Plán otvírky, přípravy a dobývání pro oblast 40. sloje 9. kry na Dole Darkov, OKD a.s.

Abstract

In the present work is a proposal of opening, preparation and extraction of coal block 40th seam in the 9 floe Mine Darkov silicon for future contol. The work is characterized 40th seam including geological and geomechanical conditions. Suggests a way of road heading with respect to angle conditions and deploy suitable road heading techniques in the preparation of future longwall block. Solves the time of preparation and continuity of longwall mining 40 902, 40 903, 40 906. It is a proposal of technology for longwall mining 40 903, including basic precautions against the risk of mining coal face. Proposes the most advanced techniques deployed OKD as of investment projects of modernization POP 2010. Further processed longwall ventilation in 40903 and calculation of gases exhalations.
