摘要
基于浅部大采高超长工作面应用的成功经验,在深部大采高超长工作面回采实践的基础上,分析了深部大采高超长工作面回采可能遇到的矿压显现、煤壁片帮、巷道变形和超前支护问题。分析表明,液压支架支护技术能够满足深部大采高超长工作面回采要求,煤壁片帮、巷道大变形与超前支护的适应性仍需加强研究。
Based on the successful experience of ultra long mining face in shallow fully mechanized mining face and the practical problem of ultra long mining face in deep fully mechanized mining face,analyzed the underground pressure control problem, coal wall spalling control issues, roadway deformation and advance support issues. Analysis showed that the hydraulic support technology meet the current requirements, other two factors were needed to be strengthened research.
