ABSTRACT

A B S T R A C T : Coal is a fuel, which is used by all the leading countries in the world to strengthen

their national power systems. Moreover, the price for coal is usually significantly lower than those

of gas and petroleum products. That is why it is economically more feasible to use coal rather than

other types of fuel. It is not accidental that the share of coal in power generation in the U S A , a coun-

try with the most strict market economy, is equal to 52%, in Germany, a country with a socially

oriented market economy - 54%, in China - a country with a transition economy - 72%.
