine deep impact ground pressure, adjust the mine stope, 3 in shallow coal under the old mined-out area looking for 3, 5 coal seam coal up stope, ensure efficient mining.Through the analysis of 3, 5 coal coal occurrence conditions, from design, excavation support design, the caving mining technology with high efficiency, points by points storage and transit system design and so on to carry out the project research, an extremely close 1(35) 02 N working face goaf three efficient mining of coal, 5 coal layer caving coal face, the summary of extracting a set of extremely close distance coal seam group and efficiently under the goaf mining key technology for the similar working face under the condition of design.
