摘要
通过研究,实现矿井在井下直接利用原煤中的矸石作为巷旁充填材料中的主要骨料进行充填材料的井下制备,整套工艺和设备系统机械化程度高,可靠性好,产量能够满足沿空留巷充填需要。
Through the study, directly using the gangue generated during mining raw coal in underground as the main aggregate roadside packing materials, and prepare the filling materials, the equipment system and the whole process has the higher degree of mechanization, the good reliability, can satisfy the need of gob filling.
