马家沟矿0521工作面卸压带的测定研究

THE MEASUREMENT RESEARCH ABOUT THE LENGTH OF DISTRESSED ZONE IN MAJIAGOU 0521

摘要: 在煤与瓦斯突出矿井,卸压带大小与煤和瓦斯突出存在直接有关。本文通过实验测定出马家沟矿0521工作面的原始瓦斯含量及残余瓦斯含量,结合现场统计的数据,进行理论分析与计算,计算出马家沟矿0521掘进工作面前方的卸压带长度为6m,为防治煤与瓦斯突出提供了有力的依据。

Abstract: In the coal and gas outburst well, the length of distressed zone is relate of outburst According to the original and remained gas content; combining the spot data, the length of distressed zone in 0521 is worked out which is 6m. It can provide powerful proof for preventing the outburst of gas.
