The C-Shaft headframe in Yellowknife, originally constructed in 1948, has been one of the most iconic images in the region. The headframe has been there for the entire lives of many local residents. It is a landmark that is displayed on t-shirts, stamps and in history books. However, the headframe is currently being dismantled as part of the Giant Mine remediation project that started in 2013. People have mixed feelings about the structure’s demise. Some feel it is like erasing part of their history while others believe that it’s time to move on. Read more
Due to excessive heat and friction involved in mining, corrosion and wear is one of the most prevalent problems in the industry. Millions of dollars are lost due to halted production, worker injuries and unscheduled repairs as a result of wear and corrosion on equipment. Although replacement and repairs are an inevitable part of maintaining mining equipment, there are ways to minimize losses due to continuous usage under harsh conditions. There are a number of methods that can slow down the effects of wear and corrosion, particularly for crucial parts such as heat-resistant steel castings.
Mining is a millennia-old industry that has experienced many advancements. Throughout the years, new equipment has been designed to make mining more efficient and safer for workers. Perhaps one of the most challenging aspects of the industry lies in maintenance of loading, dumping and haulage equipment. Due to the harsh nature of the work and the environment, equipment such as aluminum mine skips, cages and loading stations experience considerable wear and tear. If one essential piece of equipment is compromised, the entire mining process could be crippled.
Mining companies specializing in underground mining know that each mine is unique as each deposit has its own set of geologic, geochemical, and geophysical characteristics. The same holds true for mine shafts and mining cages and, though they are built in accordance to applicable standards and regulations, they are ultimately designed to meet the needs of the operation and the site.
While numerous mining companies conduct surface mining at their sites, as ore deposits run deeper the associated costs can become prohibitively expensive. One particular indicator is the strip ratio, or the number of waste materials in units that a mine site must remove in extracting one unit of ore. Mining operations that are subject to a larger strip ratio can turn to underground mining as a more cost-efficient and land-friendly investment.
In Canada, Ontario is among the frontrunners in the mining industry. According to the Ontario Mining Association, the province has 40 mine sites currently operating. The area is renowned as the largest producer of salt, copper, platinum group metals, nickel, and gold in Canada.
In every underground mining facility, each component of the shaft must be able to carry out its respective functions efficiently for the whole operation to succeed. Among the components of note are the skips. As Britannica explains, mine skips act as shaft conveyors for transporting gathered ore from underground to the surface. This equipment is also used for transferring waste rock and debris for disposal.
Mines are dangerous environments—that’s why safety is a huge concern in the mining industry. When mining accidents result in injuries or fatalities, the issue of safe work conditions becomes extremely significant. So how does a mining company enhance safety throughout all of its functions? The International Powered Access Federation (IPAF) aims to supply some answers.
Mining Cars and Beyond: Extending the Mineral Exploration Tax Credit is Good for Canada’s Mining Industry
When Prime Minister Stephen Harper made a stop in the battleground riding of Nipissing-Timiskaming in Northern Ontario, he mentioned to a group of supporters in North Bay the Conservative Party’s plan to extend the 15 percent Mineral Exploration Tax Credit for, at least, another three years if the government is re-elected. Meanwhile, projects in remote locations will qualify for a 25 percent tax credit.
Metal casting involves the creation of alloys through the melting and molding of different types of metal. This process plays a vital role in the production of high-quality metals used in mining equipment manufacturing, construction, and various other industries. Read more
