摘要
以米萝矿为工程实例,采用相似模拟实验研究裂隙发育。实验结果表明:随着工作面的推进,裂隙边界发育成"四边形"结构,此结构存在自相似特性;断层线上方裂隙发育成"三角形"结构;随着工作面的推进裂隙边界角度有所增加,增加到63°左右趋于稳定。
Taking fault fracture to Miluo mine as the engineering example,the similar simulation experiment is used to study fracture development. The experimental results show that: with the working face advancing, fracture into "quadrilateral" structure, and self-similar characteristics; fault fracture of a " triangle" structure;as the working face advancing crack boundary angle increases, increased to 63 degrees is stable.
