落凼矿床深部矿体开采技术研究

为了解决落凼矿床深部矿体合理规划、经济开采、安全生产的问题,根据矿体赋存条件,对开采方式、地下开拓系统、采矿方法、空区处理和投资效益分析等内容进行深入的优化和研究。结果表明,所选择的露—坑联合开采方式、平硐—斜井—竖井联合开拓系统、有底部结构分段空场嗣后联合充填无间柱回采方案,具有安全、可靠和技术经济指标先进等优点,对今后的开发具有一定的指导意义。

luodang deposit deep ore body mining technology research

In order to solve rational planning,economic exploitation,production safety problems of the deep orebody in Luodang Deposit,we focus on the optimization and research of the conditions of ore body,mining methods,underground development system,mining methods,goaf processing and investment-benefit analysis.The results show that the selection of the open-pit combined mining mode,adit-inclined shaft-shaft combined development system,and open stope filling non-pillar sublevel combined mining scheme with bottom structure is safe and reliable,which has advanced technical and economic indicators.It has certain guiding significance for the future development.
