浅析“静压水冲扩孔预抽瓦斯”防突技术
nalysis of “pre-pumping static water will reaming gas” against Outburst
南桐煤矿保护层巷道掘进中存在严重的煤与瓦斯突出危险,瓦斯又较难抽放,且在实施本层钻孔时还多次发生突出的情况下,采用“静压水冲扩孔预抽瓦斯”防突技术,经过近2 a的实践表明,该技术既经济又利于瓦斯抽放,能有效防止煤与瓦斯突出事故。
Nantong Coal Mine Tunneling protective layer there were serious dangers of coal and gas outburst and gas also difficult to drainage, and in the implementation of this layer of drilling Shihai case highlighted on many occasions, a \\\"static pressure of water will pre-reaming pumping gas \\\"against Outburst, after nearly 2 a practice has shown that the technique is economical and beneficial to gas drainage, can effectively prevent coal and gas outburst acciden
