| 摘 要： | 冬瓜山矿的矿体埋深大 ,因而存在高应力 ,并且各向应力不均衡。为了指导将来冬瓜山矿的爆破优化工作 ,利用自行改造的加载设备和动光弹模拟试验装置 ,研究了不同高应力条件下的介质爆破特性。研究表明 ,介质在高应力条件下其强度有所增大 ,因此爆破时应适当增加炸药单耗

| Abstract: | There are high and uneven stresses in the orebody of Dongguashan Mine due to its deep occurrence. In order to guide the future blasting optimization of Dongguashan Mine, the blasting characteristics of the medium under various high stresses are studied by use of reformed loading device and dynamic holophotoelastic modelling. The result of the study has shown that the strength of the medium under high stress conditions is increased with the result that the specific charge would be raised. |
