Research on the technology of soft rock roadway

Soft rock roadway has the property of large loose circle, low strength. In order to keep the roadway stable and meet the need of normal production, it is necessary to adopt reasonable and feasible supporting form and scheme to fit and improve the characteristic of surrounding rock, gaining the effect with feasible technology and reasonable economy. In this paper, in the base of analyzing the deformation and failure property of soft rock roadway, the three-dimensions coupling control technology adaptability to the soft rock roadway. The three-dimension coupling control scheme and craft were designed in the theory of three-dimension coupling-control, and gain better effect in fact engineering.
