斜切分层综放工作面瓦斯及自然发火防治技术

Gas and Spontaneous Combustion Prevention Technology in Oblique Cut Stratified Fully Mechanized Caving Face

通过对羊草煤业公司二矿斜切分层综放工作面瓦斯及煤层自然发火情况的分析,主要采取了本煤层边采边抽、高位钻孔抽放、采空区抽放、联合均压、氮气防火等综合防治技术,有效的防止了工作面瓦斯超限及自然发火现象,保证了安全生产。

Through the analysis of gas and coal seam spontaneous combustion situations at oblique cut stratified fully mechanized caving face in Yangcao Coal Company No. 2 Mine,comprehensive control technologies including draining while mining,high level drilling drainage,gob drainage,joint equalizing,nitrogen fire-proof are mainly obtained,which effectively prevents gas transfinite and spontaneous combustion phenomenon and ensures safety production.
