摘要
大厂105号矿体的埋藏深度在1km左右,目前正在进行开采前期的勘探和设计。通过室内岩爆力学试验,分析了该矿体2种典型岩石的弹性变形能指数Wet、冲击能指数Kcf、岩石脆性系数B和最大储存弹性应变能指标Es。结果表明:围岩无岩爆倾向性,锡矿石具有弱岩爆倾向性。
The burial depth of No.105 Orebody of Dachang is about 1 kin. At present, exploration and design of pre-mining is doing. On the basis of mechanical testing about rockburst, Four factors of elastic energy index Wot, shock energy index Kcfs brittleness index B, and strain energy stored in specimen Es of two typical types of rock in the mine are studied. The results show that the wall rock has no proneness to burst, and the tin ore have weak to medium proneness to burst.
