    Zagrożenia wodne w kopalniach węgla kamiennego w Górnośląskim Zagłębiu Węglowym w dobie restrukturyzacji górnictwa
    (2007) Bukowski, Przemysław
    The progressive process of mines abandoning in the USCB from early 90's caused the formation in mine workings of water reservoirs with a capacity of each of millions m3 of retentioned water. Despite the observed decrease of incidents that result from the water hazard during last decade, the water reservoirs that come into existence in mine workings of abandoned mines endanger and will cause even greater hazard for conducted and planned mine workings. Their influence in conditions of various properties of geological environment entail the necessity of changes in an attitude to the assessment of the scale of water hazard and their prognoses, what was presented in general in the article.
