Abstract

Heavy rock falls of coal roof cause increased pressure load on powered roof support systems during the mining of first layers in seams III and IV-V of Tomusinsky coal field. Moreover, the complex morphology of the seam creates additional difficulties in downward working of seam layers. All these factors call for validation of thick flat-lying coal seams mining methods that involve longwall face layered floor mining as an alternative to any kind of artificially induced weakening of coal roof.
