China is rich in coal resources. In most cases, coal resources are obtained through the way of mining. In the process of mining, it is necessary to control the application of mining technology, otherwise it will easily cause damage to the geological structure. With the increasing demand of social resources in recent years, shallow mining has been unable to meet the needs of the society, while deep mining is facing the problem of soft rock layer, which can not guarantee the stability and safety. Based on this, this paper will focus on the coal mine soft rock roadway support technology.
