In order to solve the dust control problem caused by the increase of dust production in coal mine, based on the status quo and existing problems of the comprehensive dust control system of Donghuantuo mine, the comprehensive dust control concept of mine was sorted out, and the influence of dust removal fan, dust collector and wall duct on the dust concentration of working face was compared by using technical means such as field measurement, numerical simulation and experimental research. Further analyze the current situation of dust treatment of fully mechanized mining face, test the dust distribution in different locations and different processes, analyze the dust movement law and dust control system construction of comprehensive mining face, the dust migration law and dust control system construction of fully mechanized mining face, and the safety culture construction of mine comprehensive dust control system.
