马尾沟矿井9#煤层瓦斯赋存特征研究

Masson ditch coal seam gas occurrence characteristics

众所周知,尽管国家对煤矿安全治理极其重视,并投入了大量的人力物力,但是,作为一个世界性难题,煤矿安全形势依然严峻。开采深度加深,开采条件就越来越复杂,煤层瓦斯更加难以治理,运用瓦斯地质理论,结合马尾沟矿井相关资料,研究分析了马尾沟矿井瓦斯赋存条件,探讨矿井地质构造特征,找出影响矿井瓦斯赋存的主控因素是煤层埋藏深度。建立煤层底板标高和煤层瓦斯含量的数学相关性关系,预测出深部煤层瓦斯赋存规律,从而对矿井安全生产以及煤层深部开采都有重要意义。

As everyone knows, although the state of the coal mine safety management attaches great importance to, and put a lot oi manpower and material resources, but, as a worldwide problem, coal mine safety situation is still grim. Mining depth, mining conditions are becoming more and more complex, coal-bed gas is more difficult to manage, use gas geology theory, combined with cauda equina ditch mine information, research and analysis of the Masson ditch mine gas occurrence conditions of coal mine, geological structure characteristics, find out the influ ence of mine gas in the main control factors of coal seam buried depth is. Establishment of coal seam gas content in coal seam floor elevation and mathematical correlation relationship, prediction of deep coal seam gas occurrence regularity, thus for the safe production in mine and coal seam in deep mining has important significance.
