  Enhancing rock fragmentation assessment in mine blasting

  2024425 · The optimization of blasting operations greatly benefits from the prediction of rock fragmentation. The main factors that affect fragmentation are rock mass characteristics, blast geometry, and explosive properties. This paper is a step towards the implementation of machine learning and deep learning algorithms for predicting the extent …

  Initiating Safe and Successful Blast Practices | Agg-Net

  201448 · Blasthole management post-drilling, including collar consolidation (collars that are stable and do not collapse), depth measurement, water content and backfill. No blast will be successful if blastholes are not drilled in the correct location at the designed angle and to the right depth. Blastholes are often over-drilled to counter fall-back.

  Theory and numerical simulation of deep hole cut blasting …

  202391 · The proportion of the upper charge has an obvious influence on the cutting effect. Based on the evaluation of the number of particles thrown, the uniformity of damage, the displacement of the bottom particles and the cutting efficiency, it is found that the blasting effect is the best when ε = 0.5 among all the three considered values of ε.
