【摘要】 通过对华东某矿区采煤塌陷土地破坏与村庄搬迁赔偿费的统计分析,对煤矿充填开采技术的经济适应性和应用前景进行了探讨.针对传统充填开采成本相对偏高的问题,提出了部分充填开采的概念和3项部分充填开采技术,即采空区膏体条带充填技术、覆岩离层分区隔离注浆充填技术、条带开采冒落区注浆充填技术,分别对其技术原理进行了介绍.更多还原

【Abstract】 Through the statistics and analysis of the compensation for land damage and the expense of village migration induced by mining in a certain mining area of East China,the economical feasibility and the developing prospect of filling method for coal mining have been studied.Because of relative high cost of traditional filling,a new concept of the partial-filling and three technical ways are put forward,including the technologies of partial paste filling in goaf,isolated section-grouting for the overburden bed separation space,and strip mining with caving and grouting of gob area.The mechanism and principle of the partial-filling technical ways are introduced.更多还原
