| Abstract: | Raising bench height is an important problem concerning the development of production and technique in the open-pit metal mines in the country. Proceeding from reasonable utilization of explosive energy, the paper discusses the relation between the ratio of stemming height/bench height, and loading height. The influence of the ratio of hole spacing/burden on blasting resulting in the condition of high bench is analysed. The reasonable loading structure and rea ming blasting are expounded. |
