Improving mining activity outcomes through impedance imaging

电子雷管的发展为现代爆破应用创造了很大程度的灵活性。雷管的时间可以精确地改变，以便根据岩石和土壤的性质精确地优化爆炸模式。它们也可以在爆炸放置和加载后进行编程。电子雷管的这两个关键特征为优化爆破方式和提高采矿作业效率提供了很好的机会。用于放置和装载炸药的钻孔配置以及雷管定时通常使用爆炸物理软件进行优化，这些软件依赖于从爆炸前调查中获得的有关岩石和土壤性质的一般信息以及以前在类似条件下进行的爆炸的经验。获取有关岩层中的不连续性、水位和饱和度以及以前邻近爆破操作损坏的区域的现场特定信息，将极大地提高爆破物理软件的准确性，以优化爆破规划并改善采矿活动结果。

The development of the electronic detonator has created a large level of flexibility in modern blasting applications. Detonators' timing can be minutely varied to allow exact optimization of blast patterns according to the rock and soil properties. They can also be programmed after explosive placement and loading. These two key features of electronic detonators offer a great opportunity to optimize blast patterns and increase efficiency of mining operations. The configuration of boreholes for explosive placement and loading as well as detonator timing are typically optimized using blast physics software relying on general information about rock and soil properties obtained from pre-blast surveys and experience from previous blasts in similar conditions. Obtaining site-specific information about discontinuities in rock formations, water level and saturation as well as areas damaged from previous neighboring blast operations would greatly increase the accuracy of blast physics software to optimize blast planning and improve mining activity outcomes.
