A Cost–Benefit Analysis of Electric Loaders to Reduce Diesel Emissions in Underground Hard Rock Mines

PROJECT TITLE :

A Cost–Benefit Analysis of Electric Loaders to Reduce Diesel Emissions in Underground Hard Rock Mines

ABSTRACT:

With recent developments in understanding the adverse health effects of diesel particulate matter (DPM) and growing emphasis on sustainability, zero-emission electric vehicles are turning into an increasingly common option in underground mining systems. As exposure laws become stricter and with potential savings in the value of ventilation, fuel, and consumables, there is additionally rising economic incentive to think about alternatives to diesel machinery. Thus, the diesel–electrical debate is key to any underground mining company's triple bottom line. A cost–profit analysis for electric load haul dump units (eLHDs) was conducted in the context of Western Australian underground arduous rock mines. This included a review of the issues affecting the diesel–electric dialogue and the event of a parametric life-cycle-cost model. The results indicate that eLHDs are not however a universal solution to all underground mining systems. eLHDs can supply lower operating costs and do contribute many qualitative benefits, notably with respect to reduced exposure to DPM. But, they conjointly have many drawbacks, primarily related to trailing cable management. Nevertheless, with a appropriate mine design, eLHDs are a viable option and might give a pathway for zero-emission electrical machinery within the Australian mining business. Preamble —Western Australia is one of the globe's leading mineral provinces. Within the 2012–2013 financial year, Western Australia's mineral and petroleum sales totaled A$102 billion, representing some 42 $percent$ of Australia's total merchandise exports. As such, changes to the Western Australian mining trade has national and international economic implications.
