What does a Miners do?
Miners are valuable members of the work force that engage in the risky but essential task of extracting minerals and other important substances from the earth. The materials that are harvested are used to provide a number of goods and services to the buying public. In some cases, the miner works with highly technical equipment, and in other situations, he might perform his duties with the same simple tools that have been used for centuries.
Perhaps the most commonly recognized type is the coal miner. Coal mining involves extracting coal from underground mines, a task that is carries a high degree of risk. Historically, few precautions were made to protect these miners safe from physical danger, including respiratory problems. The second half of the 20th century saw a number of reforms in the industry, however, including the addition of protective gear that serves to minimize the chances for ongoing health issues.
Mining in general is a dangerous profession. Much of the actual work takes place in the mines, where there is always the chance of exposure to underground gases, shaft failures, and other dangers. Part of the training process for a miner today includes working with life saving equipment, as well as learning how to deal with emergency situations that arise in the mines from time to time.
What does a Metallurgist do?
A metallurgist is an engineer who specializes in studying the properties of metals. Metallurgists may also have training in geology, as metals extraction can be heavily involved with geology and an understanding of geology can be important to some people who work with metals. Metallurgists can be found working in a wide variety of settings all over the world, and employment prospects in this field are generally quite good.An extraction metallurgist focuses on getting useful metals out of ores. He or she may also be interested in the process of purification and alloying, working with metals to develop well-known products and developing new metals which can be applied to a range of engineering problems. Chemical and physical metallurgists study the chemical and physical properties of metal, looking at things which stress metal, such as fatigue, corrosion, and temperature changes. A process metallurgist specializes in turning metal into something useful, and exploring the ways in which metal products can be manufactured and utilized.
To become a metallurgist, it is usually necessary to attend a training program which offers opportunities to people who are interested in careers in metallurgy, ranging from a technical school which teaches people forging techniques to a college or university engineering program. Some metallurgists may also acquire their skills on the job, working under supervision initially and eventually independently, although this method of learning metallurgy is less common.
What does an Electrician do?
An electrician specializes in the installation, operation, repair, and maintenance of electrical systems. These systems include wiring, circuit boards, and electronics. This profession is incredibly varied, and in some parts of the world it can pay very well, due to the three to five year training period required for an electrician to be successful. Consumers interact with the work of electricians every day in communities with electricity, and many people have a preferred electrician for electrical repair around homes and businesses.Some people like to distinguish between an electrician and a lineman, depending on regional nomenclature. In this sense, an electrician works on internal wiring in homes and other buildings, while a lineman works on outside electrical lines and in power generation facilities. Due to the much higher currents involved in this work, being a lineman can be very dangerous, especially when linemen are sent out to respond to downed power lines and other emergencies which can occur in inclement weather.
