In order to research the supporting methods for deep rock roadway with broken and soft surrounding rock in coal mines

this article analyzed the deformation pattern of the deep rock roadway basing on the engineering background of level -780 m south wing rail roadway of Guqiao Coal Mine

Huainan mining area. Comparing with the shallow rock roadway

the difficulties as well as methods in supporting deep rock roadway were analyzed; and afterwards

Sub-step supporting method and optimized supporting method for south wing rail roadway of Guqiao Coal Mine were raised. Monitoring data show that sub-step supporting method is successfully used in the level -780 m south wing rail roadway of Guqiao Coal Mine. The following ideas were raised

deep rock roadway is affected by multiple factors

such as ground pressure and physical features of the rock mess. Supporting methods should consider geological conditions and make all of the supporting measures to achieve effective integration so as to enhance the self-supporting capability of the surrounding rock
