A new index of rock-breaking tool efficiency

Journal of Mining Science, 2016
Based on the analysis of qualitative interaction between rocks and a rock-breaking tool, a new coefficient of the tool efficiency is proposed. This coefficient makes it possible to estimate the quality of the tool impact on broken rocks and to predict energy input of rock breaking and, consequently, productivity of mining machines in specific ...

Three-dimensional simulation of rock breaking efficiency under various impact drilling loads

Arabian Journal of Geosciences, 2020
Percussion drilling is believed to be an efficient way to enhance the drilling performance, compared with the conventional drilling in deep wells, which could be achieved by applying impact loads above the drill bit. The finite simulation is an efficient method to predict the drilling performance when the drill bit interacts with rocks. In contrast, as

Rock Breaking Using Supercritical Carbon Dioxide (SC-CO2) Technology – A Safe, Efficient, and Sustainable Approach

AIJR Proceedings, 2022
Rock breaking by drill and blast using chemical explosives has been a dominant method in construction. However, blasting is hazardous and risky in nature: it involves the use of Category 1 Dangerous Goods; and it induces ground vibration and risks of fly rocks and air over pressure.
