摘要
利用四极探针法测定电阻率的原理搭建了水在煤体中渗吸特征的实验平台,开展了水在长焰煤、焦煤、瘦煤和无烟煤4种不同变质程度煤样中的渗吸特征实验,结果发现在煤样高度方向上,随着渗吸时间的延长,渗吸高度逐渐增加,但增加的速度逐渐减慢,渗吸高度和渗吸时间之间符合幂函数关系。
Based on the principle of measuring resistivity by quadrupole probe method,the experimental platform of water imbibition characteristics in coal was built,and the experiments of water imbibition characteristics in long flame coal,coking coal,lean coal and anthracite coal samples with four different metamorphic degrees were carried out.The results show that the imbibition height gradually increased with the extension of imbibition time,but the increasing speed gradually slowed down,the relationship between infiltration height and infiltration time is power function.
