六苴矿床急倾斜采矿方法比选

Liuju deposit steep mining method selection

六苴镇位于云南省大姚县北部,界内拥有较丰富的矿产资源,其中以铜矿资源最为丰富。近年来,随着六苴矿床开采的不断深入,矿体走向变短、倾角变陡;原来使用的普通全面法、有底柱分段空场嗣后充填法和沿走向分段空场嗣后充填法在900m~990m急倾斜部份已不适用。本文则是结合六苴矿床多年开采实践和探索,通过分析各种急倾斜采矿方法,来探究更加适合六苴矿床的开采方法。

Liu Ju Zhen is located in Dayao County of Yunnan Province in the north, bounds has rich mineral resources, which in copper resources is the most abundant. In recent years, with the continuous deepening of Liuju deposit mining, ore body to shorter, dip angle becoming; the original use of the ordinary comprehensive method, sill pillars piecewise open stope filling method and along strike segmentation of open stope filling method in 900 m to 990 m steeply inclined part is not applicable. This paper is combined with the Liuju deposit exploitation of many years of practice and exploration, through the analysis of all kinds of steeply inclined mining method, to explore more suitable Liuju deposit mining method.
