摘要: 焦家金矿寺庄矿区常有相邻矿脉近似平行排列,曾应用浅孔留矿法、2矿脉单独回采充填法、削壁充填法进行回采,效果均不理想。在生产过程中通过工程技术人员不断摸索,设计出一种灵活、合理的平行相邻排列薄矿体开采方法——相邻矿脉同步回采,并利用2套溜矿井、泄水井联合出矿通风作业,为黄金矿山平行相邻排列薄矿体的高效开采提供了一个崭新的思路。

Abstract: Adjacent veins in Sizhuang mining area of Jiaojia Gold Mine are often seen to be in parallel arrangement to each other.For them, shallow-hole shrinkage stoping, separate cut-fill method of two veins and filling by wall-cutting had been adopted, achieving no ideal results.Through continuous trial and error by technical personnel in production practice, a flexible and rational stoping method for parallelly-lying adjacent narrow veins that is synchronous stoping method of adjacent veins was devised, where two sets of ore passes and drainage wells are used in combination for ore transport and ventilation, providing a fully new thinking for the efficient mining of parallelly-lying adjacent narrow veins in gold mines.
