Essay

The arguments of an improved sealing technique of a fasten mine workings space are advocated. The structurally – technological schema of a sealing, based on the seal shell with variable deformation of a support contour is justified. The significant dependence of a tension field in all strata of a support and on it contour, a deformation modulus disteibution function of a sealing stratum and its rational value for supply the strength balance of supporting members – reaching of maximal bearing capacity are installed. The operating graphic account method of multiplayer support bearing capacity is designed and recommendations at the choice of rational seal solution compositions is introduced into engineering specifications. The basic contents of operation are published in monograph and five papers.
