Abstract: Abstract:According to the occurrence and mining conditions of 19 # coal seam of Baliancheng , the coal gas sources are analyzed in the process of mining ; according to the characteristics of the gas distribution, the air volume has been determined, and gas disaster has been effectively prevented through to take the technology—play elevation drilling to drainage gas and Set up the Patio in the roadway and buried pipes in the gob—in coal face 21906. In the meantime, the upper and lower tail lanes are applied with the measures such as tail lane filling and pre-split blasting of the roof which can prevent gas accumulation.The accumulated experience of design and construction, for the mine even for the entire Huichun Coal Mining area has a good effect of reference and guidance.

Key words: Keywords:gas control, gob, buried pipe, tail lane, pre-split blasting
