摘要
通过对郑州矿区米村矿拟开采一_1煤突水危险性预测的分析,认为其大、中型边界断层对突水的影响较小,而小断层密集带的发育则是造成该矿今后突水的主要因素之一。根据米村矿开采二_1煤和相邻矿井王庄矿开采二_1煤和一_1煤揭露小断层情况,预测了可能造成米村矿一_1煤底板突水的小断层密集带的分布情况。
In the formerly researches on the effect factors of water burst, commonly believe that major or medium fault has controlling effect, while there are few researches on the important effect of water burst owing to minor fault concentrated belt. This paper believes that the development of minor fault concentrated belt is one of main reason of water burst. According to the distribution of minor fault concentrated belts in - 1 coal seam in Micun mine and adjacent 二 1 coal seam in Wangzhuang mine predicted possible water burst in these mines.
