前言 软岩巷道支护问题是我国某些矿区影响正常生产和建设的关键问题。今后,随着巷道布置的改革,煤层中的大巷将要不断增加,以及随着开采深度的逐年增大,软岩巷道也将逐年增多。因此,解决软岩巷道的合理支护问题对于我国煤炭生产和建设具有重要的意义。本文拟通过近年来的研究和实践体会,介绍几种适用于软岩巷道的支护形式及其施工工艺。
Preface Soft rock roadway support is the key issue affecting the normal production and construction of some mining areas in China. In the future, with the reform of the layout of the roadway, the number of lanes in the coal seam will continue to increase, and as the mining depth increases year by year, the soft rock tunnel will also increase year by year. Therefore, to solve the problem of reasonable support of soft rock roadway is of great significance to the coal production and construction in China. This article intends to introduce several supporting forms suitable for soft rock roadway and its construction technology through the experience and research in recent years.
