摘　　要：为解决神东矿区薄煤层安全高效开采问题,对国内外薄煤层技术装备发展进行了调研,分析了薄煤层开采中面临的巷道断面大、割岩多、掘进效率低、设备适应性差、可靠度低等5大矛盾问题,提出了集薄煤层掘进、切顶成巷、工作面优化布置于一体的巷道布置方案,解决了薄煤层万吨掘进率高、掘进效率低的难题。在分析目前主流的滚筒采煤机、刨煤机采煤技术装备优劣的基础上,提出了采煤装备方案。等高式采煤机机身短、装煤效果好、截割能力大、煤厚适应性好,集滚筒采煤机、刨煤机两者优势于一身,可在巷道内远程控制和检修,破解了薄煤层设备检修难题。通过对波兰矿井的应用实践和神东矿区补连塔矿开采方案的技术经济分析可知,等高式采煤机及配套装备可实现月产12.4万t,年产150万t的高产量,为国内外薄煤层的安全高效开采提供了有益参考。In order to solve the problems of safe efficient mining of thin coal seam at Shendong Mining Area,the domestic and abroad technology and equipment development was reviewed.By analysis of five contradictions such as large tunnel size,more rock-cutting,low efficiency,poor adaptability,low reliability in the thin coal seam mining,a set of thin coal seam excavating,roof-cutting and gateway retained methods,the optimized layout solutions were put forward,which solved the problem of high tunneling rate and low tunneling efficiency.On the basis of current mainstream drum shearers and coal ploughs analysis,the equal hight shearer solutions charactered by short equipment body,efficient loading system,large cutting ability,good adaptability to coal thickness were proposed.Remote control and maintenance at gateway solved the problem of thin seam equipment maintenance.By application practices of Polish Mine and technical and economic analysis of Bulianta Coal Mine mining plan,a good result with output of 124 kilotons per month,1.5 million tons per year was obtained,which could provide the beneficial reference for the domestic and abroad safety and efficient mining of thin coal seam.
