广西大厂铜坑矿坑钻结合勘查的应用效果

Combined application of tunneling and underground drilling techniques for mineral exploration in Tongkeng mine, Dachang, Guangxi

坑探所揭露的地质信息较全,是矿山企业普遍使用的地质勘查手段,但其成本高、速度慢,难以适应大规模生产,尤其是井下掘进产生的炮烟、油烟以及废石中的铅、锌、镉、硫、砷等有害物质,对人体的侵害和环境污染愈显突出。而坑内钻探具有施工灵活、成本低、快速控制矿体等优点,与适当的坑探结合,在矿山生产中能发挥出优越的作用。文章通过勘探设计、面积重合率和储量验证对比,表明坑钻结合探矿的可信度高,经济适用,减少废石出窿,降低了环境污染,有利于绿色矿山的建设。

Tunneling is widely used exploration approach in the mine enterprise because it can reveal the detailed geological information, however, there are many disadvantages by using tunneling method, such as high cost, low speed and hard to meet the mass mining production, especially the environmental and health problems resulted from tunneling like the gun smoke, fumes and harmful materials like zinc, cadmium, sulfur, arsenic and other substances in the waste rock. In the contrast, the underground drilling has the advantages of easy - to - operation, low cost, and fast speed to outline the orebodies. Therefore, the combined application of tunneling and underground drilling will play more roles in mine exploration and mining operation. It is discussed that the combined approach through exploration design, the coincidence rate of areas,and reserves verification, the resuh indicates that the combined technique of tunneling and underground drilling method is reliable, and economically viable; meanwhile it can reduces the waste rock and reduce the environmental pollution, which are beneficial for constructing a green mine.
