Control of Blast Damage in Underground Mines

本项目为井下矿井爆破设计提供了实验室和现场指导。该项目的意义在于，爆破是采矿和掘进作业中最常见和最经济的硬岩破碎方法，爆破过程中爆轰引起的动应力产生裂缝，从而导致残余岩石失稳。本项目为爆破专业的学生提供了爆破设计、爆破监测、爆破危害控制等方面的知识和技能。主要设备包括信号处理系统和内窥镜。该奖金将由主要研究者所在机构提供同等数额的奖金。

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.
