Then the failure mode and the coefficient of stability of the displaceable blocks were studied respectively.

主要内容包括：①在野外地质调查基础上，通过统计分析得到地下厂区结构面的优势方位；对结构面工程地质特性进行了分析；根据结构面的空间组合关系，搜索出可能在主厂房洞室的顶拱和边墙部位出露的块体，并分析了各块体的可能滑移方式及其稳定性系数。

And the main contents of this dissertation are:(1)The engineering geological features of discontinuities in surrounding rock mass were analyzed on the basis of field geological survey and the preferred orientation of the main discontinuities were derived. Then the displaceable blocks distributing on the roof and sidewalls of main chamber were searched out taking the intersecting relationship of discontinuities into consideration. Then the failure mode and the coefficient of stability of the displaceable blocks were studied respectively.
