The thesis is dedicated to the questions of substantiation the rational parameters of iron ore mining methods in weak host rocks for mining-geological conditions of Pivdenno-Bilozerske deposit. As a result of physical modeling and industrial studies the technological solutions for working-out of the deposit's hanging wall chambers in weak host rocks are proposed. Rational parameters of mining methods in the influence zones of weak host rocks are substantiated that allows to keep adopted parameters of footwall chambers and requires the decrease of chambers parameters located near the deposit hanging wall. New solutions of parameters rationalization of hanging wall chambers in weak host rocks that are introduced during iron ore recovery on "Ekspluatatsiyna" mine of CJC "ZZRK". The economic effect made up about 3,465 mln. UAH.
