The Research on Geological Characteristics of the Dafosi Coal Mine Company 40110 Working Face

Article Preview

Abstract:

40110 working face is arranged as the third Mechanized sublevel caving mining face in the 401 east-wing area along the coal seam by Dafosi company of the Binchang Mining Group Corporation. According to the conclusion based on the research about Binchang area coal geology not only shows the roof and floor lithology, structure, hydrology, the gas, dust features and so on but also proposes mining roadway supporting schemes and putting them into practice. Practical application shows that roadway supporting schemes effectively control the two-sided displacement and relative movement of the roof and floor to ensure the daily production of coal mine.
