Abstract
Description
Currently, coal is one of the main fuels for industry, the national economy and thermal power plants. Coal is a solid fuel that must contain enough heat to make it economically profitable to use, as well as in the incineration of which no man-made waste is released. In this work, the physical and mechanical properties and chemical composition were studied, as well as the microscopic analysis and enrichment of high ash coal by gravity method, which is mined in «Angren» section. Man-made waste that is not recycled after the use of coal causes damage to the environment by clogging it, but do not forget that this waste reduces the calorific value of the fuel. Thus, coals containing various impurities do not provide effective calorific value, which increases economic costs as well as reduces our natural wealth.
