Abstract:
In order to prevent and control the high concentration dust produced in the large mining height face, to ensure the health of the workers and safety of the working face, the 12511 large mining height face was researched in the Bulianta Coal Mine. The 12511 large mining face of eight meters in Bulianta Coal mine was researched by systematic thinking. This paper analyzed the main source and distribution of dust in high mining height face, and adopted a series of integrated control measures, including purified airflow, optimized internal and external spraying of coal machine, dust removed by negative pressure, dust captured by wet net, dust filtered by net, individual protection and so on. The dust concentration of large mining height working face is below the specified value of Safety Regulations in Coal Mine, which optimizes the working environment, improves the visibility of working face, and lays the foundation for the prevention of pneumoconiosis by taking these measures.
