摘要
巷道采掘的过程中,随着开采的深度增加,底鼓的现象也成为表现突出的现象,也严重影响着施工的安全和施工工期,本文依据现场的工程实际,通过对软岩巷道的失稳机理和比较两种支护方式下的围岩的应力和变形,从而选择出相对来说具有较好满足现场需求的支护方式,进而为软岩巷道的支护开拓了新的途径。
In the process of tunnel excavation,along with the mining depth increasing,the bass drum phenomenon has become a prominent phenomenon, also seriously affect the construction safety and construction time limit for a project,according to the scene of the engineering practice,through the instability mechanism of soft rock roadways and comparing the two kinds of supporting mode of stress and deformation of surrounding rock,so as to choose the relatively better meet the demand of the supporting method,and then opened a new way for soft rock supporting.
