摘要
随着矿产资源开发走向深部,充填采矿法将是未来矿山采矿方法的首选。以国内外矿山充填采矿技术的发展历史和应用现状为基础,系统分析了深部矿山高采深、高地应力特点对现有充填采矿技术提出的挑战,详细列举了目前深井充填可能面临的各种问题,并探讨了解决对策;同时结合循环经济和绿色开采,提出矿山充填材料选择应向多元化和无害化方向发展,并指出与充填采矿相关的法律制度亟需制定,充填标准亟待建立,充填理论尚需完善。
With the deep mining of mineral resources,the backfill mining method would be the first choice of mining method in the future.Based on the development history and application status of mine backfill mining technology,the challenges posed by the characteristics of high mining depth and high crustal stress to the existing mine backfill technology were analyzed systematically.What’s more,various kinds of problems in deep mine backfill were put forward and discussed.Combined with circular economy and green mining,the selection of backfill materials shall be harmless and diversified.In addition,the legal system and standard related to mine backfill are urgently needed to be established,and the filling theories still need to be improved.
