潘三矿顺层长钻孔掘进消突技术试验研究

Study of Outburst Elimination Technology of Long Hole Driving along Coal Seam in Pansan Coal Mine

针对淮南矿区潘三矿11-2煤层瓦斯含量高、瓦斯压力大、煤层透气性低,提出并实施了顺层长钻孔掘进消突技术,通过实施后的效果评价指标、瓦斯残存量等的考察,证实了顺层长钻孔的应用既消除了煤与瓦斯突出的危险,又加快了掘进进尺,是高瓦斯、低透气性突出煤层实现快速掘进的有效措施之一。

Direct to high gas content, high gas pressure, low coal seam permeability in Pansan Coal Mine, proposes and implementes an outburst elimination technology for long hole driving along coal seam, through the effect evaluation measure, such as the amount of gas remaining, confirms that the application of long holes not only can eliminate the risk of coal and gas outburst, but also can speed up the driving rate, which is one of the effective driving method for outburst seam.
