WAYS TO PROTECT SURFACE AND SURFACE OBJECTS FROM UNCONTROLLABLE LEAKAGE OF MINE GAS TO THE SURFACE

Popis výsledku v původním jazyce

With gradual reduction of coal mining in the Ostrava Region, which began about twenty years ago, ventilation of mines finished as well, together will controlled methane extraction. Moreover, inappropriate liquidation of all pits, especially at the beginning of the mining reduction, resulted in the accumulation of mine gas in the underground space and their uncontrolled migration to the surface started. This has led to a significantly increased risk to civil and industrial buildings. To prevent this uncontrolled migration of mine gas, in particular methane, it was necessary to introduce a number of measures. One of them was the introduction of monitoring of mine gases at degasification wells. During active extraction, there was no need to solve this problem, because the main ventilation was realized using intensive suction method, which was later supplemented with a more intensive degasification. The main ventilation and degasification of mines created sub atmospheric pressure in the underground space compared to surface atmosphere, thus reducing the risk of uncontrolled leakage of gases to the surface.
