摘要

通过对煤矸石料的室内动强度试验，得出了不同初始固结比下煤矸石的动强度以及动强度包线，初步研究了煤矸石的动力特性，并对煤矸石的动强度与破坏时其振动周数之间的关系曲线进行了拟合，给出了其数学表达式。根据试验所得动强度包线的特征，分析了煤矸石动强度参数的变化规律，为煤矸石在实际工程中的应用提供参考。

Abstract

A series of laboratory tests about dynamic strength of gangue were performed

which reveals the influences of different initial consolidation ratios on dynamic strength and dynamic strength envelope. Then the dynamic characteristics and dynamic strength envelope characteristics of gangue are preliminary obtained. So do its curve fitting between dynamic strength and vibration number when failure and its mathematical expression. Based on Mohr strength envelope characteristics

the dynamic strength parameter of gangue is analyzed. All these provide reference for engineering.
