摘要
全国"三下"压煤达13.7Gt,同时地面堆积的矸石达4.5Gt,如能利用矸石进行充填开采,则既可提高资源回收率,又能节省矸石占地、改善地面环境。当前的技术、经济和社会条件为充填开采创造了有利环境,使充填开采在全国各矿区得到快速发展。文章对当前我国煤矿充填开采方法和应用现状进行了归纳和总结,并对发展前景进行了展望。
At present,coal resource under railway,building and waterbody reaches 13.7Gt in China and waste rock piled on surface reaches 4.5Gt.Applying waste rock to stowing mining can improve resource recovery ratio and save occupation land of waste rock and perfect surface environment.Current technology,economic and society condition create favorable environment for stowing mining and make it developed fast in China.This paper concluded stowing mining method and its application status and look far ahead its develop prospect.
