多年以来,断层煤一直影响着煤矿的安全和开采,翻阅地质图文件,常用断层走向来表达断层的位置,针对于具有特殊性的煤矿生产,在掌握断层走向的同时还要对断煤的交线方向重点把握。在一般情况下,断层的倾角较小,煤层的倾角较大,所以断层煤和断层的走向往往存在一个夹角。可通过求此夹角来正确判断断层附近的煤层位置,以常见的正断层为例,通过煤层的倾角和断层的走向来推到导断层走向和断煤交线的公式,利用实际开采中的实例正式推导出的公式具有普遍性。
Over the years, the fault coal has been affecting the safety and mining of coal mines, read the geological map files, the fault is often used to express the location of the fault, for a particular coal mine production, in the grasp of the fault trend but also on the coal off Focus on the direction of the line. Under normal circumstances, the dip of the fault is small and the dip of the coal seam is relatively large, so there is often an angle between the fault coal and the fault. By judging the included angle, the position of coal seam near the fault can be correctly judged. Taking the normal normal fault as an example, the formula of the strike of the fault and the coal cut is deduced according to the dip of the coal seam and the strike of the fault. The formally derived formula is universal.
