    Gasification – Any of various processes by which coal is turned into low, medium, or high Btu gases. Gathering conveyor; gathering belt - Any conveyor which is used to gather coal from other conveyors and deliver it either into mine cars or onto another conveyor. The term is frequently used with belt conveyors placed in entries where a number of room conveyors deliver coal onto the belt. Geologist - One who studies the constitution, structure, and history of the earth's crust, conducting research into the formation and dissolution of rock layers, analyzing fossil and mineral ******* of layers, and endeavoring to fix historical sequence of development by relating characteristics to known geological influences (historical geology).

    Geology - a science dealing with the formation of the earth and ore deposits. Gob - The term applied to that part of the mine from which the coal has been removed and the space more or less filled up with waste. Also, the loose waste in a mine. Also called goaf.[IMG]file:///C:/Documents%20and%20Settings/Administrator/Desktop/معجم%20هندسة%20التعدين/Mining%20Terms%20-%20G_files/highkeep_vue.jpg[/IMG]Global climate change – This term usually refers to the gradual warming of the earth caused by the greenhouse effect. Many scientists believe this is the result of man-made emissions of greenhouse gases such as carbon dioxide, chlorofluorocarbons (CFC) and methane, although there is no agreement among the scientific community on this controversial issue. Grade - the value of an ore Grain - In petrology, that factor of the texture of a rock composed of distinct particles or crystals which depends upon their absolute size.[IMG]file:///C:/Documents%20and%20Settings/Administrator/Desktop/معجم%20هندسة%20التعدين/Mining%20Terms%20-%20G_files/polished1.jpg[/IMG]Grizzly - Course screening or scalping device that prevents oversized bulk material form entering a material transfer system; constructed of rails, bars, beams, etc.[IMG]file:///C:/Documents%20and%20Settings/Administrator/Desktop/معجم%20هندسة%20التعدين/Mining%20Terms%20-%20G_files/Grizzly.jpg[/IMG]Ground control - The regulation and final arresting of the closure of the walls of a mined area. The term generally refers to measures taken to prevent roof falls or coal bursts.
    [IMG]file:///C:/Documents%20and%20Settings/Administrator/Desktop/معجم%20هندسة%20التعدين/Mining%20Terms%20-%20G_files/props1.gif[/IMG]
    Ground pressure - The pressure to which a rock formation is subjected by the weight of the superimposed rock and rock material or by diastrophic forces created by movements in the rocks forming the earth's crust. Such pressures may be great enough to cause rocks having a low compressional strength to deform and be squeezed into and close a borehole or other underground opening not adequately strengthened by an artificial support, such as casing or timber. Grout - a filling agent inserted by pressure into loose and broken rock or ground Gunite - A cement applied by spraying to the roof and sides of a mine passage.

    Incline - Any entry to a mine that is not vertical (shaft) or horizontal (adit). Often incline is reserved for those entries that are too steep for a belt conveyor (+17 degrees -18 degrees), in which case a hoist and guide rails are employed. A belt conveyor incline is termed a slope. Alt: Secondary inclined opening, driven upward to connect levels, sometimes on the dip of a deposit; also called "inclined shaft".

    Not mining related but applicable.
    Indicated coal resources – Coal for which estimates of the rank, quality, and quantity have been computed partly from sample analyses and measurements and partly from reasonable geologic projections. The points of observation are ½ to 1 ½ miles apart. Indicated coal is projected to extend as an ½ mile wide belt that lies more than ¼ mile from the outcrop or points of observation or measurement. Inferred coal resources – Coal in unexplored extensions of the demonstrated resources for which estimates of the quality and size are based on geologic evidence and projection. Quantitative estimates are based largely on broad knowledge of the geologic character of the deposit and for which there are few, if any, samples or measurements. The estimates are based on an assumed continuity or repletion of which there is geologic evidence; this evidence may include comparison with deposits of similar type. Bodies that are completely concealed may be included if there is specific geologic evidence of their presence. The points of observation are 1 ½ to 6 miles apart. In situ - In the natural or original position. Applied to a rock, soil, or fossil when occurring in the situation in which it was originally formed or deposited.[IMG]file:///C:/Documents%20and%20Settings/Administrator/Desktop/معجم%20هندسة%20التعدين/Mining%20Terms%20-%20I_files/Tusk_in_situ.jpg[/IMG]Intake - The passage through which fresh air is drawn or forced into a mine or to a section of a mine.
