| Abstract: | Based on the engineering geologic investigation,the laboratory physic*.chemical analysis and the mechanics test,its deformation mechanism and failure mechanism have been studied.According to New Austrian Tynnelling Method,the comprehensive control measures are taken in the light of local conditions.Thus,it has made the complex deformation mechanism into sigle deformation mechanism and the engineering is controlled well.The technology experiments can be used for other instability destruction engineering of the same cases in coal mines. |
