As with other engineering design tasks, mine design involves setting design objectives and constraints (the feasible solution space) and finding the optimal design alternative. Mine engineers often struggle to incorporate the preferences of local community members into their evaluation of mine design alternatives because the mining literature lacks tools to quantify such risks during mine planning. This paper presents an approach to evaluate community acceptance (i.e., community preferences for the alternatives) using discrete choice models and decision-based design during mine planning. Using discrete choice models and a rigorous framework, engineers can estimate the cost of social risks as a function of the probability that individuals in the host community will prefer a particular design alternative. They can then estimate the overall utility of a particular design alternative to the project proponents. This paper illustrates the proposed approach with a strategic mine planning exercise for a gold mine. The framework can be a useful tool for designing mines for sustainability, if combined with effective community engagement and management’s commitment to creating shared value.

Mining is one of the most hazardous industries as mineworkers are exposed to unsafe working conditions. One of the key steps in improving mine safety is through study and analysis of mine accident data. In recent years researchers have rigorously worked towards the analysis of mine accidents in Pakistan, but very little work if none is conducted to investigate and analyze the mine accidents reporting system in Pakistan. This research focuses towards analyzing the occurrence of surface mining accidents in Punjab from year 2004–2018 during which 377 fatalities occurred. Intensive literature review is done to understand the current body of knowledge in mine accidents in Pakistan. This work identifies that mining fatalities are increasing with each year unlike global trends with a pattern of consistent occurrence due to primitive mining practices, negligence of workers, lack of resources, slackness on part of regulatory bodies and mine management and worse accident reporting mechanism. The work finds that only fatal accidents or extremely serious accidents are reported to regulatory body. The work identifies the limitations of accident reporting tool (Form IX) as being outdated and generic that abstains from binding cause of accident to any of the stakeholder to be held accountable along with no centralized system to investigate indigenous solutions for improving safety. This work presents a new accident reporting tool that will help improving the overall safety of mining activity by binding occurrence of accidents with responsible stake holders. The approach to make stake holders accountable will result in overall ownership of mine safety in the Pakistan. The future work can investigate the proposed work and quantify the outcomes resulting from the opting the proposed system.

A thorough improvement in mine safety is contingent on many factors that require scientific decision-making for selection and prioritizing of important factors for safety improvement. Their analysis using an established scientific method can improve mines’ safety conditions and assist the administration for informed decision-making. This research establishes a mine safety evaluation index and proposes an integrative model based on the entropy weight and grey clustering methods. In the evaluation index, 27 significant factors of safety are identified and categorized into 7 criteria. The proposed evaluation system analyzes all indicators according to Pakistan’s current mine safety situation and their significance for potential safety improvement in the future. Results reveal that current safety practices are outdated due to a lack of mechanization in the mining industry and minimal capability of the management to achieve the desired safety targets. Appropriate safety policies and safety education are missing in the daily working environment. The lack of overseeing the execution of safety operations and the lack of ambition and strong work ethic workers contribute to the paucity of mines’ safety conditions. The prevention and control systems to manage risks and hazard are not in place, and the working environment in mines remain difficult. Therefore, to have enhanced mine safety, important factors can be addressed in chronological order, as presented in this paper. The proposed methodological approach can be applied to other prioritization applications to analyze the indicators and determine the appropriate management strategies.

