Features of thermodynamic processes in underground degasification pipes made of composite materials in coal mines
The article is devoted to peculiarities of thermal processes in systems of underground degasification pipelines using pipe made of composite materials. In today’s environment of mining systems in underground coal mines have found the use of pipes made of fiberglass, thermal and physical characteristics which differ substantially from steel pipes. These differences have an impact on thermal and hydrodynamic regimes of motion of a methane-air mixture through an underground vacuum pipeline. The specificity of the process of heat transfer that occurs during transportation in underground vacuum pipeline methane-air mixture from the wells to the surface shows that its intensity depends on the composition of the gas mixture, flow, temperature, pressure and conductivity of the pipe material. The account features of the thermodynamic processes in underground vacuum pipelines made of composite materials will allow you to properly choose the installation location of the traps for water along the length of the pipeline. This will ensure timely and efficient removal of condensate and the continuity of working of system degasification in underground coal mines.
