During the coal mining process, first, bulldozers clear and level the mining area. The topsoil is removed and stored for later use in the reclamation process. Many small holes are drilled through the overburden (dirt and rock above the coal seam) to the coal seam. Each is loaded with explosives which are discharged, shattering the rock in the overburden. Giant power shovels or draglines clear away the overburden until the coal is exposed. Smaller shovels then scoop up the coal and load it onto trucks, which carry the coal to the preparation plant.
Because coal was the basic energy source that fueled the Industrial Revolution, the resulting industrial growth supported the large-scale exploitation of coal deposits. Fifty years ago when most coal mining was done manually, underground mines accounted for 96 percent of the coal produced each year. Today, almost 60 percent is produced from surface mines. The mining of coal from surface and underground deposits today is a highly productive, mechanized operation.
The coal utilization plays a tremendous role in promoting socio-economic, and also has significant impact on the environment. Gangue and coal bed methane, the main waste generated by the coal development process, have long been regarded as hazardous substances and severe gas. In terms of the growing energy shortage situation, people gradually realized these wastes are still available for creating value. Therefore, raymond mill and broken equipment get vigorously applied and create considerable economic benefits for users.
Coal mobile crusher means a mobile crusher special for coal mining or coal processing. Also, we can call it mobile coal crusher or coal portable crusher. Maybe they will be named different names, but they have the same function. This coal crusher concept is fully adaptable to all mobile crushing needs; it sets up a new range of business opportunities for contractors, recycling and mining applications. It can eliminate the obstacles of the crushing places and circumstances, and offer the high efficiency and low cost project plants for the clients. To the client, Cathay coal mobile crusher is the best choice.
After coal comes out of the ground, general it has been processed. However, the transports cost is very high, and the scene condition is difficult for fixed crushing plant. At this present, mobile crushing plant appear. It can eliminate the obstacles of the crushing places and circumstances, and offer the high efficiency and low cost project plants for the client. So, many miners use mobile coal crusher to process coal. With 30 yearsÂ’ experience in designing and making crushers, coal mobile crusher has been exported to many countries and received high popularity.
