Abstract. Subject of the study was regularity of the stress-strain state changing in different supporting structures in the process of winning operations, and impact of these structures parameters on the gate-road contour displacement and enclosing rock deformation. Procedure of the  study included determination of nature of the stress re-distribution along the width of the supporting wall and measurement of the wall vertical deformation, depth and rate of the bed-roof separation and floor swelling. Rational geometric, strength and deformation parameters were validated for the supporting structure. Basing on the finding, scheme of the gate-road support, which includes concrete packed wall, breaker props and system of the roof and floor bolting for the working coal seam, is recommended as the most effective one in terms of technology and economy.
Keywords: gate-road support, stress-strain state of supporting structures, deformation of the gate-road contour and enclosing rocks.
