采矿方法中伪倾斜布置在缓倾斜薄矿体中的应用

Application of false inclined arrangement in gently inclined thin ore body

为了提高开采缓倾斜薄矿体的机械化程度和矿山产能,对缓倾斜薄矿体开采方法以及铲运机运输巷道的布置方式进行研究,利用空间几何和三角函数的关系,分析了铲运机运输巷道在采场中伪倾斜布置形式。针对国内某铁矿山缓倾斜薄矿体的开采,在伪倾斜布置形式分析的基础上,得出适合于某铁矿开采的最优采矿方法,加大了采场的生产能力,提升了矿山装备水平,提高了矿山生产的安全性。

In order to improve the level of mechanization of the gently inclined thin ore body and the mine production capacity,the mining method of the gently inclined thin ore body and the scraper transportation roadway layout were studied. Based on the relationship between the spatial geometry and trigonometry,the false-inclined arrangement of scraper transportation roadway in stope was analyzed. In view of the mining of gently inclined thin ore body of a domestic iron ore mine,based on the analysis of the false inclined arrangement,the optimal mining method suitable for this mine was obtained. The stope production capacity was increased,the mining equipment level was promoted and the safety of mine production was improved.
