Object of the research. Decrease of preparatory working resistance in the zones of techno-genetic vibration influence. Aim of the research. Substantiation of preservation means of section working resistance in the zones of techno-genetic vibration influence. Methods of the research: natural and analytic researches. Modern equipment 3YA-98 and low frequent vibration sensors were used. Distinctions of displacement on the edge of working were examined. Vibration spread mechanism in the system "shaft lining - surrounding rocks" was examined also. Was discovered dependence of the size of single displacements during starts and stops of conveyor engine from basic factors. New ways of preservation of workings stability were developed and introduced. Annual economic effect achieved 15 thouzand hrn. The spere of results application is deap coal mine
