The Dodd-Frank Act Implements Conflict Minerals Provisions
The mining industry was making headlines again last month. People around the world breathed a collective sigh of relief when rescue workers located miners trapped underground in a copper mine near Copiapo, Chile. Our hearts and prayers go out to those miners and their families and we wish the rescuers God speed. The Big Australian made a hostile bid for PotashCorp and the business community, for the first time it seems, connected the dots between mining for fertilizer and agriculture. Naomi Campbell testified at the Hague war crimes trial of former Liberian President Charles Taylor, casting the spotlight on blood diamonds once again. Conflict minerals also surfaced in recent legislation in the U.S......... read more

Trapped Chilean Miners Face Long Wait for Rescue
Thirty-three miners trapped in the small underground San José copper-gold mine near Copiapo in north-central Chile on August 5, 2010, were discovered to be alive and in reasonably good health in the mine’s refuge chamber on August 22 when a 15-cm drill hole from surface broke through to the chamber. A note returned to surface by the miners read, "Estamos bien in el refugio los 33." The refuge chamber is 688 m below surface. The mine is owned by a private company, Cia. Minera San Esteban Primera. Codelco, Chile’s national copper company, was moving a large rig to the mine site to drill a rescue shaft to the refuge chamber....... read more

European Commission Proposes Early End to Coal Subsidies
During July, the European Commission approved a proposal for a Council Regulation on State aid to facilitate the closure of loss-making hard coal mines in the EU by October 1, 2014. "The aim of the proposal is to ensure a definitive closure of uncompetitive mines. Companies need to be viable without subsidies. This is a question of fairness vis à vis competitors that operate without state aid. This is also in the interest of taxpayers and of government finances that are considerably constrained. The Commission will only allow operating aid to mining companies that have a closure plan and the subsidies …. read more

Rockbolting Technology Keeps Mines Safe and Secure
Operators can choose from a greater range of bolting options and equipment than ever—the challenge is to identify the best solution for local rock conditions

By Simon Walker, European Editor

In May, E&MJ took a close-up look at shotcreting technology, which is increasingly becoming a preferred means of ground support in appropriate situations. However, shotcrete is rarely used alone, especially where long-term support is needed, with rock bolts usually forming an integral part of a ground-control package. As with shotcreting, rockbolting technology has moved on over the years, with standard point-anchor bolts having been superseded by more sophisticated and long-lasting systems. That is not to say, of course, that no place remains for the simple mechanical-shell system: far from it, in fact, with its benefits of easy installation and low cost often outweighing its disadvantages……. read more

Tire Makers Get a Chance to Restock and Retrain
Safe practices and solid maintenance programs remain vital for mine operators

By Steve Fiscor, Editor-in-Chief

Not too long ago mines were desperately seeking tires for haul trucks. Commodity prices were high and mines wanted to ramp up production. Truck OEMs could deliver trucks, but could not guarantee they would have tires. The situation became so desperate, mines began to slow truck speeds to extend tire life. Those were the good old super cycle days of 2006-2007. Reality set in with the global economic crisis. With the exception of gold miners, almost all of the other miners saw prices and demand slow. The story on the aggregate side of the business was worse. Large quarries do compete with some mining operations for tires. It didn’t take long...... read more

Truck Wheels: Mine Productivity Rides on the Rim
Unscheduled wheel repairs or tire service removes a truck from the fleet as quickly as a blown engine or transmission. With an eye toward reducing the time needed for wheel- or tire-related service, both haul-truck OEMs and aftermarket wheel suppliers are offering a wider selection of wheel and rim types

By Russell A. Carter, Managing Editor

Truck wheels generally don’t attract the high level of industry interest and opinions typically aimed at engine, drivetrain or tire trends and technology, but they nevertheless represent a vital component in haulage operations. If a truck wheel—weighing anywhere from 5,500 to more than 6,500 lb in the largest sizes—breaks or runs loose on its hub, that truck goes out of service, resulting in the same production shortfall as if its engine, transmission or hydraulic system had failed, possibly complicated by expensive tire or mechanical damage …... read more

Shovel OEMs Make Major Design Improvements

AC drive technology, maintenance considerations and operator comfort take priority

By Steve Fiscor, Editor-in-Chief

Truck-shovel mining is one of the most productive methods of moving dirt. As haul truck capacities grew to accommodate the traditional 3- and 4-pass loading scenarios with the larger shovels in the pit, mine operators had to contend with a new set of parameters that included AC technology in a traditionally DC world, wider hauls roads, new loading configurations and different maintenance strategies. Maximizing shovel productivity without being overtrucked— what had been a relatively simple mining exercise—was becoming much more complex..... read more

Correcting Shaft Misalignment: Three Steps to Smooth Production

By Paul Michalicka

When shafts or belts on rotating equipment are misaligned, unplanned machine downtime probably lies ahead. In the mining industry, this can mean large conveyors and crushers coming to an unexpected and complete stop at a cost of thousands of dollars per hour in lost production. Techniques and tools exist that can spot trouble before it happens, correct the root causes, and maintain the alignment that keeps conveyors and crushers running smoothly..... read more
