A smart look at monitoring while drilling (MWD) and optimizing using acoustic emission technique (AET).

Monitoring while drilling (MWD) is a crucial task in mining operations. Accurately measuring drill and rock-related operating parameters can significantly reduce the cost of drilling operations. This study explores the potential of monitoring drilling specific energy (SE) and optimizing drilling operations by processing vibroacoustic signals generated while drilling.

Prediction of jumbo drill penetration rate in underground mines using various machine learning approaches and traditional models.

Estimating penetration rates of Jumbo drills is crucial for optimizing underground mining drilling processes, aiming to reduce costs and time. This study investigates various regression and machine learning methods, including Multilayer Perceptron (MLP), Support Vector Regression (SVR), and Random Forests (RF), to predict the penetration rates (ROP) using multivariate inputs such as operation parameters and rock mass characteristics. The Rock Mass Drillability Index (RDi), incorporating both intact rock properties and structural parameters, was utilized to characterize the rock mass.

Environmentally sustainable mining in quarries to reduce waste production and loss of resources using the developed optimization algorithm.

The study of natural resources in the earth sciences focuses on the sustainable management of valuable materials like dimension stones. the quarrying of dimension stones is associated with environmental challenges such as significant amounts of waste production, and resource loss, mainly caused by discontinuities and fractures in the rock mass. Quarry optimization requires an optimal cutting pattern to increase the production of larger blocks while minimizing parameters that affect operational costs such as energy consumption.

Safety survey of Iran's mines and comparison to some other countries.

The increasing development of mining activities in Iran makes it necessary to have a closer look at the safety issues. Analysis of different incidents and damages in mines can be helpful for the adoption of suitable approaches to prevent the incidents. In this study, safety statistics of Iran's mines in 2011 and 2012 were assessed and important incidents and injuries happening to employees for 12 different groups of minerals were evaluated and eventually compared to the situation of some other countries.
