新密煤田煤与瓦斯突出的构造控制作用
|
摘要
为了解新密煤矿构造煤对煤与瓦斯突出的影响,运用板块构造理论和区域地质演化理论,研究了新密煤田构造煤和瓦斯赋存特征,结果表明:新密煤田受秦岭造山带隆起的强烈推挤作用和裂陷活动控制,突出矿井、高瓦斯矿井和低瓦斯矿井呈北西向条带状展布,瓦斯灾害的严重程度由南向北依次降低;南侧的告成、大平和超化矿井为煤与瓦斯突出矿井,中部的裴沟矿为高瓦斯矿井,北侧的芦沟、米村和张沟矿为低瓦斯矿井。
In order to understand the mine structure coal influenced to the coal and gas outburst,with the plate tectonics theory and the local geological evolution theory,the paper studied the structure coal and gas deposit features of Xinmi Coalfield.The results showed that Xinmi Coalfield was seriously pushed and pressed by the rise of Qinling orogenetic zone and controlled by the cracking and subsidence.The outburst mine,high gassy mine and low gassy mine were layout as a strip direction to northwest.The serious degree of the gas disaster would be reduced from south to north.The south mines as Gaocheng Mine,Daping Mine and Chaohua Mine would be coal and gas outburst mines.Peigou Mine in the central would be a high gassy mine.The north mines as Lugou Mine,Micun Mine and Zhanggou Mine would be low gassy mines.
