The present thesis deals with the solution of the topical scientific task of increasing both the efficiency and the provision with the stability in exploiting the degassing system for the worked-out close seams due to the validation of the topological parameters of degassing bore according to the well bottom’s position data and the choice of the necessary degassing parameters by means of solving the combined equations that describe the degassing network exploiting. The methods of methane-air mixture low rate estimating on the hollow sites of degassing system together with the known wastes of the drawn-out methane values, the methods of estimating the wastes of the drawn-out methane values together with the air inflows to the bores, the methods of estimating the discharge on the bores’ mouths on the bore wells included to the degassing system together with using the dependencies of the methane-air mixture and methane flow rates, got as the result of the examinations, the methods of estimating the distance between the bores together with taking into account the methane concentration along the length of the pipeline were investigated.
