RESEARCH PROGRESS OF SOFT ROCK ENGINEERING GEOMECHANICS IN CHINA COAL MINE

在中国煤矿软岩工程地质力学的研究中 ,作者指出了国际岩石力学学会关于软岩定义的缺陷 ,提出了新的软岩定义和分类 ,并论述了软岩的变形力学机制、软化状态方程、软岩巷道支护理论、支护荷载的确定以及软岩工程地质力学设计方法。可以认为 。

The research development of the soft rock engineering geomechanics in China coal mine is brief discussed in this paper. Firstly, the defects about the definition of soft rock defined by the ISRM are indicated. The new definition and classification of soft rock are brought forward. Based on these, the deformation mechanic of soft rock, the equation of softening state,The determination of loads on the support of the gate,and the design method of soft engineering geomechanics are discussed. It is considerable that the comprehensive system of soft engineering geological mechanism in China coal mine has been formed.
