Modern mines have rigorous safety procedures. Mines in Canada, in particular, are veritable havens when it comes to safe work conditions compared to those in China, Africa and South America—places notorious for their blatant disregard for miner safety. Despite the high standards, though, Canada’s mining industry still faces some safety issues that must be addressed on a constant basis. Mining Health, Safety, and Prevention Review Ontario recently concluded a year-long mining health and safety review led by the province’s Chief Prevention Officer, George Gritziotis. The review’s results, which involved input from an advisory group comprised of mining, labour, health, and safety representatives, were released in Sudbury on April 15, 2015, and detailed several recommendations on how to make the underground mining sector safer overall.

Mining is a multibillion dollar industry obviously because of its colossal role in industrialization. It can be done in two ways—creating an open pit or an underground operation. Open-pit mining is ideal when ground inspection suggests that there’s a huge volume of ore deposit under the mining site. Underground mining can be done if the ore deposit is concentrated in deeper areas. The latter is a more popular option, especially if the mine site is surrounded by structures or close to a community. In underground mining, shafts are developed to provide workers and machines with access to the ore underneath. Once a shaft is built, mine skips and cages will be installed for the transportation of extracted ore, equipment and employees. The ore will be drilled and crushed to be easily conveyed through the skips. After extracting all ore deposits, the shaft will be closed by filling with the overburden produced during excavation.

Besides the inward pressure exerted by the soil, the shaft is also subjected to friction, tension, and compression created by the moving and stationary load within it. The mine cages and skips must be made of the toughest alloys of steel to withstand tension. This is to protect the passengers and reduce the stress passed on to them through each conveyance cycle. Mine companies have to entrust the manufacture of shaft conveyances to reliable mine equipment manufacturers like Wabi Iron & Steel Corp. These companies follow the highest industry standards to ensure that their equipment perform well and last long, and employ highly skilled tradespeople. Engaging equipment manufacturers such as these will ensure the continuity and success of the mining operation.

Longwall and Room & Pillar mining are two popular underground mining methods. In Room & Pillar mining, a network of “rooms” are cut into seams. Pillars are left in place to support the roof in a regular pattern while the rooms are mined out. On the other hand, Longwall mining involves the use of mechanized shears to cut and extract ore at the face of the mine. Extracted ore is then dropped onto a chain conveyor system that will ultimately take the ore to the surface. Temporary hydraulic-powered roof supports are used instead of pillars to hold the roof up. Investing in the development of new mines can be attractive for companies when metal prices ensure profitable operations. When planning for the transportation of ore within a new mine, it is important to partner with a trusted manufacturer of underground rail cars and other conveyance equipment such as Wabi Iron & Steel Corp.

With the Ontario mining industry’s growing demand for improved safety, manufacturers of wear resistant castings for underground equipment requirements must ensure that their products are built to the highest of quality standards. The parts produced by these manufacturers play an important role in providing miners with dependable and high-performance equipment that will keep them safe. Mining equipment manufacturers and Ontario foundry specialists like Wabi Iron & Steel Corp. have product engineers who are experts in designing safe and reliable products. Some of these companies also have advanced on-site laboratories that help them create customized solutions for specific customer requirements. These firms can address most any abrasion, impact, and heat-resistant casting need for the manufacture of impactor parts, crusher parts, pump parts, chute liners, track pads, mine car wheels, and many other products.
