渗流对坚硬复合岩体巷道环境断裂失稳影响分析

EFFECT OF SEEPAGE FLOW ON UNSTABILITY OR BREAK OF HARD ROCK STOPES

摘要: 本文在借鉴孔隙介质渗流过程的细观实验与理论研究的基础上,从宏观上分析了渗流对复合坚硬岩石材料支护的巷道环境断裂失稳的影响,提出相应工程治理措施,这对以坚硬岩石复合材料支护为骨架的锚注支护塌陷区是一个大胆的尝试。

Abstract: Seepage flow always causes unstability or break of underground hard rock stopes.The appropriate countermeasures against the negative effect of seepage flow are introduced and analysed.These measures are brave attempt for underground stopes having danger of unstability or break caused by seepage flow.
