Abstract: On the basis of previous research on the theory of gas displacement technology, this paper carried out the industrial
test of gas displacement in the coal mining face of coal and gas outburst mine, and collected relevant parameters such as extraction
flow, extraction concentration for comparative analysis.

Key words: gas injection displacement; gas drainage; gas control; coal mining face
