摘　　要：充填采煤是绿色开采的核心,在综合阐述煤矿充填采煤技术发展历史的基础上,介绍了近年来我国综合机械化充填采煤理论及技术取得的重大突破,包括:长壁工作面采充一体化原理、综合机械化固体充填采煤技术、密实充填有效控制岩层运动的目标、充填采煤岩层移动预计的等价采高理论、密实充填采煤岩层移动的解析计算公式和充填采煤岩层移动与地表沉陷实测比较等.指出了研发新型低成本充填材料、提升充填采煤装备自动化水平、建立充填采煤基础理论与相关评价体系、协同充填采煤与地下水环境保护是煤矿充填采煤技术发展的必然趋势.Backfill mining technology, as a crucial part in green mining, have aroused extensive attention all over the world. On the basis of the development history of backfilling technology in coal mine, this paper introduces major breakthroughs of fully mechanized backfilling tech- nology in recent years, which mainly include mining and filling integration principle in longwall face, fully mechanized solid backfill mining technology, the strata movement controlling target in dense backfilling, equivalent mining-height theory in expecting strata movement in backfill- ing mining, analytic calculation formula of strata movement in dense backfilling mining and the comparison between strata movement and surface subsidence measurement in backfilling min- ing. In the end, this paper outlines the prospection of backfilling technology, including develo- ping new type and low costing backfilling materials, promoting automation level of backfilling equipment, establishing basic theory and related evaluation system of backfilling mining, com- bining backfilling mining with groundwater protection, which are the inevitable development trend of backfilling mining technology in coal mine.
