摘要
针对低透气性薄煤层的特殊性,采取了工作面风煤钻长孔释放、上隅角抽放、仰角钻场穿层钻孔抽放、高位钻场水平钻孔抽放等措施,消除煤与瓦斯的压力,有效遏制了煤与瓦斯的突出,确保了安全生产。
Aimed at the particularity of thin coal seams with low .of a long hole drilling, upper corner drainage, elevation drilling permeability, takes the measures drainage, level drilling drainage at high position to eliminate coal and gas pressure, effectively prevent coal and gas outburst to ensure safe production.
