Object of the research in this article is the processes of safety and energy efficiency control at hydrocarbon gas recovery and utilization during the coal extraction and development of mines. Subject of the research is criterion of safe, trouble-free and efficient operation of equipment and informational and resource-saving technology for the hydrocarbon gases recovery form the boreholes and mines and their further utilization. The structural and technological scheme of the mine trigeneration complex was developed on the basis of the studied technical solutions and results of the research works. For the complex design, the authors used an algorithm developed for uninterrupted control of boilers with using method of mathematical modeling of dynamics of its components and technical and economic aspects of the cogeneration of hydrocarbon gases. This algorithm provides issuing of preventive actions simultaneously in all channels of information input with a disturbing process of steam load changing. Besides, parameters were determined and mnemonic schemes of explosion safety were developed for preparing gases for starting boilers and using the protection systems for preventing the spread of toxic gases and for uninterrupted operation. Additional input parameters are presented in the article: smoke gas consumption, methane concentration in the methane-air jet, and oxygen and methane concentration in the isolated mine workings, gas distribution point and boiler entrance. The health and safety criteria were established. They are calculated on the basis of new parameters that form control actions, which ensure explosion safety, trouble-free operation, and labor protection during the operation of the boiler unit. Further, on their basis, information tools were developed for controlling the stations of the boiler units, and safety criteria and conditions were established, which influenced on the reduction or increase in the frequency of the drive power used in the smoke exhaust system.
Keywords: mining safety, automated systems, visualization of three-dimensional models, control of geotechnical systems, boilers, coal gas, structural and technological scheme, trigeneration complex, hydrocarbon gases.
