| description | The invention relates to a method for testing the service performance of a foam dust fall device for an underground coal mine and a tunnel, and belongs to the technical field of coal mine and tunnel construction safety. A flexible air duct with a proper diameter is selected as a simulated roadway or tunnel, simulation of dust falling operation under the application scene is realized through cooperation of a ventilator, the flexible air duct, a dust release pipe and a foam dust falling device, dust in air flow is collected at each measuring point of a sampling section, the concentration of the dust is calculated, and the simulation result is obtained. And the service performance index of the foam dust suppression device under the working condition is obtained. According to the invention, the problem of testing the service performance adaptability of the foam dust settling device under the conditions of different operation sections and air supply amounts is solved, and important technical support is provided fo |
