Coal Mining Terminology
Being a universal player in mining and exploration, the name of Rachana Global can best be associated with all the coal mining terminology. Believing in undying dedication for constant growth, Rachana Global leverages its mining expertise to offer outstanding services for coal exploration and mining.
Coal: A solid, brittle, more or less distinctly stratified combustible carbonaceous rock, formed by partial to complete decomposition of vegetation is known as coal. It varies in color from dark brown to black. It is not fusible without decomposition and is very insoluble.
Coal Extraction: The process of mining and removal of coal from the naturally occurring coal deposits is called as coal extraction.a
Coal reserves: Measured tonnages of coal that have been calculated to occur in a coal seam within a particular property are known as Coal reserves.
Coal mine: Coal mine is an area of land and all structures, facilities, machinery, tools, equipment, shafts, slopes, tunnels, excavations, and other property, real or personal, placed upon, under, or above the surface of such land by any person, used in extracting coal from its natural deposits in the earth by any means or method, and the work of preparing the coal so extracted, including coal preparation facilities.
Coal mining: The technical and mechanical process of removing the coal from the earth and preparing it for the market is called coal mining.
Coal mining activities: The activities essential for mining coal from the underground deposits of coal are usually referred as coal mining activities.
Coal washing – The process of separating undesirable materials from coal based on differences in densities is called coal washing where all the heavier materials sink in water but as coal is lighter it floats.
Blending of coal: Because of limited availability of good quality coking coal, the Indian Steel plants use a optimal Blend of the 3 or more varieties of coking coal to compensate for the lack of individual coals with the necessary properties.
Coking Coal: Coking coals are those varieties of coal which on heating in the absence of air (process known as Carbonisation) undergo transformation into plastic state, swell and then re-solidify to give a Cake. On quenching the cake results in a strong and porous mass called coke.
Evaluation – The work involved in gaining knowledge of the size, shape, position and value of coal is evaluation.
Surface mining: Surface mining is a type of coal mining in which soil and rocks overlying the mineral deposit are removed.
Open pit mining: The process of extracting minerals from surface excavations is called as open pit mining. It is a type of surface excavation which often takes the shape of an inverted cone.
Underground mining: A mineral extraction technique consisting of subsurface excavation with minimal disturbance of the ground surface. Underground coal mining is the extraction of coal from below the surface of the earth. The coal is worked through tunnels, passages, and openings that are connected to the surface for the purpose of the removal of the coal.
