blasting efficiency
Examples
- Study and practice of raising explosive efficiency in hard rock
提高硬岩巷道爆破效率的研究与实践 - Test and study on increasing the blasting efficiency of underhand cutting and filling method in hexagon stope in longshou mine
提高龙首矿下向六角形进路式采矿爆破效率试验研究 - In the conglomerate tunnel excavation , the semi - diamond shape can obtain high explosion rate , and the rate is up to 85 %
对于砾岩岩石巷道掘进，采用似菱形掏槽形式其爆破效果良好，爆破效率达到85 %以上。 - The main advantage is depressing the explosive quantity and minishing the destroying to the construction foundation . meanwhile , which can improve the blasting effect , made the rock fragment more uniformly , and improve the blasting efficiency
它的主要优点是可降低炸药单耗，减小对建基面的破坏；改善爆破质量，使破碎块度更加均匀，从而提高爆破效率。 - As to the basalt rock tunnel excavation , the gronlund shape is alright , the second shape is wedge - pentagon shape and the diamond shape is unsuited for basalt rock . through the analysis of experimental data and the results of explosion , the explosion rate is up to 85 %
对于玄武岩通过实验结果和数据统计分析，得到gronlund (即变五星)掏槽比较适合于玄武岩岩石巷道掘进，其次是楔形+五星掏槽，而菱形掏槽在玄武岩中不适宜， gronlund (即变五星)掏槽形式其爆破效率达到85 %以上。
