所谓断失翼煤层的寻找,是指地质人员在井下利用各种手段来确定断层的性质和断距,从而为巷道掘进指明前进方向的工作。当煤矿巷道掘进遇到落差大于巷道高度的断层时,就会出现“断死”的情况,即原有煤层不能出现在视线内,需要地质人员利用各种方法判断出断层另一盘的煤层。为了正确判断断失翼煤层的位置,合理确定过断层找煤巷道的方向和坡度,此项工作必须准确合理的进行。本文就介绍一下煤矿生产中常见的寻找断失翼的方法。
The so-called fault-finding coal seam is the geological staff in the use of various tools to determine the nature of the fault and the fault line, so as to indicate the direction of roadway heading work. When the coal mine tunneling encountered a drop greater than the height of the fault roadway, there will be “broken ” situation, that the original coal seam can not appear in the line of sight, the need for geological personnel to use a variety of methods to determine the fault of another plate Seam. In order to correctly determine the location of the faulty wing coal seam and reasonably determine the direction and slope of the coal tunnel crossing the fault, this work must be carried out accurately and reasonably. This article describes a common method of finding fault wings in coal mine production.
