底板钻场瓦斯抽放

Gas Drainage of Floor Drilling Field

介绍杏花矿在回采西二采区28#右三采煤工作面时,采用施工煤层底板钻场抽放瓦斯,有效地控制了28#以下煤层瓦斯向上涌出,为今后综合治理高瓦斯涌出采煤工作面提供了依据。

The paper introduced the gas drainage by constructing coal seam floor drilling foield while actual mining at righ 3 coal mining face, west No. 2 mining area,28^# seam in Xinhua Coal Mine, the method efficietly controlled the gas outburst from under 28^# seam to top and provided a basis for futunal comprehensive controlling gas outbust face.
