摘　　要：以刘庄煤矿171301工作面回采巷道地质条件为工程背景,分析了大采高工作面回采巷道支护的特点和要求,对超大断面回采巷道断面形状、支护参数、超前加强支护形式进行了优化设计,现场实践表明:优化后的支护技术保证了综采面的安全生产,提高了工作效率,降低了生产成本,为大采高综采面快速推进创造了条件。According to the geological conditions of mining roadway in Liuzhuang coal mine 171301 working face, the characteristics and requirements were analyzed for support of mining roadway in working face with large mining height, the design was optimized for the section form, support parameters and the form of advanced strengthen support of super - large section mining roadway. The practices show that, the proposed supporting technology can ensure the safe production of fully mechanized working face, improve work efficiency, reduce production costs, creating the conditions for the rapid advance of large mining height working face.
