小褶曲在综采工作面隐伏断层预测中的应用

Forecast of faults concealed in fully mechanized coal mining face by use of small fold

在综采工作面的准备和回采过程中,小褶曲是可能存在隐伏断层的征兆。利用空间解析几何方法,对小型褶曲构造进行观测研究,认为对煤层产状的变化进行观测,可以较早地发现隐伏断层影响范围内的产状异常,较准确地预测采掘前方可能存在的隐伏断层,使井下钻探或物探探测断层的工作得以有目的有重点的进行,并缩短了探测距离。经在绿水洞煤矿实际应用,这一预测方法得到了初步验证。

During the preparative and mining process of fully mechanized coal mining face, meeting small fold is a premonitor that there may be concealed fault around the face. The paper provides a way to measure and study small fold, and furthermore to forecast concealed fault by use of space analytic geometry. The method has been testified in practice.
