Terykon - blade, artificial mounds of waste rock extracted by underground mining deposits of coal and other minerals, the mound of waste or toxins from various industries and solid fuel burning.
Inside the heaps of mines and ore-enrichment plants often occurs occurrence of various anthropogenic processes pirometamorfizma:
coal combustion (oxidation zone of firing mode)
pyrolysis of coal (zone reductive roasting at T = 800-1000 ° C)
dehydration reactions of layered silicates that are the result of massive evaporation of water and the removal of fluorine and chlorine in the initial stages of burning (T = 600-700 ° C)
decomposition of carbonates with the removal of CO and CO2 and the formation of periclase, lime and ferrites (T = 600-800 ° C)
local melting to form a vitrified clinker and bazytovyh paralav (T = 1000-1250 ° C)
These processes lead to a radical change in the phase composition moldboard mass. There have been cases of explosions teryk ones as a result of these processes.
In Terykon held gardening (reclamation) - vysadzhayut acacia and various other vegetation.
In the process of land reclamation piles are subject planting and afforestation. They were seated in a large number of trees with a view to stop the destruction teryko bers from the action of destructive factors.
At first glance, nothing special - well, were stones in a pile, it is clear that the place occupied - now there is nothing to grow and did not build. Mother nature does not like when her routine procedure violated. And then there are disasters.
This accident occurred in 1966 at the mine. Dimitrova, near the Ukrainian city Krasnoarmiysk. As usual, around a large heap gradually appeared settlement. No permission to put houses here did not give - such villages in the mining regions were something common and are often called Nahalovka.A number of peacefully standing heap and occasionally pokuryuvav smoke, break here and there among the hills. It so happened that one of the spring, during Victory Day, charged rains. And of heap landslide - part slid down a slope. I exploded - sudden changes in temperature and water trapped in the burning bowels caused an explosion. The village was destroyed completely, killing more than 60 people, the number is not specified - is an assessment by the remains of people who were burned alive, how many residence really gross - no one knew.
After this incident, waste heaps took seriously - first, adopted a program of allocation of new housing during relocation of heaps, second - took up the same piles. Top of heap endured, turning them into flat uplands, Hot attempted to extinguish piles, old and small hills trying rekultyvuvaty - green the trees and bushes. But at every stage of the struggle people faced with big challenges.
