急倾斜高瓦斯厚煤层综放工作面瓦斯运移规律研究
|
摘要
以大黄山矿+735工作面为研究对象,针对其急倾斜厚煤层的特点,对采煤面和上隅角进行布点实测。依据实测结果分别分析了采煤面瓦斯浓度在倾向、走向、垂直底板3个方向的变化规律;不同位置放煤时工作面瓦斯浓度的空间分布;不同生产工序和不同放煤位置对上隅角瓦斯浓度的影响。最终得出急倾斜高瓦斯厚煤层综放工作面的瓦斯运移规律。
Takes + 735 working face in Dahuangshan coal mine as the research object, according to the characteristics of the steep thick coal seam, the coal mining face and the measured angle is putting on.Based on the measured results, the coal face gas concentration changing rule were analyzed in the three directions of tendency, direction, vertical bottom; the spatial distribution of gas concentration in working face were analyzed when caving top-coal in different position; the effect of gas concentration in upper corner were analyzed in different production processes and when caving top-coal in different position.Finally, the gas migration rule is studied in fully mechanized working face with the characteristics of the steep thick coal seam.
