摘　　要：目的:针对国内某萤石矿采用普通上向水平分层尾砂胶结充填采矿法开采存在机械化程度低、生产效率低、实时在井人数多、生产管理难度大及安全风险高等问题,结合矿体开采技术条件,进行采矿方法的优化。方法:通过对采场结构参数、采准切割工程、回采工艺过程的研究,最终确定了自动化、智能化上向水平分层尾砂胶结充填采矿法,以智能采掘装备替代人工进行开采作业,实现少人甚至无人。结果:生产实践表明:该方法安全、可靠,凿岩、撬毛、铲装和充填环节均实现了5G远程可视化遥控作业,在控顶高度合适的条件下实现了自动定位和自主凿岩作业,作业人员可减少50%以上,取得了良好的经济社会效益。结论:随着我国矿产资源逐步进入深部开采,采矿将面临高地压、高岩爆等恶劣高危作业环境,本文提出的智能化上向水平分层充填法对深地及难采矿体开采具有较好的借鉴参考意义和广泛的推广应用价值。Purpose:In response to the problems of low mechanization,low production efficiency,large number of workers,difficult production management,and high safety risks in the ordinary upward horizontal layered tailings cemented filling mining method used in a domestic fluorite mine,combined with the mining technology conditions of the ore body,the mining method is optimized.Method:Through the study of the structural parameters of the mining site,mining preparation and cutting engineering,and the mining process,an automated and intelligent upward horizontal layered tailings cemented filling mining method was ultimately determined.Intelligent mining equipment was used to replace manual mining operations,achieving few or even no personnel.Result:Production practice shows that this method is safe and reliable,and 5G remote control operation is achieved in the drilling,pilling,shoveling,and filling processes.Automatic positioning and autonomous rock drilling operations are achieved under appropriate control height conditions,and the number of workers can be reduced by more than 50%,achieving good economic and social benefits.Conclusion:With the gradual entry of mineral resources into deep mining in China,mining will face harsh and high-risk working environments such as high ground pressure and high rock bursts.The intelligent upward horizontal layered filling method proposed in this article has good reference significance and wide promotion and application value for deep and difficult to mine ore body mining.
