摘要
“三下压煤”开采是煤矿开采中面临的难题,而充填开采因其实施安全、生态友好、废物利用等多重优点,在全国各矿区得到了快速发展,煤矿充填用材料的研究与应用越来越受到研究者的重视。系统介绍了我国煤矿充填用材料的研究现状、制备方法及设备等方面的特点,阐述了在矸式充填、超高水充填、膏体充填、泡沫充填等充填方式下应用充填材料的研究现状,分析了充填材料应用的难点和展望。
Coal seam mining under buildings,railways and water bodies is a difficult problem in coal mining.Because of its implementation safety,ecological friendliness,waste utilization and other advantages,filling mining has been rapidly developed in many mining areas in China,and thus the research and application of filling materials in coal mines have been paid more and more attention to by researchers.The paper systematically introduces the research status,preparation methods and equipment characteristics of filling materials used in coal mines and expounds on the research status of filling materials used in gangue backfilling,super-high water backfilling,paste backfilling and foam backfilling etc..Finally,the paper discusses the difficulties and prospects in filling material application.
