摘要
回采工作面过空巷时会出现明显的矿压问题,煤壁片帮问题严重,甚至还会引发倒架和支架压架等问题,严重阻碍了煤矿的安全生产进程。对此,煤矿企业应结合自身实际情况有效采用顶板支护技术,做好空巷的支护工作,采用有效的支护材料和支护膜袋,以保证矿压的平稳性,顺利通过空巷,获得预期的经济效益和社会效益。
When the working face passes through the goaf,there will be obvious mine pressure problems.The problem of coal wall spalling is serious.It will even lead to problems such as overturning and support pressing,which seriously hinders the safe production process of the coal mine.In this regard,in order to ensure the stability of the mine pressure and smooth passage through the goaf,the coal mine enterprises should adopt the roof support technology effectively,do well in the support of the goaf,and adopt the effective support materials and the support membrane bags,so as to obtain the expected economic and social benefits.
