摘　　要：索尔库都克铜矿已露天开采多年,为保证矿山可持续性发展,矿山开展了露天转井下开采研究工作。根据索尔库都克铜矿矽卡岩型矿床特性及极坚硬缓倾斜矿体形态,并结合国内外中大型露天矿山转井下成功经验,认为适合的地下采矿方法为空场采矿方法。当矿体厚度小于3 m、倾角小于15°时,采用房柱采矿法回采;当矿体厚度为3~12 m、倾角小于30°时,采用采场斜坡道留柱采矿法回采;当矿体厚度大于12 m、倾角大于30°时,采用分段空场法回采。Sorkuduke copper mine has been open-pit mining for many years.In order to ensure the sustainable development of the mine,the research work of open-pit to underground mining has been carried out.According to the characteristics of skarn type deposit and extremely hard gently inclined orebody shape Sorkuduke Copper Mine,and combined with the successful experience of large and medium-sized open-pit mines in China and abroad,it is considered that the suitable underground mining method is open-pit mining method.When the thickness of the ore body is less than 3 m and the dip angle is less than 15°,the room-pillar mining method is adopted.When the thickness of the ore body is 3~12 m and the dip angle is less than 30°,the pillar-retained mining method of stope ramp is adopted.When the thickness of the ore body is greater than 12 m and the dip angle is greater than 30°,the segmented open-field method is used for mining.
