基于尹格庄金矿开采实践的厚大缓倾斜破碎矿体开采技术研究

Study on the mining technology of gently inclined thick broken ore body based on the mining practice in Yingezhuang gold mine

尹格庄金矿矿体厚大多变,上盘破碎矿体回采困难。尹格庄金矿经过多年的科研及生产实践,逐渐形成了上盘厚大破碎矿体采用无底柱分段崩落采矿法、下盘和两翼多变矿体采用盘区机械化上向分层充填采矿法回采相结合的高效机械化综合采矿方案。详细介绍了采矿方法采场结构参数、回采工艺过程及主要技术经济指标,为类似矿体开采积累了经验。

Yingezhuang ore body is thick and changeable,with its hanging side tattered that is difficult to recover. Thick hanging orebody being stoped by sublevel caving method with no sill pillars, and footwall and changeable wings being stoped by mechanized upwards cut-and-fill stoping, come into being from years of research and practice of mine production, which is an efficient mechanized mining design. The paper elaborates the structural parameters of the rain- ing method,process of the recovery and main economic tions. indexes, accumulating experience for similar mining conditions.
