Open Pit and Underground Mining of Coal price for sale in Tanzania In coal mining, the coal mining method can be divided into two styles: open pit and underground mining of coal.Open Pit and Underground Mining of Coal price for sale in Tanzania  As a principle, open-pit method is considered to be much more approvable and dominant than Underground, especially in recovery, production capacity, grade control and cut off grade, ore lose and dilution, flexibility, safety, and so on. Even though, underground mining is more agreeable from environmental and social considerations. As well as, in special condition due to ore deposit geometry and increasing of deposit depth, underground methods must be adopted. Lots of deposits can be wholly mined with open-pit method, while others must be worked underground from the very beginning. is a professional coal mining project designer, who can supply clients excellent solutions and high quality machines with best service Open Pit and Underground Mining of Coal price for sale in Tanzania.

Open-pit coal mining

Open Pit and Underground Mining of Coal price for sale in Tanzania Open-pit coal mines are used to exploit low grade, shallow ore bodies but with greater coal mining rate. The coal mining rate is greater than 20,000 tonnes per day (TPD), but it is usually much greater. Some open pits operate at a rate of more than 100,000 THD.

Open pit coal mining results in two waste streams: waste stone which contains no economic quantity of minerals but which must be removed to gain access to the orebody, and tailings which are produced by a mineral separation process in processing plant. The mining rate includes the mining of both waste and ore.

Open Pit and Underground Mining of Coal price for sale in Tanzania Open-pit coal mining is non‐selective – all high and low grade zones of the orebody would be mined. The critical design issues of an open pit mine are: location of haul roads, equipment – size of trucks and fleet, pit slope angle and stability, control of water.

Underground coal mining

Underground coal mines are used to exploit high grade, deep ore bodies. Longwall coal mining is a highly mechanized underground mining system for mining coal. A layer of coal is chosen and blocked out into an area known as a panel. A typical panel might be 3000 m long by 250 m wide. Passage path would be excavated along the length of the panel to provide access and to place a conveying system to transport material out of the mine. Entrance would be constructed from the passage path along the width of the panel. The longwall system would mine between entry tunnels. Extraction is a nearly continuous operation involving the adoption of self‐advancing hydraulic roof supports usually called shields, a shearing machine, and a conveyor which runs parallel to the face being mined. A typical configuration of a longwall coal mining system is illustrated below on the left.
