Operation technique to mine thin seams with worked-out area stowing

Abstract

The monograph concerns substantiation of basic parameters and application area of thin coal seam mining with the worked-out area stowing by means of undercut rocks. As a result of the studies, regularities of changes in stress-strain state of rock mass depending upon operational parameters of mining procedures while the worked-out area stowing. The opportunity to use rocks of Western Donbas as stowing material has been substantiated. Basic design features of winning- stowing systems have been determined; operation schedules to mine thin seams with stowing for mines in Western Donbas have been developed. The monograph is meant for students, engineers and technicians, academics, scientific- research institutes, and project organizations of coal industry.
