乌鲁木齐矿区属急倾斜煤层群,含可采煤层33层,分四个煤组,组间距50—100米,组内煤层间距较小.煤层累计厚达112米,其中特厚、中厚占总厚的61%,第四纪覆盖较浅,除一些薄层外皆遭到小窑的破坏,采空区地面塌陷严重,加之降水少,自然淤合能力很低,所以这里的矿井普遍存在严重的地面漏风. Urumqi mining area is a group of steep coal seams, with 33 layers of coal mining, sub-four coal group, the group spacing of 50-100 meters, the group within the coal seam spacing is small.The total thickness of the coal seam 112 meters, of which thick, medium thickness The total thickness of 61%, the Quaternary relatively shallow cover, except for some thin layer are outside the small kiln damage, gob of ground collapse serious, combined with less precipitation, natural silting ability is very low, so the mine is widespread Serious ground leakage.
