摘要
通过对孤岛工作面上覆岩层结构特点进行研究分析,提出了"注浆加固+U型钢支架+锚杆"联合支护技术,对孤岛工作面回采巷道进行有效的支护,控制巷道变形。应用结果表明,该支护技术可以有效减小巷道变形,取得良好的支护效果,保障煤矿安全生产。
Through the research and analysis of structure characteristics of overburden rock on isolated working face,combined supporting technology,including grouting reinforcement+type steel support and grouting anchor,was proposed in the paper,whose purpose was to achieve good supporting effects,and maintain the stability of roadway.Application results show that the supporting technology can effectively reduce the deformation of the tunnel,has good supporting effect.
