浅谈大宝山铜硫矿床二级矿量管理

Discussion on the Management of Ore Quantity of Grade Two in Dabaoshan Copper Sulphur Deposit

大宝山铜硫矿床经过多次地质运动而形成,矿石种类繁多,主要为磁黄铁矿型铜矿、黄铁矿型铜矿、辉铜矿、氧化矿等,而每个类型的铜硫矿石又有粗中细粒之分,这些都会影响铜硫矿石的选矿指标(如回收率).文章通过生勘资料、潜孔资料及其掌子面实际资料对采场二级矿量(开拓矿量、备采矿量)进行计算,确定各种矿石类型的矿量及其分布情况,为开采设计提供依据,编制月度、季度、年度计划,及时了解生产过程中对矿产资源利用情况及矿石贫化、损失率的计算和管理,动态掌握二级矿量的开采情况,最大化利用矿产资源,保持选矿指标优良,从而保持矿山持续均衡地生产.

There is a great variety- of ores in Dabaoshan Copper Sulphur Deposit which had formed after many times of geo- logical movements, mainly the pyrrhotite copper ore, pyrite copper ore, cyprite, oxide bearing ore and so on. Each type of copper sulphur can he classified into three grades according to its granularity. These factors will impact the separation in- dice of copper sulphur ore. In order to provide the base for designing the mining plan, working out the monthly plan, sea- sonal plan and yearly plan, and understanding the ore source status in production and the management and calculation on the ore dilution and loss in time, mastering the mining status of ore quantity- of grade 2, utilizing the ore source at its maxi- mization, and keeping the good separation indice maintaining the sustainable and balanced production of the mine, the quantity- of different types of ores and its distribution have been determined through the calculation on the ore quantity- of grade 2 with the survey data, submersible data and actual data on the face of the pahn.
