![]() However, the introduction of technological innovation does not guarantee that this challenge will be met with success. ![]() The choice of equipment must therefore meet the two-fold challenge of increasing productivity while improving OHS. The importance of occupational health and safety (OHS) is increasing for many mining companies, who now face mounting social pressures. However, unlike during the early days of this industry, productivity can no longer be the only factor taken into consideration when choosing new equipment. These exogenous factors push mining companies to examine technologies as means of improving productivity. Compounding this pressure is competition from developing nations. The mining industry evolves in an economic environment that undergoes continual change due to cycles of fluctuating metal prices at the whims of international trading of securities. Mining, Innovation, Equipment, Productivity, Occupational Health and Safety Taking into consideration these key factors and their critical threshold values will help the directors of the participating mine to meet with success in terms of both productivity and OHS in future introduction of innovative equipment projects. Seat quality was identified as a contributor to improving accident rate, while standardisation of the new equipment relative to the old contributed to productivity. Two factors were found most relevant to all four indicators of performance: the skill requirement and acceptance of the equipment by the operators. The tool allowed simultaneous identification of the most relevant factors and critical thresholds thereof to establish levels of performance based on four indicators, namely cost per meter drilled, cost per hour of use, availability ratio and accident rate. Ten innovative equipment projects carried out in an underground mine in Quebec were analysed. We used a multi-attribute decision-aid tool, namely the dominance-based rough-set approach. The aim of this study is to identify the key factors that underlie successful introduction of new equipment in underground mines. However, innovative equipment does not by itself ensure success. Introduction of innovative mining equipment must now meet the double challenge of improving both productivity and OHS. This change in mentality has had an impact on the choice of new equipment introduced underground. With increasing social pressures over the past two decades, mining companies have become more concerned with occupational health and safety (OHS). ![]() Received 9 March 2015 accepted 5 April 2015 published 8 April 2015 This work is licensed under the Creative Commons Attribution International License (CC BY). Wrestleview also reported that Bautista confirmed things had been escalating for a while between Booker T and himself, and the fight had been a long time coming.1Department of Mechanical Engineering, École de Technologie Supérieure, Montréal, CanadaĢDepartment of Management, Université du Québec en Abitibi-Témiscamingue, Rouyn-Noranda, CanadaĮmail: © 2015 by authors and Scientific Research Publishing Inc. Said colleagues were also reported to be quite happy with the way Booker T stood up to Bautista, and other wrestlers were shown hugging and high-fiving Booker after the incident. Locker room whispers indicated that bad blood had been brewing for quite some time because of Bautista's bad backstage attitude - the big man had allegedly started to make comments that he "carried the company on his back" and that he was drawing in the most money, and his relatively quick rise to the top of the food chain and lack of humility had angered many of his colleagues. Wrestleview reports the fight took place when the men shot an ad for the upcoming Summerslam event, and while it was initially thought to be a staged incident to drum up hype, reports soon emerged that it had been a legitimate physical fight. In 2006, he even allegedly got into a real fight with fellow wrestler Booker T (above). While Dave Bautista was a huge WWE superstar, rumors claim he had (and caused) his share of backstage trouble.
