Sharp cutter picks attach to the head and extract coal from the coal seam, working within the machine's minimum and maximum cutting height. Some models have a dual gathering head system to increase development rates. Both single and double cutter head systems lift to reach their maximum cutting height.
A mining accident is an accident that occurs during the process of mining minerals or metals. Thousands of miners die from mining accidents each year, especially from underground coal mining, although accidents also occur in hard rock mining is considered much more hazardous than hard rock mining due to flatlying rock strata, generally incompetent rock, the presence of methane gas ...
Mining is one of the most vital components of modern society due to the use of mined minerals in almost every consumer product. Additionally, 50% of the nation's energy comes from coal or nuclear power that uses uranium. To support this need for modern equipment, mines are found in all 50 states, including our home state of Nevada.
Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.
