摘要
本文从狭义顶板离层概念出发 ,详细地阐述了岩层性状的判别原理及方法。通过对各岩层性状相对优劣的判别 ,确定岩层性状较好的岩层 ,然后选择与该岩层位置相协调的锚杆进行巷道顶板支护 ,以期达到更好的锚固效果 ,从而达到保证安全生产 。
The paper detailedly formulates differentiated principle and method of property of stratum from concept of special roof separation. By distinguishing relative properties of every rock strata, we can ascertain the strata whose property is better, and select bolt which coordinate with the location of rock strata to support,so that the better effect of anchorage can be achieved. In this way, it can make sure safety in production and reduce overhauling the laneway or even not overhauling.
