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.

电子雷管的发展为现代爆破应用创造了很大的灵活性。雷管的时间可以根据岩石和土壤的性质进行微调，以精确优化爆炸模式。它们也可以在炸药放置和装填后进行编程。电子雷管的这两个关键特性为优化爆炸模式和提高采矿作业效率提供了很大的机会。利用爆炸物理软件，根据爆破前调查获得的岩石和土壤性质的一般信息以及以往在类似条件下的爆炸经验，对炸药放置和装填的钻孔配置以及雷管定时进行优化。获取特定地点的岩层不连续面、水位和饱和度以及之前邻近爆破作业造成的破坏区域等信息，将大大提高爆破物理软件的准确性，从而优化爆破规划，改善采矿活动成果。
