Systematic Ground Support - The Ontario Example

By: MacLean Engineering

Downloads: 15Views: 268

The cause for the large drop in fall-of-ground fatalities in Ontario, Canada since the 1960s can be attributed to a variety of factors including increased regulation, better engineering and ground support practices, and the buildup of a stronger culture of safety in mines.

What's in a number? The economics of battery power in underground mining

By: MacLean Engineering

Downloads: 4Views: 660

The drivers pushing mining companies to seriously look at the EV transition encompass a broad range of benefits – reduced ventilation requirements (30-50% less) and associated energy costs, elimination of diesel fuel costs (tens of thousands of dollars per EV unit, per year), reduced maintenance costs (some 25% fewer parts on EV propulsion vs. diesel propulsion rigs), elimination of diesel fine particular matter in the underground environment, and last but definitely not least - less noise, vi ...

Jackleg safety and mechanization

By: MacLean Engineering

Downloads: 28Views: 1218

483 MSHA reportable injuries involving jacklegs occurred at US mines between 2003 and 2012, according to a recent study published by NIOSH (Clark et al., 2016). And these are just the reportable injuries - if you consider the “Heinrich Safety Triangle”, this can be viewed as the tip of the iceberg. What are the options for mechanization?

Battery power for underground mining equipment - the non-battle of chemistries

By: MacLean Engineering

Downloads: 86Views: 1898

The successful introduction of battery power to hard rock mining isn’t going to be about the correct choice of battery chemistry alone, it will be about engineering a battery propulsion system that is fit-for-purpose with the mining application and duty cycle, and one with maximum flexibility to allow for the rapid pace of battery technology advances that will inevitably open up options for diesel-free mine planning and retrofitting. http://www.macleanengineering.com/media-en/blog

Reducing Whole Body Vibrations for miners

By: MacLean Engineering

Downloads: 14Views: 1010

Making front suspension the standard, not the option: An increasing body of research is linking chronic Whole Body Vibration exposure to musculosketal disorders such as lower back pain, and these disorders are now the leading cause of chronic injury and absenteeism in the Canadian and US workforces. So for a mining industry facing prolonged pricing headwinds, keeping workers healthy and productive isn’t just the right thing to do, it’s also essential to surviving the downcycle to prosper ...

Secondary Breaking: MacLean Ore Flow Product Line

By: MacLean Engineering

Downloads: 25Views: 1242

Oversized hang-ups present significant challenges to ore flow for mine operators. MacLean’s comprehensive suite of ore flow solutions starts with Water Cannons as a first line of attack to bring down hang-ups; it progresses to low, medium, and highreach Blockholer drills for persistent hang-ups and secondary breaking; then moves to the Mobile Rockbreaker for fragmenting the oversize at source without blasting. www.macleanengineering.com

Secondary Breaking: Top 5 reasons to love your self-contained Blockholer

Downloads: 19Views: 1186

Whether it’s a low hang-up in a drawpoint, or oversize rock on the ground that’s too large for scoops to handle and too disruptive to get rid of with concussion blasting, it’s your secondary reduction rig that solves the problem and ensures that production isn’t held up. And when it’s not tasked with this mission, it can be put to use for ancillary drilling for mine services. www.macleanengineering.com
