高水速凝材料在薄煤层开采中的应用

Application of High Water Rapid Hardening Materials in Thin Seam Mining

为了进一步缓解薄煤层工作面的采掘接续紧张,提高煤炭资源的回收率,基于沿空留巷的发展技术,介绍了南屯煤矿3602工作面实施沿空留巷的意义、高水速凝材料的特性及抗压强度、沿空留巷施工时的技术特点、充填工艺及在薄煤层机械化工作面开采中的应用和取得的效果。

In order to further ease the mining thin seam face continued tension,improve the recovery rate of coal resources,based on the development of technology of gob side entry is introduced,Nantun coal mine 3602 working face goaf implemented along the meaning,characteristics and compressive strength of high water rapid hardening materials,technical characteristics,along goaf during construction the filling process and application of surface mining in thin coal seam mechanized and achievements.
