摘要：Longwall salvage activities at JSC SUEK-Kuzbass underground coal mines may experience unforeseen delays. To determine the causes of the delays in the salvage activities, we have considered various factors. Firstly, we have analyzed the effect of the longwall face width on the duration of salvage activities. We have proved that this factor does not have a statistically significant effect on the duration of salvage activities. We have established that the duration of the salvage activities is determined by the location of the salvage chambers relative to the pillar and the previously extracted panel. In the event that contiguous previously extracted panel is located near the salvage chamber, the salvage time is doubled on average.
