Strategy of longwall preparation and of the possibility of support strengthening in the coal mines with the rock burst risk
 Ptáček, Jiří ; Konečný, Petr ; Šňupárek, Richard ; Koníček, Petr
The contribution presents conclusions of the research project called Miners protection against rock burst in the gates and measures to avoid them after checking the rock burst danger, supported by Czech Mining Authority. The results of research on the reinforced break through support and research on the way and strategy of longwalls driving in the conditions of rock burst danger are described.

Evaluation of subsidence caused by application of single-entry room-and-pillar mining method with stable pillars between mined out drifts using the Continuous Miner Technology with full roof bolting. Stage 2 – Development of model for stable pillar dimensioning for single-entry room-and-pillar mining method with Continuous Miner Technology and calculation of surface deformation
 Konečný, Petr ; Byczanski, Petr ; Koníček, Petr ; Ptáček, Jiří ; Šňupárek, Richard ; Velička, Vilém ; Zeman, Vladislav
The model solution of stable pillars dimensioning for single-entry room-and-pillar mining method with Continuous Miner Technology is described. Consequently, the parameters of subsidence trough are calculated as an example caused by application of that technology in selected conditions of Ostrava-Karviná Coal Basin.
