为改善德兴露天铜矿的矿岩爆破质量,提高矿山生产效益,长沙矿山研究院、德兴铜矿及南昌有色冶金设计院、自1979年起对该矿的爆破技术进行了研究,研究结果于1982年12月通过了技术鉴定。研究中根据德兴铜矿的矿岩特征,完成了45次室内模拟试验、96次现场小型试验及10次工业试验。按其中9次工业试验的统计,爆破孔数总计549个,爆区面积为15107米~2,
In order to improve the blasting quality of Dexing open-pit copper mine and improve the mine production efficiency, Changsha Mining Research Institute, Dexing Copper Mine and Nanchang Nonferrous Metallurgical Design Institute have studied the blasting technology of the mine since 1979, and the results In December 1982 passed the technical appraisal. According to the characteristics of ore and rock in Dexing Copper Mine, 45 in-house simulation tests, 96 field small-scale tests and 10 industrial tests were completed in the study. According to the statistics of 9 industrial experiments, the number of blasting holes totaled 549 and the area of blasting area was 15107m ~ 2,
