Abstract

The aim of this study is to work out a project for an anti-rockburst prevention for the future coal face No. 22 3756 in the block No. 22 of the mining field Doubrava in the location of the mine ČSA Karviná. The naturally-geological conditions of the rock massive, in which is the projected coal face located and will be extracted, have been described here. Furthermore, I have determined the methods of regional and local prognosis, and classified the coal face according to the level of the rockburst hazard together with the proposed active and passive means of the anti-rockburst prevention. Monitoring the staff working in the determined endangered area is a new ISI method.
