Coal preparation. As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment and miners.
Coal gasification is the process of producing syngasa mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as quot;town gasquot;.Coal gas is combustible and was used for heating and municipal lighting, before
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a ''pit'', and
Materials in your process are on the move. Transporting raw materials, feeding additives into a process, loading out finished products. Material handling requires speed and precision provided by Siemens process instrumentation. Crusher level control Crushers are harsh environments for sensors
#0183;#32;Coal needs to be stored at various stages of the preparation process, and conveyed around the CPP facilities. Coal handling is part of the larger field of bulk material handling, and is a complex and vital part of the CPP.. Stockpiles provide surge capacity to various parts of the CPP. ROM coal is delivered with large variations in production rate of tonnes per hour (tph).

Many coal beds are very near the grounds surface, and about twothirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our coal reserves. Due to growth in surface mining and improved mining technology, the amount of coal produced by one miner in one hour has more than tripled since 1978.
#0183;#32;Process instrumentation plays an essential role in keeping manufacturing equipment running productively, As a global frontrunner in the exportation of coal, How to make Australian mines more efficient through effective process instrumentation.
Coal Washing. Coal washing is a process designed to separate the coal particles based on size, density and shape. Achieved by allowing the coal to settle in the wash fluid. Continuous Mining. Continuous Mining is an underground method of extracting coal. The process utilises a machine that is capable of handling the entire extraction process.
#0183;#32;Process instrumentation solutions for gold mines In Australia, gold is the second largest industry for Vega, with the company serving around 150 mines for the precious metal. Within the gold industry, the companys two biggest markets are level and pressure measurement.
Over the past 60 years, Fluor has developed extensive capabilities in the development of coal projects and has provided study and engineering, procurement, fabrication, construction (EPFC) and maintenance services to coal projects in other countries including Botswana, Canada, the United States and Columbia.
The motors used in Coal Mining Process Diagram can be classified into two groups. The motors in the first group are drives for mine auxiliaries such as compressors, pumps, etc. The motors of the second group are used to drive the cutters, drillers, etc., which are directly used in the process of mining.

Mine development. Coal can be extracted from the earth either by surface mining or underground mining. In openpit coal mining, a pit is dug in an area and this pit becomes the openpit mine, sometimes called a mines can expand to huge dimensions, until the coal deposit has been mined or the cost of transporting becomes too great.
