巷道掘进支护方案设计

The Design of Support Scheme during the Roadway Tunnelling

本文通过某煤矿在巷道开挖前期进行巷道支护的设计计算对煤矿支护进行了阐述,同时在支护完成后增加了矿压监测措施,两种手段结合,共同构成了巷道的支护系统。该支护系统在煤矿掘进过程中保证了煤矿的安全生产,有效地防治了煤矿冒顶事故,具有现实意义,值得推广。

According to the support design and calculation of roadway before tunnelling of a certain coal mine this thesis illustrate the coalmine support,after support work add supervision measures of mine pressure at the same time,the combination of two measures make up thesupport system of roadway.This system ensure the safe production of coal mine during the tunnelling procedure,and effectively prevent the rooffall accident of coal mine,which has practical significance and promotional value.
