In order to analyze the present situation of dust hazards in the process of mining in the open-pit quarry and solve the problem of dust pollution, according to the production process characteristics of the open-pit quarry, the characteristics and dust properties of the open-pit quarry were analyzed and studied, and the rules of dust production in the open-pit quarry were obtained. Based on the basis of the research on the law of producing dust and dust properties, in view of the blasting operation, drilling, crushing screening operation and blanking operation and so on various production technology, respectively, puts forward the demolition operations fog gun dust suppression technology, drilling rig drilling dust removal technology, dump truck, crusher airtight spray dust spray dust suppression technology, screening airtight smoke dust purification technology and scale blanking dust removal technology such as prevention and control technology, through the technical mechanism of dust and dust efficiency of experimental research, formed a set of suitable for quarry dust control technology parameters, through the production process in the open air quarry in practical applications, It realizes the dust control in the whole process from mining to production of finished products in the open-pit quarry, greatly reduces the dust concentration in the production process of the open-pit quarry, and the comprehensive dust removal efficiency reaches more than 85%, which provides the basic basis for dust control in the open-pit quarry.
