Research on small scale structures in working face of coal mine

摘要: 通过实例研究,认为采煤工作面内有地质小构造(小断层或小褶皱)时,会导致两条回采巷道中线水平间距或者高程差发生变化。这种变化可以从两条巷道中线水平间距或者曲线图反映出来,曲线图上的拐点即为小构造出现的位置或尖灭点。由此预测小构造在工作面上的展布情况,并利用曲线下“凹”或上“凸”的特征,初步预测隐伏小构造的性质。

Abstract: The research is focused on small scale structures in working face through theory analyzing and practice studying.The small scale structures appeared in working face cause the level or altitude interval of two laneway midlines change.This change may be showed on graph of level or altitude interval.The graph inflexion is the small structure's starting or ending.Therefore,we can forecast the occurence and character of small scale structures in working face according to the graph's convex or concave.
