| 摘 要： | 在对开阳磷矿砂岩自然风干和饱水状态下静力学特性试验研究的基础上,探讨了水对岩爆防治的静力学机制。饱水砂岩静载试验表明较硬岩石遇水后静态强度下降,变形量增大,岩体积聚弹性能的能力下降;三心拱巷道围岩遇水软化后,支承压力峰值应力明显减少,峰值位置向岩体深部转移,这样能有效降低岩爆发生的机率和等级。

| Abstract: | Based on the compressive experiment of statics properties of air-dried and water-saturated sandstone from Kaiyang Phosphate Mine,the statics mechanism of rock-burst prevention with water is discussed.The static load experiment of water-saturated sandstone showed that water can decrease its static strength and its capability of accumulating elastic energy and can increase its deformation.With surrounding rock of three-centered arch roadway softened by water,its peak value of abutment pressure reduces obviously and transfers to deep place,so all of these can effectively decrease the probability and level of rockburst occurrence. |
