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. Steel is among the most extensively cast metals. It is an alloy of iron and other elements, primarily carbon. Different mixtures produce different types and properties of steel; with the right mixture, extremely tough and corrosion-resistant materials can be produced. Steel is one of the very few metals that serve a wide variety of uses because of its versatility when combined with other materials.

Mining is one of Canada’s richest sources of income and employment. Over 380,000 people benefit from this industry. Mining has long fueled the economy by providing the building blocks of industrialization, which in turn has created more businesses and job opportunities. Dangers in the Mine Miners face various kinds of risk every time they venture deep into the earth. Accidents due to human, mechanical or natural causes sometime happen. An underground rock fall, for instance, can delay operations and entail lengthy and costly repairs. Equipment malfunction or inefficiency can also have negative effects on production. These situations not only put miner safety at risk but they also curtail a mine’s overall productivity which, in turn, impacts profitability.

Mining is an industry that pushes the envelope in engineering, and things get even more extreme when it comes to underground mining. The use of underground mines is necessary for excavating at depths greater than 60 metres (the point where surface mining turns inefficient). How Stuff Works highlighted the wide range of depths that underground mines can reach, from 750 metres for coal mines and over 2 kilometres for uranium mines. The Mine Cage Every underground mine has mine shafts, and each has an indispensable function. Ventilation shafts clear the toxic fumes that are by-products of blasting and drilling. Recovery shafts carry the ores from the bottom of the mine to the surface. Access shafts carry personnel and equipment to and from the surface. All shafts have crucial components, one of the most notable are mine cages.

The mining business is a vast industry that it is divided into five segments: metal ore mining, non-metal mineral mining, coal mining, supporting activities, and gas and oil extracting. The requirements can differ greatly within each segment which emphasizes the need for custom-made equipment. For example, precious metal mining cars need to operate in different environments versus those used for mining nickel ore. Choosing equipment that would be compatible to a certain application and specific tasks can be a challenge especially when each mine is different. Fortunately, through modern technology and advances in engineering, custom-made mining cars and other equipment can be crafted to fit each mine’s needs. Materials Using the right materials for building mining cars is important to ensure efficient rail haulage workflow in a mine. If a mining car is not constructed properly to carry required loads, it could slow down the entire operation.
The equipment used by miners in Ontario are subject to constant friction, tension and compression, which means wear and tear on exposed parts. Continuous use of production equipment regardless of the condition of worn parts can have a huge impact on productivity. Besides failing to extract sufficient amounts of ore, they may eventually break down, resulting in costly downtime. Mining companies use different techniques to keep their equipment and machines in top condition amidst the pressure they are exposed to throughout each operation. Some of these are the same practices that help prolong the life of more common equipment such as automobiles.

Before a mining project commences, the site in question is thoroughly explored, entailing a series of lengthy and complex analyses and appraisals to determine the feasibility of the project and the most efficient process to implement. If the minerals are found to be deposited deep in the earth, the only viable option is developing an underground mining operation that involves the creation of a mine shaft. What is a mine shaft? A mine shaft is a is a vertical access hole that is several meters in diameter and stretches down to the location of the ore. It is where miners, supplies, equipment, water and air are conveyed to gain access to the ore. Ore is conveyed to the surface through mine skips that move up and down the shaft.

According to a recent article from The Guardian, Canada is currently the headquarters of more than half of the world’s publicly-traded mining companies. These companies have a far-reaching supply chain, having more than 8,000 mining projects across six continents that involve practically every aspect of mining (exploration, construction, production, and closure) and employ almost every piece of heavy equipment available (excavators, dump trucks, drills, mine cages, skips, and rail cars). One huge potential risk for these businesses is having projects that are located in developing countries where minors account for almost half of the local population—children below 18 who are prone to the negative effects of living so close to mines. To stave off these ill effects, a handful of Canadian mining companies are taking the initiative to study how to improve operations in a way that can benefit children in mining industries, and then implement the necessary changes.

Underground mining is the second oldest method of producing salt, next to the solar evaporation technique. Like most mines, salt mines employ large machines to travel through vast cave-like passageways performing various functions. Unlike most mines, however, salt mines are comfortable to work in (average temperature stays around 70° F all year round) and offer a safer work environment than usual. Salt mine in Goderich, Ontario Deep under Lake Huron lies the largest salt mine in the world. Some 500 miners work in the mine, often cited as a massive and almost pure deposit that experts predict will be able to supply 100 years of mining. Compass Minerals is the company in charge of the mine, and if predictions are on point, the company is set for profit for many years to come.
