Applications of Carbon Dioxide Cannon Blasting on the Problem of Triangular Flap Top in Coal Mine Handling Mechanized Mining Face

Abstract:

As mining process in the Mechanized mining face, making it easy come with flap top[1] along the the upward and downward entries. In this paper, through the use of carbon dioxide cannon, we do pre-split blasting experiment on triangular flap top in mechanized mining face, exploring an effective solution to a large area of goaf flap top suddenly breaking down, with the hurricane caused damage and fan-out of toxic and harmful gases, to achieve the purpose of production safety.
