This project provides laboratory and field-oriented instructions in underground mine blast design. This project significance lies in the fact that blasting is the most common and cost-effective method of breaking hard rock in mining and tunneling operations and during blasting dynamic stresses induced by the detonations create cracks thereby resulting in instabilities in the remaining rock. This project provides the students studying blasting techniques the knowledge and skill to design and monitor blasts and recommend measures to control blast damage. The major items of equipment include a signal processing system and a borescope. This award is being matched by an equal amount from the principal investigator's institution.

该项目为地下矿山的爆破设计提供实验室和现场指导。这一工程意义在于，爆破是采矿和隧道施工中最常见和最经济的破碎坚硬岩石的方法，在爆破过程中，爆炸产生的动应力会产生裂隙，从而导致剩余岩石的不稳定。该项目为学习爆破技术的学生提供了设计和监测爆炸并建议控制爆炸破坏的措施的知识和技能。主要设备包括一个信号处理系统和一个钻孔探测仪。这一奖励由首席调查员所在机构提供的等额奖金相匹配。
