Through the collection and arrangement of gas data in the West No.2 District of Weijiadi Coal Mine and the determination of gas parameters on site, this paper measures and uses the Langmuir equation to verify gas pressure in mining area. Based on comprehensive consideration of the coal body structure and coal seam gas parameters, according to coal and gas outburst sensitive indicators and critical values, the coal and gas outburst risk in 1# coal seam and 3# coal seam in Xi 2 mining area was predicted. The results show that No coal and gas outbursts are found in the West No.2 District.
