| 中文摘要: |
| 老挝华潘省香科菱镁矿班怒矿段矿体呈脉状产于断层旁侧的强烈构造变形带中,矿脉厚度为毫米级、厘米级、十余厘米。矿脉反山坡倾斜、倾角较陡。地表探矿工程多采用探槽、剥土,部分地段使用过浅井。编录中以米为单位,进行菱镁矿脉体积含量统计和线比例关系的测算。与化学基本分析对比,菱镁矿脉体积含量统计结果更能准确地反映菱镁矿石含量,可作为圈定矿体、划分矿石品级、进行资源/储量估算的依据。此项工作为班怒矿段资源/储量核实项目的创新,也适用于矿体呈脉状产出、无需采用复杂选矿工艺的各类矿床,有明显的推广应用价值。 |
| 英文摘要: |
| The ore body of the Banyu Mine Section of Xiangke Magnesite in Huapan Province, Laos, is veined in the strong tectonic deformation zone on the side of the fault, with thickness of millimeter, centimeter and ten centimeters. The slope of the vein is steep and the inclination angle is steep. Surface exploration projects mostly use trenching and stripping, and shallow wells are used in some sections. In the catalogue, the volumetric statistics of the magnesite veins and the linear proportional relationship are measured in meters. Compared with the results of chemical basic analysis, the statistical results of magnesite vein volume content can more accurately reflect the magnesite ore content, which can be used as a delineated ore body, which divides the ore grade and calculates the resource/reserve. This work is an innovation of the resource/reserve verification project of the Banrong Mine Section. It is also applicable to all kinds of deposits with ore-like ore-like output and no need for complex mineral processing. It has obvious promotion and application value. |
