| 摘 要： | Introduction The maintenance of the soft rock roadway is one of main factors that affect the high-production and high-efficiency of mine. The difficult reasons in main-taining this kind of roadway are the large deformation, unstable deformation and different deformation mechanism from other surrounding rock. Because the rock pressure behavior of soft rock engineering and its corresponding control measures are related with rock deformation, so supporting theories and control meth-ods based on t…

| Abstract: | Based on a great number of measured data, the author put forward zonal compressive and tensile deformation mechanism of soft rock around roadway. By using self-supporting capacity of compressive zone and controlling rock deformation of tensile zone, the long bolt or short bolt group supporting form was given for different size of rock compressive zone and tensile zone. Finally, studied on the determining method of rational support parameters of bolting and shotcreting with wire mesh in different support technology. |
