摘要
为保障矿山企业可持续、高质量发展,以贵州某地下矿山缓倾斜矿体开采为例,结合矿区工程概况、开采技术条件及矿体赋存特征,提出了机械化分条充填采矿法、掘进机进路充填采矿法和机械化上向水平分层充填采矿法3种精细化开采方法。通过现场工业试验,3种采矿方法均取得了显著的经济效益,能达到矿区安全高效、低贫损开采的最终目标,为矿区缓倾斜矿体精细化开采积累了宝贵经验,可为国内外类似矿体开采提供参考。
In order to ensure the sustainable and high-quality development of mining enterprises,taking the mining of a gently inclined orebodies in an underground mine in Guizhou Province as an example,combined with the engineering situation of the mining area,mining technical conditions,and changes in the shape of the orebodies,three refined mining schemes were proposed for the orebodies under different occurrence conditions,which were mechanized strip filling mining method,tunnelboring machine access filling mining method,and mechanized upward horizontal slicing filling mining method.Through field industrial experiments,the three mining methods obtained remarkable economic benefits,which can achieve the ultimate goal of safe,efficient,and low depleted mining in the mining area.This accumulated valuable experience for the refined mining of gently inclined orebodies in the mining area,and provided reference for the similar orebody mining in the domestic and overseas.
