7. 7 2. Box cut Box cut is the initial/first cut given for the physical development of a mine. The name 'Box cut' has been attributed to this cut as this cut generally looks like a top open box having an inclined floor and walls on three sides (front wall and two side walls) in case of opening up of subsurface deposits.

The chemical composition of coal has a strong influence on its combustibility. The properties of coal are broadly classified as 1. Physical properties 2. Chemical properties Physical Properties Heating Value: The heating value of coal varies from coal field to coal field. The typical GCVs for various coals are given in the Table
Formation • The transformation of the vegetable debris to coal takes place in two stages: (a) Biochemical or peat stage: During this stage, the plant materials were attacked by various micro organisms. (b) Chemical stage or metamorphism: In this stage, the peat deposit buried under sedimentary deposits lose moisture and volatile components under the effect of high temperature and ...
Properties of Coal • Coal properties are evaluated by different methods. • The most commonly used methods are Proximate and Ultimate analysis of the coal. • Proximate analysis gives the Moisture, Ash and Volatile matter, while the Fixed Carbon is found by difference. • Ultimate Analysis gives the elemental composition of the coal.

31. 23 Experimental procedure: The 1 gram of coal pallet of 72 mesh (BSS) is taken as the sample for the experiment. The vessel is filled up to the neck with quinoline and placed over the electric oven in a fume chamber. The oven temperature is controlled to boil the quinoline ( at 230O C).
Other articles where carbonization is discussed: chemical industry: Benzene: was obtained from the carbonization (heating) of coal, which produces coke, combustible gas, and a number of byproducts, including benzene. Carbonization of coal to produce illuminating gas dates back in England to the very early years of the 19th century. The process is still employed in some countries, but.
