随着煤矿机械化的发展,采煤机组的逐步普遍采用,要求矿井地质工作者能预测出井田各区段小型断层的分布情况,以便为机械化工作面预先圈定出小断层稀少的、能保证采掘机械顺利向前推进的区段。新庄孜矿多年来预测井田断层的实践表明,落差大于30米者划为大型断层,5～30米之间者划为中型断层,小于5米者划为小断层比较合适。这一划分界限,应随采掘技术的
With the development of mechanization of coal mines, the gradually universal adoption of coal-mining units requires mine geologists to predict the distribution of small faults in various sections of the minefield in order to predetermine for the mechanized face a small fault of a small fault preliminarily and ensure the smoothness of the mining machinery Drive forward. The practice of the Xinzhuangzi Mine that predicted the minefield fault over the years shows that those with a drop of more than 30 meters are classified as large faults and those between 5 and 30 meters are classified as medium faults. Small faults less than 5 meters are more suitable for small faults. This division of boundaries should be mining technology
