昆士兰大学的一项研究，在应付地下矿山巷道垮落引起的破坏方面，改善了安全和节约了数以百万元的损失。采矿工程界的国际权威B．布雷迪（BarryBrady）教授和他的研究小组正在开发一种计算机模型，用来分析生产爆破对岩石性状变化的影响。地下硬岩矿山的作业巷道经常承受附近爆
A study by the University of Queensland has improved safety and saved millions of dollars in damage caused by the collapse of tunnels in underground mines. International authority in mining engineering Professor Barry Brady and his team are developing a computer model to analyze the impact of production blasting on changes in rock properties. Underground hard rock mine roadway often suffer near the explosion
