一、前言东梁矿一井是一九六六年新建矿井,一九六九年正式投产。我矿煤层地质构造复杂、断层多,在煤层底板深部有一石油层,因此煤层开采时,瓦斯变化很大,为超级瓦斯矿井,属极易自燃发火煤层。实践证明采区开采42～56天即发火.自从开采以来(由于投产初期未进行灌浆)因自燃发火留煤柱,封闭采区就达十三处之多,使国家煤炭资源受到了损失,井下安全生产受到影响。近几年来,我一井通风段革命职工在矿党
I. INTRODUCTION Dongliang Mine One Well was a new mine built in 1966 and formally put into operation in 1969. Due to the complicated geological structure and many faults, the coal seam of mine has a petroleum layer in the deep part of the coal seam floor. Therefore, when the coal seam is mined, the gas varies greatly and is a super gas mine. Practice has proved that the mining area 42 to 56 days that is angry. Since the mining (due to the initial production did not carry out grouting) due to spontaneous combustion remaining pillars, closed mining area reached as many as 13, the country suffered a loss of coal resources, underground Safety production is affected. In recent years, I have a ventilation section of revolutionary workers in the mine party
