Unplanned Dilution Prediction In Open Stope Mining: Developing New Design Charts Using Artificial Neural Network Classifier, Sultan Korigov, Amoussou Coffi Adoko, Fhatuwani Sengani
Journal of Sustainable Mining
Minimizing dilution is essential in open stope mine design as excessive unplanned dilution can compromise the operation's profitability. One of the main challenges associated with the empirical dilution graph method used to design open stopes is how to determine the boundary of the dilution zones objectively. Hence, this paper explores the implementation of machine learning classifiers to bridge this gap in the conventional dilution graph method. Stope performance data consisting of the stope dilution (unplanned dilution), the modified stability number, and the hydraulic radius were compiled from a mine located in Kazakhstan. First, the conventional dilution graph methods were used …

Novel Approach For The Destress Blasting In Hard Rock Underground Copper Mines, Piotr Mertuszka, Marcin Szumny, Krzysztof Fuławka, Piotr Kondoł
Journal of Sustainable Mining
The present study investigates the possibility of developing a novel method for reducing seismicity and rockbursts in deep underground mines based on modifying drilling and blasting patterns. The main goal was to develop and implement firing patterns for multi-face production blasting, which allow increasing the capability of inducing stress relief in the rock mass, manifested in the seismic event. This method may improve stability control in underground workings, and mitigate risks associated with the dynamic effects of rock mass pressure compared with currently used methods. Thus, the seismic energy may be released immediately after blasting in a controlled way. For …

Improved Methodology For Monitoring The Impact Of Mining Activities On Socio-Economic Conditions Of Local Communities, Binay Prakash Pandey, Devi Prasad Mishra
Journal of Sustainable Mining
Mining activities can cause tangible socio-economic improvements in the surrounding regions. Such potential has not been fully realized, owing to the fact that the socio-economic impact assessment processes exercised in India merely predict the footprint of industrial activity on the surrounding population. Consequently, project proponents are mandated to implement a management plan in cases of foreseeable negative consequences. However, both, the assessment study, as well as the process of implementation of a management plan, are riddled with significant gaps and limitations. Primary data collected for this research makes it apparent that, in comparison to the revenue generated from the mining …
