摘要
为深入分析煤矿综采工作面的矿压显现与顶板蠕变特征,选取山西省某煤矿作为研究背景,基于地质资料对矿山煤岩取样,开展室内力学实验。而后基于实验测定试样基本力学参数,并绘制试样蠕变曲线。结果表明,该煤矿试样抗压强度随围压增加而提升,蠕变现象随应力及时间变化显著。
In order to in-depth analysis of the mine pressure manifestation and roof creep characteristics of the fully mechanized coal mining face,a coal mine in Shanxi Province was selected as the research background.Based on geological data,coal rock samples were taken from the mine and indoor mechanical experiments were conducted.Then,based on experimental measurements,the basic mechanical parameters of the sample are determined,and the creep curve of the sample is plotted.The results show that the compressive strength of the coal mine sample increases with the increase of confining pressure,and the creep phenomenon changes significantly with stress and time.
