摘　　要：对我国大型露天煤矿近些年出现并引起重视的生产工艺和技术问题进行了分析研究.认为将土地复垦纳入采矿工程中来实现"边开采、边复垦"的一体化作业,以缩短复垦周期和提高土地复垦率是我国大型露天煤矿区今后开展地土复垦工作的关键;采用地下台阶式开采法回采露天矿端帮煤可大大提高煤炭资源回收率和矿山经济效益;我国已经或将要开发的适宜露开天采的大型、特大型煤矿中,拉斗铲倒剥离工艺应用的条件已经具备,在这些矿区的设计与建设过程中,应对该工艺给予重视,大胆引用.Some production-technical problems in Chinese large surface coal mines were analyzed. The integration of mining and reclamation operations can shorten the period for land rehabilitation and increase the reclamation ratio of the land, being a key factor for reclamation work in large surface coal mining areas. To recover the remainder coal in the side slope walls of surface mine by use of underground coal winning method can increase coal recovery rate and mine economic effect. Open cast method by dragline stripping technology is suitable for a number of large coal fields which are favorable for surface mining. Therefore, great attention should be taken in design and construction work for future surface mine development.
