摘要
从非机掘巷道工作面的实际情况入手,通过介绍顶板过破碎带时的安全支护技术,提出了掘进工作面过破碎带时顶板支护的技术优化措施,希望对中国煤矿的安全生产起到一些借鉴作用。
Starting from the practical situation of non-machine tunneling face, by introducing the safe support technology used at the time while the roof is passing through fracture zone, proposes the technical optimization measures of roof support for tunneling face though fracture zone, hoping to provide some references for the safety production of coal mines in China.
