FEATURES OF SAFE DEVELOPMENT ENSURE OF HAZARDOUS GAS-DYNAMIC PHENOMENA DEPOSITS

Geomechanical methods to control the deposits of dangerous gases are developed. Conditions for the formation of through and closed local gaz channels are established. It allows choosing efficient positioning of degasification wells, to find and apply the optimal settings. A correlation between residual pressure of methane after degassing events and horizontal deformations of the dangerous layer is holding. Using the results of researches will allow to prevent accidents or to reduce their negative impacts and to increase the efficiency of methane utilization.
