摘　　要：断层识别是巷道掘进的关键基础工作,不仅是获取可靠地质资料的基础,也是矿井安全生产的基础.为确定断层性质,根据断层出现的预兆,并结合现场实例,研究了断层的各种识别方法.研究表明,断层识别总体上可归纳为直接法和间接法两大类,由于地质条件的复杂多样性,单一的方法很难识别断层性质,判断断层是多种方法的综合.另外,处理断层可采取改变巷道的掘进方向和掘进坡度,同时,巷道过断层还需要根据现场实际情况,加强巷道支护.Fauh recognition is a basic work of driving roadway in coal mine, it not only is a base to obtain reliable geology data, and also is basis for safety production of coal mine. In order to determine fault properties, based on the field example and the appearance of fault, kinds of fault recognition are studied. Fault recognizing is concluded to direct method and indirect method in general, and the judgment of fault is comprehensive of various methods, but it is difficult to recognize fault through single method because of complex diversity of geological conditions. Fault treatment changes the direction and slope of excavation roadway, and strengthen roadway support based on actual operating condition.
