摘要
该文通过对新型高水材料巷旁充填工艺的应用与充填后顶底板的移近量与两帮移近量的分析得到,水灰比(W/C)=1.8:1下所构筑的巷旁充填带能满足采面顶板矿压活动要求。现场工业性试验表明,该项技术的应用是成功而有效的,此种沿空留巷的方法具有较高的实用和推广价值。
By applying the technology of new high-water material for road-side filling and analyzing the nearer quantity of top floor and two sides,the paper concludes that when the water / coal = 1. 8: 1,the road-side filling bands can satisfy the mine pressure activity of the roof of the exploitation working surface. The results of industrial test and field measurement show that the technique is applied and the gob-side entry retailing method has relatively high value of practical and promotion.
