TERMINATION OF MINING OPERATIONS AND OTHER FACTORS AFFECTING MINE GAS LEAKAGE

Popis výsledku v původním jazyce

As a result of termination of mining operations, we are facing many risks incurred in its context. The most serious ones include uncontrollable leakage of mine air to the surface resulting in significant risks to the public and civic buildings. Possible gas leakage can be caused either by natural conditions or artificial intervention. The space between the surface and the excavated area overburden is largely discontinuous, and it is disrupted by a number of surface discontinuities caused mainly by undermining, tectonic faults, mining activities or interventions in the upper part of the earth surface not directly related to mining activities. This results in the formation of large, virtually undetectable hidden network of the areas with potential mine gas leakage to the surface. The actual risk of mine gas leakage to the surface can be evaluated as a risk of two types if the leaking gases are explosive, or if they can become explosive, or the mixture composition is non-explosive, but it leaks to the surface and can result in non- breathable environment. The different characteristics and effects of the mixture must be taken into account, points of mine gas leakage to the surface must be appropriately allocated, and appropriate technical measures have to be made.
