摘 要:对东滩煤矿瓦斯异常涌出进行了分析,总结了在东滩煤矿井下易发生瓦斯涌出的地点和区域,提出了防范瓦斯异常涌出的措施。A low gaseous mine usually has low gas e mission quantity,however,when a coal face passes through some g eological zones,the gas concentration in return air may be oc casionally several times higher than the normal value or disallowed gas concentration be present,this is called abnormal gas emission.Abnormal gas e-mission is the key of gas control in lo w gaseous mines.Study shows that the geological zones where abnormal gas emission oc-curred are the abnormal gas zones.The type of abnormal gas e-mission includes gas burst,abnorma l gas blowout and concen-trated gas discharge in adjacent gob s.Abnormal gas emission is affected by both geology and mining technology.
