Heavy Equipment Needs Stainless Steel Castings to Combat Heat and Corrosion

Industries such as mining, forestry and construction require the use of heavy-duty machines that are often subject to intense working conditions resulting in extreme wear and tear. In many cases, equipment wear parts made with steel castings are responsible for extending machine operating life and reducing downtime. These types of castings, for example, provide mining wear parts for a wide range of equipment including crushers, chute liners, mine car wheels and pumps. When resistance to heat or corrosion is needed, wear parts produced with stainless steel provide the solution. An Overview of Stainless Steels To be classified as corrosion resistant, stainless steel will contain a minimum of 10.5% chromium to provide additional resistance in aqueous environments where corrosion is a factor. The chromium content enables the formation of a protective film that increases corrosion resistance and, at higher temperatures, improves resistance to oxidation and enhances rupture streng

Australian Mine Illustrates the Importance of Mine Skips and Shaft Hoisting

Located in Queensland, Australia, Ernest Henry Mining is a Glencore company that first began operating in 1998 as an open pit mine. As the open pit’s economic life span was due to end in 2011, plans in 2009 were confirmed to invest $589 million and transform the mine to underground shaft mining. By early 2012, a 5 km decline had been established to enable the trucking of ore from underground to the surface. Rates of production with this method were approximately three million tonnes annually resulting in about 25,000 tonnes of copper concentrate and 35,000 ounces of gold concentrate per year. By moving to shaft hoisting, 2015 production was forecast to double to six million tonnes of ore. That rate is projected to be achieved on an annual basis over the extended lifespan of the mine to 2026.

The Role of Mine Cages in a Successful Mining Operation

Underground mining requires a number of different transportation systems. To effectively move miners and their equipment, for example, a dependable mine shaft cage is necessary. A mine’s success relies on the efficient operation of this component. If a serious problem occurs with the cage, conveyance activities must be suspended to ensure the safety of the miners and, when that happens, production is impeded. Improved Productivity A well built and properly maintained mine cage can also help to improve worker productivity. Workers feel more comfortable in their underground environment knowing that they have a readily available and trustworthy means of transport to take them back to the surface when necessary. As well, a dependable mine cage can effectively transport the equipment required to keep a mine operating at optimal production levels.

Factors Affecting the Efficient Operation of Mining Cars in Underground Operations

Mining operations greatly rely on machinery and conveyances. The right equipment has to be in place so that extracting and transporting of ore can be accomplished as efficiently as possible. Mining cars are one type of underground conveyance equipment that greatly influences the activities at a mine site. They make it possible to move ore towards hoisting areas for transport to the surface. Mine cars also serve as a transport for tools, equipment, and even workers. Compromising the transport system in a mine will affect the productivity and success of numerous mining activities. Sufficient budgets for regular maintenance and updating of mine cars, for example, have to be allocated to ensure that they remain in good operating condition each and every day. There are a number of considerations to be made when a mine is implementing a conveyance system.
