摘要
沿空留巷是一项较完善的技术,软岩顶板并留双巷技术,在矿井生产中较少采用。在实际生产过程中,在软岩顶板煤层采煤工作面留双巷解决了通风和瓦斯巷道的难题。就软岩顶板留双巷的方法和有关技术问题进行论述,对留双巷的问题提出解决方法。
Retaining roadway along goaf is a better technology,soft rock roof and double-lane technology is less used in mine production.In the actual production process,for an effective attempt at soft rock roof seam coal face two-lane left to solve the problem of ventilation and gas roadway.Methods discussed two-lanes left soft roof and related technical issues,the issues raised remain dual lane solution.
