Abstract

The invention provides a coal mine underground PM2.5 concentration simulation detecting system. The system comprises a mine environmental wind tunnel, a gas-solid steady flow ventilation system, a dust generating system, a temperature and humidity regulating system, a PM2.5 sensing system and a signal acquisition and analysis system based on Labview. The invention further provides a coal mine underground PM2.5 concentration simulation detecting method. The system simulates a mine dust generating environment and can completely and accurately reflect the overall real-time multi-space dust conditions in the coal mine underground, so that the problems that underground operation and experiments are difficult, the mine surface environment is difficult to simulate, in this way, mine dust measuring methods and dust control technologies are difficult to study deeply are solved, and the system and method have important significance for obtaining of the main features of underground PM2.5 and the novel methods and novel technologies for obtaining and measuring the PM2.5 by utilizing the new features.

Description

technical field [0001] The invention relates to the field of coal safety production detection, in particular to an underground coal mine PM2.5 concentration simulation detection system and a PM2.5 concentration simulation detection method. Background technique [0002] Coal mining enterprises will produce a lot of dust during the mining and excavation process. The dust concentration is sometimes high, and workers working in this environment will inevitably inhale a large amount of dust and affect their health, especially when inhaling fine particles, that is, PM2.5, it will cause pneumoconiosis; in addition, dust is explosive, which seriously threatens the safety of mine production. Therefore, effective measures must be taken to control the diffusion and flying of dust, so that the dust concentration in the working face and roadway can be reduced below the safe value, so as to ensure the environment and safe production conditions of underground operations. In terms of dust ...
