Flanders Electric Goes Head-to-Head with Electrical Engineers

Many mining companies face the problem of obtaining quality technical training for their employees. The challenge in mining today may be described as a knowledge gap, information transfer and technical training. Many companies are searching for ways to transfer technical knowledge from experienced employees to less-seasoned technicians.

Commercial-scale Test of New Technology to Recover Coal from Sludge Successful

A new technology for removing water from ultrafine coal slurry has been successfully tested at the commercial scale at an operating coal cleaning plant. The technology offers the possibility of reducing the coal slurry impoundment problem from the source. A peer-reviewed paper on this new technology was presented September 15 durring the 13th Australian Coal Preparation Society Conference in Cairns, Queensland.

Cleaning coal after it has been mined is done with water. The bulk of the coal mined is relatively coarse in size and, therefore, can be readily washed of impurities and subsequently dewatered. However, a portion of mined coal is smaller than approximately 30-40 microns and is difficult to dewater after cleaning, said Roe-Hoan Yoon, the Nicholas T. Camicia Professor of Mining and Mineral Engineering in Virginia Tech’s College of Engineering. As a result, finer coal is often discarded to slurry impoundments. There are hundreds of sludge impoundments in the United States, mostly in Appalachia, creating environmental and safety concerns, said Yoon.

Clermont Gets the Greennlight

The IPCC system is a new method of mining for Australia in general and Rio Tinto in particular. Implementing new technology, according to the company, brings many new challenges, especially during the construction and start-up phases. “The IPCC is relatively new technology in this application, and as with the rest of the Clermont Operation, we are focusing on a steady ramp up to full operational capability. For the IPCC, we expect this to be by the end of 2010,” said Andrew Cole, general manager operations, Clermont. “In 2011, there will be a major operational reconfiguration of the machine, followed by another ramp-up to full production by 2012.”

Improved Rigging System for Draglines

With significant market share in the regions that operate the most draglines, the Columbia Steel Casting Co. knows a thing or two about dragline rigging systems. The company has recently brought two new devices to the market, Mechanically Attached Anchor Brackets and the Armor Block, and the mining business has quickly embraced both. In addition to these products, Columbia Steel is also looking at new ways to improve dragline uptime for mine operators.
