摘要
为了实现煤巷的快速掘进,促进煤矿的高效生产,对提高煤巷掘进速度的技术进行了总结,并结合具体工程案例,采用优化支护工艺和参数的技术来提高煤巷掘进速度。结果表明,支护工艺和参数优化后,巷道顶板和两帮变形量大大减小,有利于煤巷的安全快速掘进,对同类工程具有借鉴意义。
In order to realize the rapid driving of coal roadway and promote the efficient production of coal mine,this paper summarized the technologies of improving the driving speed of coal roadway,and combined with specific engineering cases,adopted the technology of optimizing support technology and parameters to improve the driving speed of coal roadway.The results show that after the optimization of support technology and parameters,the deformation of roadway roof and two sides is greatly reduced,which is conducive to the safe and rapid driving of coal roadway,and has reference significance for similar projects.
