中深部磷矿体开采设计探讨

Approach for design of medium and great depths of phosphate orebody

结合近几年中深部矿体开采的设计工作实践,探讨了中深部矿体开采问题,主要包括:统一规划分区、分期开采、合理确定开采顺序;首选充填采矿法;提高装备水平,实现高效率、规模化开采,促进矿山现代化;优化通风系统,推广多级机站通风。

Issues about mining of the medium and great depths of orebody are discussed in combination with the practice of design work of the medium and great depths of orebody in recent years.They mainly include subsectional and periodical mining in unified planning,proper determination of mining sequence,preferred back-filling mining method,upgrade of equipment level,realization of high efficiency,large-scale mining,advancing mine modernization,ventilation system optimization,popularizing ventilation in multistage machine station.
