This paper presents a new stationary device that can perform simultaneous measurements of air flow velocity and methane concentration in a mine heading (stationary methane anemometer). The test station is designed to use the instrument to test the effect of various parameters on the air-methane stream. The air velocities and methane concentrations were fed to the measuring area via an injector and recorded. The results present numerical simulations of flow phenomena that occurred during measurement experiments.
