The largest volumes of waste are accumulated in mining (coal waste heaps, waste dumps) and processing industry (especially in metallurgy and chemical industry).
In the extraction of coal annually to the surface from the depths raise about 1 billion m3 of waste rock. From it form piles that take up thousands of hectares of fertile land.
With the extraction of Donetsk the amount of waste coal gangue increases annually by 10% for operation at a greater depth with less powerful coal seams. These wastes can be used to fill the voids developed mines, construction material, fertilizers, road construction.
For road construction 70% barren rock, for cement production – 24%, gravel 30%, and ceramics – 16%, sand-lime brick is 10%. However, unless you use no more than 5% of such waste.
