Abstract. The authors consider possibility to perform mining operations in zones with geological disturbance in gypsum deposits. Special attention is drawn to estimate of long-term stability of the roof coals in tunnels with geological disturbance. Typical variants of the roof coal structure are considered  for undisturbed areas and areas with geological disturbance in tunnels of the gypsum mines. Dynamics of block structure formation in the roof coal at long-term exploitation of the tunnel was analyzed, and the most typical natural defects in the roof coal were specified. Impact of a factor complex on the roof coal operating safety is considered. An analytical estimate of long-term stability of the roof coal is presented for three rated cases. The findings are used for choosing proper parameters of the mining system in disturbed zones.

Keywords: gypsum mines, roof, geological disturbance, long-time stability.
