摘要
就洋鸡山金矿露天开采中深孔因爆破安全距离小于“国标”规定的200m安全距离,从理论上提出了特定条件下的看法,并从试验研究中得到了应证。研究成果可为同类型相似条件矿山借鉴与参考。
The safe distance for medium-length hole blasting in Yang-ji-shan Gold Mine was shortened to be less than 200 meters, the distance specified in the State Standards.This paper discusses the approach to this problem, pointing out that the actual condition for blasting in the mine should be taken as a special case. For verification,tests were carried out. The conclusion can be used for reference for other mines with similar blasting conditions.
