多煤层小断层特征差异性分析

THE ANALYSES OF DIFFENCE ON THE CHARACTERISTLCS OF SMALL FAULTS IN COAL-BEDS

以多煤层区采掘资料为依据，通过对不同煤层间小断层特征的比较研究，论证了煤岩层岩性、厚度及组合在煤层小断层发育中的作用，提出了“岩层力学性质”的概念，对多煤层开采矿井中小断层的研究和预测有一定的指导意义。

This paper,based on the data obtained from mining work of multiseam districts,through the comparis and study of the characteristics of small faults between various coal-beds,analysise the produce effect on lithological characters,thicknesses and sets on the development of small faults between coal seams,puts for ward a concept of “The mechanical properties of sedimentary rocks”,it's an important significance in gurding mutti-seam mining and research and prediction of small faults in colliery.
