摘要: 西石门铁矿南区受浅部采场盗采严重、出矿品位低、产能低以及深部矿体开采难度增大、开拓滞缓影响,生产中出现产量任务紧、原矿品位低、过渡衔接困难等问题。为此,在分析岩体可冒性的基础上,提出上部贫矿与下部富矿平行开采的方案,并通过改进回采方法,达到提高矿石生产能力和实现贫富兼采的目的。此外,针对深部开拓滞后问题,提出主体工程分段同时施工的技术措施,以加快下位工作面开拓进度。

关键词: 岩体可冒性, 贫富兼采, 快速开拓

Abstract: Affected by illegal mining, waste rock mixed, low productivity of ore, the increasing difficulty mining of deep ore body exploitation and slow development, the southern district of Xishimen has some production problems, such as great production pressure, low grade of raw ore, difficult to transition.Therefore, according to the analysis of rock caving feasibility, a new scheme that the upper low grade ore and the lower high grade ore are exploited simultaneously is proposed.The mining technique also improves the production capacity and realizes the objective of the simultaneous exploitation of low and high-grade ore by improving the mining method.In addition, the technical measure of excavating in sublevels simultaneous is proposed to accelerate the development process in deep part.

Key words: Rock caving feasibility, Simultaneous exploitation of low and high-grade ore, High-speed development
