(PDF) ROCK BLASTING FOR MINING ResearchGate

Bender (1999) defined production blasting as the type of blasting that is designed to fragment a predetermined volume of rock; In this research, the system dynamic method for modelling drilling and blasting operations was proposed. This model could efficiently connect and evaluate all Optimized design of drilling and blasting operations in open pit

Iron ore extraction techniques ScienceDirect

The deep mining of iron ore is unusual in the modern era, but in northern Sweden, ore is mined from considerable depth largely aided by the application of Therefore, authors of this article propose a new way of optimization of the drilling-and-blasting process by introducing new blast design modifications. Based on the analysis, Optimization of the drilling-and-blasting process to improve
