Problems of using coal mining waste

The coal industry is one of the leaders in terms of waste generation in industrial production. In 2017, 3.6 billion tons of wastes were generated in the coal industry, more than 99% of which belong to the 5th class of hazard. The level of coal industry waste utilization is about 50% of the generated waste. At the same time, the amount of generated waste increases annually, with a constant increase in coal production volumes. This means a constant increase in the total amount of coal industry waste in external rock dumps, sludge collectors and tailing dumps. This leads to the development of a set of environmental problems. The use of production wastes is the main way to reduce their negative impact on the environment. In article the basic problems of use of a mineral waste of the mining and processing coal industry are considered. The world and domestic experience of use of a waste of coal mining industry is analyzed. Deficiencies of the current legislation, hampering application of resource-saving and nature protection technologies are considered. According to the authors of utilization of mineral wastes of extractive and processing industries and solid fuel energy are offered. Namely — development and approval of methods of complex estimation of possibility of use of a waste, development of recommendations on use of mineral wastes of extractive, processing industry and solid fuel power engineering in a bookmark of the exhausted spaces and modification of the current legislation.
