Due to excessive heat and friction involved in mining, corrosion and wear is one of the most prevalent problems in the industry. Millions are lost due to halted productions, 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 minimise losses for 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. Choice of Material The best way to ensure that parts will hold up against the pressure is to make them with excellent materials. Aside from strength, dent resistance, toughness and ductility, heat resistance should be a top characteristic for materials. Crafting parts using such materials will help improve its ability to resist breaking or wearing down under extreme temperatures.

Mining is a millennia-old industry that has seen many advancements. Throughout the years, new equipment have been designed to make mining more efficient and safer for workers. Perhaps one of the most problematic 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 various machinery take considerable wear and tear. When one essential equipment is compromised, it could cripple the entire process. Maintenance Challenges Most mine haulage equipment are designed for a mine’s specific needs. As a result, each equipment is unique and require specific measures in order to keep in good shape. Neglected, faulty machinery can lead to accidents and injuries to their operators or other various mine workers. Custom made equipment also require specially crafted spare parts that would most likely be available where it was made in the first place.

For mining companies specialising in underground mining, they know that each mine is unique, since each of these deposits have their own set of geologic, geochemical, and geophysical characteristics. The same holds true for mine shafts and mining cages, and though these are built in accordance to applicable standards and regulations, these are ultimately designed to meet the needs of the operation and the site. Lost Revenues due to Unmaintained Cages Regardless of how the shafts and cages are built, these are still subject to the forces of gravity, corrosion, and age. Ignoring these elements and letting them accumulate on the mining shaft can cause an unplanned shutdown, which can have a negative economic impact on a mining company.

While numerous mining companies still conduct surface mining in their sites, the costs that come along with it may become prohibitively expensive on the long run. 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 companies seeing a larger strip ratio can then turn to underground mining as a more cost-efficient and land-friendly investment. The Objective of Underground Mining What underground mining does is to extract the ore from the earth in a safe and economical way without producing too much waste. Underground mining is particularly feasible for mining companies specialising in the extraction of minerals, rocks, and precious stones that are found far beneath the ground. This is also an effective option for companies mining rocks or minerals on the side of a mountain.
