矿山生产探矿的主要任务是运用一整套多快好省的勘探方法,探明供开采的矿量.为此,要在矿床地质综合研究及勘探工程综合应用的基础上,进行总体设计.采用坑探和岩芯钻探进行综合勘探是符合我国金属矿山地下探矿和开采的具体要求的.经过几年的试验和生产实践证明,用人造金刚石小口径岩芯钻探作为矿山辅助探矿手段比完全采用坑道掘进探矿具有一系列优点: 1.矿体揭露点多,由30米加密控制到10～15米,有利于控制矿体边界、降低矿石损失和贫化. 2.平均台班进尺5米以上,平均时效1.87米,比坑探提高四、五倍,从而加快勘探进度. 3.岩(矿)芯采取率平均80%以上,有时达
The main task of mine production prospecting is to use a set of more and more favorable exploration methods to identify the amount of ore for mining.To this end, in the comprehensive geological prospecting and exploration engineering application based on the overall design.Using pit Exploration and exploration of core drilling is in line with the specific requirements of underground exploration and mining of metal mines in China.After several years of experiments and production practices have proved that the use of artificial diamond small diameter core drilling as a subsidiary of prospecting means of mining than the full use of tunneling Prospecting has a series of advantages: 1.The ore body exposes a lot of points, controlled by 30 meters encryption to 10 ~ 15 meters, help to control the ore body boundary, reduce ore loss and depletion. Aging 1.87 meters, four or five times higher than pit exploration, thereby accelerating the exploration progress 3. Rock (ore) core take rate average more than 80%, and sometimes up to
