隧洞掘进的安全和速率取决于有效爆破。炸药和雷管的选择可能对爆破效率影响较大。印度炸药有限责任公司(IEL)提供能明显提高每次爆破进尺、减少钻爆所需时间和优化每立方米破碎岩石成本的产品和服务。其爆破效率的提高在一些隧洞掘进作业(包括印度喜马偕尔邦的纳思帕贾克里水电工程、不丹的塔拉水电工程、尼泊尔的上帕特科舍工程和其他几个工程)中已经得到证明。阐述了该公司的产品、适用的爆破设计及其在几座工程中的实施情况。
The safety and speed of tunneling depend on the effective blasting. The choice of explosives and detonators may have a greater impact on blasting efficiency. IEL provides products and services that significantly increase the footage per blast, reduce the time required to drill and blast, and optimize the cost per cubic meter of rock crushed. Improved Blasting Efficiency In some tunneling operations (including the Nashpakkali Hydropower Project in Himachal Pradesh, India, the Tara Hydropower Project in Bhutan, the Upper Partkoseh Project in Nepal and several other projects) Has been proved. Describes the company’s products, applicable blasting design and its implementation in several projects.
