摘要
针对采准巷道的垮冒点多发生在与其相交的断层破碎带部位的实际情况 ,通过宏观调查和微观分析的手段 ,掌握了破碎带的空间分布规律和主要组成的矿物成分 ,提出了有效的巷道支护方案并付诸实施 ,取得了良好的加固效果 。
The collapse of stope development in chengchao Iron Mine often take place on the intersection points with fault crush zone.Through macroscopic investigation and microscopic analysis,the spatial distribution regularity and mineral composition of crush zone are ascertained and so the gallery support program is put forward and put into effect.This ensures the gallery the stability.
