Abstract
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.关键词
