摘　　要：为解决综采工作面煤层开采时所面临的矿压现象剧烈、顶板管理困难、单产率低等问题,以实践生产为例,在对其地质、煤层以及顶底板条件分析的基础上,对开采方案进行优选;同时,参照103#和105#工作面开采经验对102#综采工作面煤层的回采工艺进行设计;最后,从社会和经济效益两方面验证了开采方案和回采工艺的应用效果。In order to solve the problems such as severe ground pressure,difficult roof management and low yield per unit area faced by the coal mining in the fully mechanized working face,taking practical production as an example,based on the analysis of its geology,coal seams,roof and floor conditions,the mining scheme is optimized.Meanwhile,based on the mining experience of the 103#and 105#working faces,the mining process of the 102#fully mechanized working face coal seam is designed.Finally,the application effects of the mining plan and mining process were verified from both social and economic benefits.
