| 中文摘要: |
| 东梁金矿床是火山机构引发的环形断裂控制的金矿床,主矿体长1700 m,平均厚度24.72 m,黄金资源储量19.53t,平均品位1.55×10-6,是个中型低品位金矿床,该矿适合按不同厚度分级圈定进行坑采,才能有效控制矿石的贫化率,保证矿石的入选品位,不适合露天开采和常规意义上的坑采。 |
| 英文摘要: |
| The Dongliang gold deposit is an annular fracture-controlled gold deposit caused
by volcanic mechanism.The main orebody is 1700 meters in length, 24-72 meters in thickness. There is about 19-
53 tons of gold metal reserves with the average grade of 1×10-6-55×10-6.It is a medium-sized and
low grade gold deposit which is suitable for tunnel mining according to the delineated orebody by orebody
thickness classification as well as control the mining dilution rate effectively and ensure the valid head ore
grade.It is not suitable for open pit mining operation and the common practical underground mining operation. |
