The paper outlines the main objectives of the method used for assessment of rockburst hazard during longwall mining operations taking into account factors expressing the confined work conditions. Relying on analytical approach, the conditions are examined that are likely to trigger the rockburst occurrence along the face, with regards to the location of cross-cuts and taking into account the presence of past excavation and geological disorders in the overlying strata. Simulation data apply to three cases of model loading, representing the impacts of residual pillars, gobs surrounded by undisturbed blocks of coal and the presence of faults, whilst the procedure involves five possible locations of opening-out cross-cuts in relation to charact...
