摘要
新集三矿井田由于受推覆—逆冲断层的影响,总体上煤层陡立,倾角在60～80°以上,且1煤底板突水威胁严重。该文基于以上因素,对1煤层开采的充水因素、隔水层阻隔水性、突水危险性及其与急倾斜因素的关系进行研究分析,为1煤底板防治水措施提供依据。
Affected by overthrust fault in The third coal mine of Xinji,Most parts of this coal seam are deep inclined,and the obliquity is above 60°～800.There is great water inrush possibility of 1# coal floor.Based on this analysis,the article makes an analysis on the hydrogeology conditions of 1# coal seam,waterfilling factors and watertightness,estimates the relationship of the harm of water bursting and deep incline factor,and provides evidence for the measure of preventing and curing the water-harm of mining.
