我矿属于不稳岩矿复杂Ⅸ类型矿床。此类矿床的矿体围岩一般不稳固,矿体一般也不稳固,矿体倾角一般为20～35°、厚度一般为5.0～6.0米,矿石品位一般较高,属于富矿体。几年以来,我矿对此矿床类型,开展了多种采矿方法的研究试验工作。通过反复实践证明,现行水平分层崩落法是我矿此类矿床行之有效的采矿方法,并初步摸索出一些经验和教训,现简述如后,以供相类似矿山在作采矿方法试验应用时作参考。 Mine belongs to the unstable rock complex Ⅸ type deposits. The ore bodies of this type of deposit are generally unstable in rock mass, and the ore bodies are generally not stable. The ore body dip is generally 20-35 °, and the thickness is generally 5.0-6.0 meters. The grade of ore is generally high and belongs to the ore-rich body. Over the past few years, I mine on the type of deposit, conducted a variety of mining methods of research and experimental work. Through repeated practice, it has been proved that the current horizontal caving method is an effective mining method for such deposits in our mine and some initial experiences and lessons have been found. The present situation is briefly described as follows for the similar mining operation reference.
