  • Effect of induction unloading on weakening of rock ...

    Feb 01, 2012  In fact, induction caving is a time varying process of stress transference and concentration [3 5]. It is a complicated process affected synthetically by rock excavation, dynamic unloading, fractures development and unstable collapse under gravity. The weakening of rock mechanical properties is an essential factor of induction caving technology.

    A Comprehensive Breakdown of The Mining Process and All Its intricacies.Prospecting/SurveyingExplorationMine-Site Design/PlanningDevelopmentProductionClosure/ReclamationThe mining process is responsible for much of the energy we use and products we consume. Mining has been a vital part of American economyand the stages of the mining process have had little fluctuation. However, the process of mining for ore is intricate and requires meticulous work procedures to be efficient and effective. This is why we have broken down the mining process into six comprehensive steps.See more on thebossmagazineEstimated Reading Time: 3 mins
