Education, Empowerment and Exposure

During May, Engineering & Mining Journal (E&MJ) hosted the Haulage & Loading conference in Phoenix, Arizona. More than 300 people attended the three-day event, where experts talked about all aspects of operations and management. The technical program kicked off with a session on safety training. Two experts talked about successful strategies that they had implemented. Most of the discussion boiled down to better educational procedures, treating people like people, and eliminating the potential for accidents to occur. Implementing these programs requires leadership, which differs from management skills, and a big commitment as far as effort.

Today most of the safety dialogue revolves around the constant pursuit of zero— zero fatalities, zero lost time accidents, etc. While that is an ambitious goal, safety experts doubt that any company can achieve it until ......... read more

Labor Issues Continue to Roil South Africa’s Mining Industry
Impending wage negotiations between labor unions representing workers at South Africa’s gold and coal mines and the Chamber of Mines of South Africa, representing the mining companies, were scheduled to begin in early June 2013. In late May, the National Union of Mineworkers (NUM) said in a submission to the Chamber of Mines that it would be seeking an entry-level minimum monthly wage of R7,000 for gold and coal surface workers, up 49% from about R4,700,  60% from about R5,000. (The South Africa rand/U.S. dollar conversion rate at the end of May was about R10 = $1, near a 10-year low for the rand). NUM also said it wanted......... read more

Underground Rock Handling
Recent developments in both traditional and unconventional systems for moving rock in underground mines

By Simon Walker, European Editor

In many respects, the choice of haulage system for an underground mine is dictated by the orebody geometry. Narrowvein systems or orebodies that are elongated vertically lend themselves to an LHD-based system centered around a series of orepasses. For ore zones that are more tabular, or are geographically spread out, using LHDs to load mine trucks that then transport material either to an orepass or directly to surface via a ramp may be a better option. High-capacity, bulk-tonnage mines, by contrast, may find that a fixed infrastructure network using either high-tonnage trucks or rail-bound haulage is the most economical way of moving their ore. And, while conventional belt conveyors are less-commonly used in hard rock mining than in coal, for instance, there are always innovations being developed and trialed that offer an alternative means of rock transport……. read more

Dynamic Earth Model Offers New Exploration Insights
Miners looking deeper underground for new mineral deposits need better tools to reduce risk and identify favorable locations. Comprehensive digital subsurface models offer improved technology to accomplish both of those goals

By Simon Walker, European Editor


According to Dr. Graeme Nicoll, head of the minerals exploration group at the U.K.-based earth-science research company, Neftex, as the number and quality of new mineral deposit discoveries continue to decline, miners are being forced deeper into the subsurface realm to access mineral wealth. This, he said, then exposes the sector to greater risk and financial uncertainty. While the tools and technology for accessing and exploiting subsurface deposits are advancing, Dr. Nicoll explained, identifying the right location to explore is increasingly becoming more of a challenge. New tools are therefore required that will identify subsurface or “blind” deposits, and offer a predictive model to increase discovery and exploration efficiency ..... read more

Leveraging Lubrication
It’s a time-worn adage, but still true: pay now or pay later. When it comes to proper lubrication of mine equipment, a few dollars spent now can help avoid major unplanned costs in the future.

Mine operators—pressured on one side by rising material and labor costs, and on the other by softening commodities markets— are naturally interested in getting the last ton of productivity out of their primary fleet equipment, at the lowest operating cost. Under these circumstances, it’s tempting to consider measures that could lead to lower expenses for two of the major consumables involved in loading and haulage: fuel and lubrication products such as engine oil. But when it comes to lubrication, cutting corners—extending oil change intervals, using cheaper filters, or simply ignoring oil condition, for example—can result in false economies. As the following case histories illustrate, real savings are often generated by investing attention and relatively small amounts of money to maintain proper lube standards and service, avoiding the much larger costs of premature engine overhauls, unscheduled downtime and failure to reach projected equipment service-life goals, among others…... read more

A Promising New Development in Coal Analysis
By Richard Woodward

Productivity growth in the U.S. coal industry from 1985 to 2000 was remarkable, from about 5,200 tons/ miner per year in 1985 to almost 15,000 tons/miner per year in 2000, a compound annual growth rate of almost 8% per year (See Figure 1). Admittedly, some of those efficiency gains can be attributed to the Powder River Basin’s increasing share of production and its scale advantage. Yet, productivity growth of 8% is hard to ignore. What’s equally remarkable is that this growth occurred without any significant breakthroughs in mining technology. Everything that characterized stateof- the-art mining equipment in 2000— from longwalls to heavy media cyclones to high-speed rail loadouts—already existed in 1985, although belt speeds and haul truck capacities continued to increase..... read more
