综放孤岛工作面顺槽锚固技术研究

Anchorage Technique of Crossheading at Island Coal Face with Fully Mechanized Caving

通过对唐安煤矿3403孤岛面顶底板岩层矿物成分及其崩解性的测定,应用以巷道围岩稳定性分类为基础的工程类比法,得出了孤岛面顺槽的支护方案与相关技术参数,并对锚固效果进行了数值模拟,结果表明所设计的锚固参数是可行的。

By determination of mineral components of 3403 island coal face roof and floor rock and its disintegration,with the application of engineering analogy method based on stability classification of drift surroundings, the supporting scheme and relative technique parameters of island coalface erossheading were obtained. Numerical simulation of anchorage effect was conducted. The result showed that the designed anchoring parameters was feasible.
