近距离煤层掘进面顶板控制分析

Roof Control Analysis of Driving Face in Close Distance Coal Seams

复杂地质条件下的巷道掘进作业安全是矿井生产安全中的关键环节之一,以此为着手点,针对近距离煤层掘进面顶板控制开展研究。结合工程实际,从巷道掘进、采掘连续、巷道支护等多个角度综合阐述如何实现特近距离煤层下层煤巷道的安全掘进,希望能够为其他矿井相似工程的有效开展提供借鉴与参考。

The safety of roadway tunneling under complex geological conditions is one of the key links in mine production safety. Taking this as the starting point, this paper studied the roof control of the driving face in the close distance coal seams. Based on the engineering practice, it expounded comprehensively how to realize the safe tunneling of the under seam coal roadway of extra close distance coal seams from the aspects of roadway driving, continuous mining and roadway support, etc., in the hope of provi-ding reference for the effective implementation of similar projects in other mines.
