Blasting in mining is a chemical and physical process that occurs through the firing of explosives. It breaks mineral-bearing materials. These materials can be coal, ore and mineral stone. Blasting fragments materials, splits off rock blocks, and demolishes existing structures. The process of blasting goes through blast design prior any ...

In open-pit mine, blasting is one of the key basic operations in the mining chain. The cost of blasting accounts for 30% of the total cost of open-pit mining. The cost of blasting directly affects the safety, efficiency, and cost of subsequent operations [1 – 3]. Reasonable blasting parameters and techniques are of great significance for ...
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 …

The research results show that the impact depth of mining blasting in the Jianshan open-pit on the adjacent high and steep slope is 0–3.6 m, but the blasting has almost no damage to the deeper rock mass, thus, the blasting will not cause damage to the slope as a whole.

Blasting in open pits initiates geomechanical processes in pitwall rock mass while the mining depth grows and the mined-out space expands. Under the action of the tectonic stresses and blasting, pitwall rock mass loses its initial structure and tectonics, the closed crack open and new cracks appear, and stability of slopes in the pit changes as ...

In any blast design, the burden and the blast hole depth (or bench height) must be reasonably compatible. The rule of thumb for bench blasting is that the hole depth-to-burden ratio should be between 1.5 and 4.0. Hole depths.
