高水速凝材料充填护巷技术

Application of High Water Quick-setting Material in Filling and Protection of Tunnel

对埋藏深、地应力大、顶板破碎的多煤层开采,利用高水速凝材料作巷旁支护,进行沿空留巷;对不同的巷道在时间、空间、方式上采用不同的沿空留巷方法进行维护,得出实际应用的一些结论。

Multi-seam mining of deep-buried,great stress,broken roof was using high water quick-setting materials in tunnel sides support and protection,and tunnel stay along gob was made,different gob methods were maintained in terms of a different time and space and the way of different tunnels,and some conclusions in practical application were investigated in this paper.
