Mine Dust Concentration Measurement Method Based on Model of Dust Concentration and Humidity

摘要

According to the coal mine underground work place humidity changes affect the measurement precision of dust concentration, improper spray cause coal with the water loss and wastes a lot of water resources, the paper put forward a correction factor of dust concentration based on the relative humidity, establish the relation model of concentration and humidity. The test results show that: the dust concentration correction factor and relationship model of concentration and humidity are effective and scientific, it has better practicability to solve the problem of underground coal mine.
