| 岩体的应力测量包括岩体初始地应力量测和洞室围岩应力量测,是现代岩体力学研究的重要组成部分,可为了解岩体稳定程度提供重要参数,为地下工程开挖提供设计参数.以某铜矿为例,首先测定原岩应力,矿区属中等级别的应力区;再采用光弹应力计监测岩体二次应力,结合观测数据,找出二次应力变化导致采场应力集中的部位,采取措施,使应力局部得到部分释放,再进行施工,以保证生产的安全进行,提高劳动生产率. |
| 英文摘要: |
| The rock mass stress measurement includes the rock mass initial stress gauging and the secondary stress gauging on the wall rock of grotto.It is the important component of the modern rock mechanics research.And it may provide the key parameter for understanding the rock mass stable degree,so as to provide the design variable for the understructure work excavation.Taking the copper mine as an example,first of all,we measured the rock stress.Mine is a medium-stress zone.Then the secondary stress was monitored by the photo-elastic stress gauge;combined with the observation data,we can discover the spot where the secondary stress changes so as to induce the stope stress concentrate,and take measures to release the partial stress.The safety in production can be guaranteed,the productivity of labor can be raised. |
