EXPERIENCED ELECTRICIAN DIES IN COAL MINE ACCIDENT
Serious or fatal injuries don’t just happen to inexperienced workers, or those in unfamiliar work settings. An electrician with 21 years of experience was troubleshooting a dragline trailing cable at a surface coal mine when he contacted two energized phase conductors.
He was working at an electrical junction box that supplied power to the dragline when the incident occurred. The electrician sustained fatal injuries.Most mining draglines are not fuel powered: their power consumption is so great, they have a direct connection to the high-voltage grid. Although the electrician had disconnected and locked out incoming power to the junction box, when an onboard diesel-powered generator was started, it back-fed 480V through on-board transformers connected to the dragline’s trailing cable, energizing the phase conductors to 23,000 volts.
The U.S. Dept. of Labour’s Mine Safety & Health Administration (MSHA) has released a list of best practices for preventing such tragic incidents:
• Before performing electrical work on draglines, shovels, etc., lock out and tag auxiliary power sources with YOUR lock. These types of machines often have auxiliary power sources located on-board or positioned nearby.
• Install a failsafe mechanical interlock system that will prevent the auxiliary power and normal power sources from being connected to the same circuit at the same time.
• Always connect each phase conductor to the system ground prior to performing high-voltage electrical work.
• Never enter electrical vaults, motor control centres or other electrical enclosures unless you are qualified to do so, or under the direct supervision of someone who is.
• Always wear proper safety equipment when performing electrical work.
• Never assume you understand a circuit. Thoroughly research how it is wired.

CONTRACTORS GATHER IN OTTAWA FOR NATIONAL CONFERENCE
If you haven’t already, mark your calendar for the 2007 National Industry Conference presented by the Canadian Electrical Contractors Association (CECA), and hosted by the Electrical Contractors Association of Ontario (ECAO).
CHANGE IS GOOD is the theme of this year’s event, being held June 13-16, which will feature exciting speakers and great social functions held in some of Ottawa’s finest venues, including the Westin Ottawa. Located in the heart of the city, this hotel is the ideal location with its indoor walkways to both the Rideau Centre Shopping Mall and Ottawa Congress Centre, not to mention its proximity to the many historical and cultural elements of the city.
The conference kicks off with the Welcoming Reception held at the National Gallery, where delegates will have a chance to get reacquainted. An added bonus during the reception will be a private viewing of the Renoir Landscapes—60 of Renoir’s most beautiful landscape paintings on loan from leading art museums and private collections around the world. (Ottawa is the only Canadian venue for this travelling exhibition, providing a unique opportunity for conference delegates!)
The weekly presentations begin with keynote speaker, Warren Macdonald, the first double above-knee amputee to reach the summit of Africa’s tallest peak, Mount Kilimanjaro, and America’s tallest cliff face, El Capitan. Meantime, luncheon speaker and political guru, Mike Duffy, will paint a picture of Canada’s political scene... its colourful history and ever-changing landscape.
Educational opportunities abound throughout the week on marketing, productivity, management, finance, health and safety, and more.

GIVING ENERGY WASTE THE SLPP
By Bryan Young
Do you have a leaky hot water tap in your home? A drop here, a drop there... it’s no big deal, right?
Wrong! A leaky tap, at one drop per second, wastes 800 litres of water per month, not to mention the extra money you’re spending to heat it. It all adds up to the drip, drip, drip of your energy dollars going right down the drain. Fixing it is just as easy as replacing a rubber washer that costs a few pennies.
In much the same way, the Ontario Mining Association (OMA) and Ontario Power Authority (OPA) have teamed up to fix another kind of small, steady leak that wastes energy and costs mines thousands of dollars a year. In this case, it isn’t water but compressed air that is the energy-guzzling culprit.
The Sustainable Leak Prevention Program (SLPP) now underway at three northern Ontario mines should not only improve electricity efficiency, it could help all mining companies save hundreds of thousands of dollars in their operations, not to mention benefit other industries that use compressed air in their operations.
Ontario’s mining industry spends more than $500 million each year for energy, and this ranges from 15% to 30% of operating costs depending on the type of operation. Compressed air systems, found in underground mines, are one of the largest contributors to electricity costs. Even small air leaks in these systems can increase costs substantially by causing compressors to work harder.
For example, one tiny hole (about 1/8-in. diameter) wastes air at a rate of about 12 litres per second. Even at the low rate of $0.04/KWh, this alone can waste more than $1000 per year; and industry knows that most systems using compressed air have many leaks. Some plants experience a leak rate equal to 20% of total compressed air production capacity.
In a $532,000 project, the Ontario Mining Association will oversee audits of compressed air systems at the Williams Mine in Hemlo near Marathon, CVRD Inco’s South Mine in Sudbury and FNX’s McCreedy West Mine (also in Sudbury).
At the Williams mine—one of the largest gold-producing mines in Canada—employee/public relations co-ordinator Roger Souckey says, “Compressed air systems represent one of our greatest areas of operating and energy inefficiency.” He adds, “The longer a leak goes undetected, the more compressed air and electricity we waste, and the less efficiently our equipment operates. A key deliverable of the program will be establishing a trigger mechanism that will prevent leaks by telling us that preventive maintenance is required.”
“Repairing compressed air leaks in the mine is a cost-effective way to increase energy efficiencies and to ensure ongoing low-cost nickel production,” says Dave Tomini, divisional energy co-ordinator at CVRD Inco. “This initiative is in line with our continuing efforts to build a sustainable future.”
Dave Secord, senior maintenance co-ordinator at FNX McCreedy West mine says, “With training, and the management of this program, we are hoping to detect the problems right away and turn this into a cost saving in electricity as well as maintenance on our compressors.”
Key findings of the audits will be presented to the OMA in March, with a final report submitted to OPA in May.
Funding for 41% of the project comes from OPA’s Conservation Fund, with the balance provided by OMA and participating sites. The Conservation Fund was established to mobilize as many sectors of the Ontario economy as possible to embrace a culture of conservation. It focuses on enabling conservation education and electricity reduction through pilot projects. Key learning points from each of the programs are then shared across all sectors help spark similar programs and/or build pilot programs into full-scale initiatives.
The fund needs help designing future programs! Partnering with groups like OMA helps better promote energy efficiency and a culture of conservation in Ontario. After little more than a year, the Ontario Power Authority’s Conservation Fund has provided $2.5 million to 37 electricity conservation projects in a variety of sectors of the Ontario economy.
