Influence of mining and geological conditions on the dynamics of roof collapses during layer excavation of potash beds
Abstract
The peculiarities of emergency collapses of the main roof during layer excavation of the Third potash layer were considered. Preliminary analysis of mining and geological conditions of their occurrence was carried out. The parameters of the immediate roof influencing the collapse intensity were revealed. Using Fisher's criterion, a "dynamism criterion" was found to assess the danger of different parts of the mine field.
