摘要
煤炭是我国经济发展所需的重要能源之一。随着煤矿开采技术的发展。煤矿采掘深度在增加、开采的范围扩大,但是巷道损坏程度有所提高。软岩巷道支护是巷道工程的一个难点。软岩巷道优劣直接影响到煤矿正常生产。从软岩类型、支护原理、原则和类别等方面进行阐述。
Our country is a coal power. Coal is one of the important energy needed for the economic development of our country. With the development of the coal mining technology. Increase in coal mining depth,mining expanded,but roadway damage degree increased.Supporting of soft rock tunnel excavation roadway engineering is a difficult point. Fit and unfit quality directly affect the normal production of coal mine soft rock tunnel excavation. In this paper,from the type of soft rock,supporting principle,elaborates the principles and categories,etc.