This work evaluated the effect of bucket orientation and operating parameters on resistive forces and penetration for rubber tire loaders. The work used a 1:16 scale LHD model to test a rubber tire loader (RTL) bucket operating at different levels of tractive effort, speed, digging height, and rake angles in a full factorial design experiment. The work repeated the test on two different muck piles with different particle sizes and used generalized regression modeling to test the association of rake angle, tractive effort, speed, and digging height on penetration and resistive forces for RTL buckets. The results show that speed and tractive effort are more important in explaining RTL penetration and resistive forces than height above the floor and rake angle. Speed, tractive effort, and height above the floor are positively correlated to bucket penetration, whereas the rake angle is negatively correlated to penetration. Similarly, speed, tractive effort, rake angle, and height above the floor are all positively correlated to resistive forces incurred during initial penetration. The observation that the combined effect of speed and tractive effort is negatively correlated to penetration and resistive forces is a novel contribution that enhances our understanding of RTL loading. The results also show that the effect of speed, tractive effort, and height above the floor all change with changes in particle sizes. This work adds to the literature on the effect of rake angle, height above the floor, tractive effort, and speed on penetration and resistive forces for rubber tire loaders.

Autonomous mining systems comprise of the latest, innovative, and automated technology designed to improve mine productivity, efficiency, and workplace safety. These automated systems have already been adopted in developed countries like Australia and the United States. In recent years research has emerged to address the awareness and preparedness of stakeholders towards the adaption of Autonomous Mining Systems dedicated towards African countries. The present study is a novel effort in evaluating the current scale of knowledge and skills of mining engineers working in Pakistan's mining industry, government sector, and academia. The study focuses on exploring the awareness about the understanding of the autonomous mining systems, and the level of preparedness of all the stakeholders towards the adoption of this modern technology, along with the resulting social impacts, in a developing country like Pakistan. This paper employed closed and open-ended questionnaires, distributed in electronic formats, to achieve the aforementioned objective. The results were analyzed qualitatively using thematic analysis and quantitatively using results synthesis employing statistical analysis in Python. Substantial evidence has been provided indicating a huge knowledge gap and severe lack of planning and policy enforcement towards the adoption of autonomous mining systems in Pakistan. More than 74% of the respondents, with the majority of them belonging to industry and academia, appeared willing to accept the adoption of autonomous mining systems in Pakistan, due to the resulting improvements in safety and productivity. However, government agencies had varied opinions, with the knowledge gap and the fear of increased unemployment being the major reasons for their resistance to technology adoption. The majority of the graduate mining engineers (60.35%) mentioned the inadequacy of the undergraduate and graduate coursework for providing skills needed to work with autonomous systems. Therefore, it is recommended that the mining curriculum be revised to contain more courses that are relevant to gaining skills in autonomous mining. A government-industry-academia collaboration is also recommended to fund and develop facilities that can help bridge this existing knowledge gap, thus facilitating an early adoption of modern technology in Pakistan's mining sector.

This work evaluates the effect of increasing level of detail in emergency alerts on underground miners’ emergency evacuation decisions. An offline survey was administered to underground miners, which provided miners simulated alerts with ever-increasing levels of information about fire, cave in, and explosion emergency scenarios. The simulated evacuation exercise evaluated differences in evacuation decisions due to the channel of communication (text message or through a co-worker). The results indicate that the content of the alert messages has a significant effect on miners’ decisions with more miners choosing to evacuate when more detail is provided about the urgency of the situation. The results also indicate that the evacuation decisions of the participants are related to their mining experience, marital status, age, income, and use of technology. Depending on the scenario, 51–70% of the miners chose not to shelter in place or go to the refuge chamber as instructed in the simulation. This tendency to ignore guidance is possibly due to a lack of clarity in the message sent to them or the poorly crafted messages that do not account for how the miners will account for risk under uncertainty. It appears that the miners are acting in a loss-averse manner given the uncertainty, as per prospect theory. This study also concludes that, overall, the channel of communication does not significantly affect the miners’ evacuation decisions. This may bode well for using text message alerts in mine emergency management. This work presents a foundation for developing effective text messages for guiding miners in emergencies by building off existing research on short-form emergency warnings and applying the principles to the mining context to provide evidence for new emergency alert technologies mandated new underground coal mine safety regulations. Future research should evaluate miners’ decision-making using prospect theory to account for miners’ perception of risk under uncertainty, so that persuasive text messages can be designed to elicit safe evacuation decisions.
