NEW RECOMMENDATIONS IN THE AREA OF PREDICTION AND PREVENTION OF ROCK AND GAS OUTBURSTS IN THE CZECH REPUBLIC

Abstract

Rock and gas outbursts still represent one of mining risks that has caused considerable loss of life of mine workers and economic losses. With reference to the fact that outbursts have occurred and will continue to occur, it was necessary to make an analysis (Hudeček, 2008) of previous outbursts and existing and previously acquired parameters of prediction and prevention methods. In the article, the authors present recommendations and proposals for changes in the area of rock and gas outburst prediction. These proposed changes should be reflected in the increased efficiency of control of this anomalous geomechanical event.
