Drilling And Blasting Technology Course Swayam
This course will cover the basics of Rock geology related to drilling application, the fundamentals of drilling and blasting process during rock excavation in surface and sub Rock fragmentation size distribution is often used as an important index to account for the blasting effect because it directly affects the subsequent loading, transportation, and secondary crushing. Due to the mismatching of explosive and rock wave impedance, high boulder yield often occurs which affects the blasting effect. In this Rock Fragmentation Size Distribution Prediction and Blasting Parameter

Evaluation of blast efficiency in aggregate quarries: facts and
The stone aggregates are typically obtained by drilling, blasting, and crushing. Primarily, in-situ rocks are drilled, blasted, loaded, and hauled to the crushing plant for further processes. The results of blasting have been proved to affect every other downstream process leading to the production of various aggregate sizes (Workman and The cut blasting process can be clearly seen in Figure 3.At the moment of 240 μs, the cut area turns red, and the stress wave effect of the explosive is the largest, and it affects the whole area.At 280 μs, the stress waves of the first and third rows of charge holes are superimposed along the hole coring line, causing the rock in the hole coring Key Blasting Parameters for Deep-Hole Excavation in an Hindawi
