摘要吸水是导致深部软岩变形乃至破坏的主要原因之一。通过对益新煤矿深部软岩样品进行Ｘ射线衍射实验、扫描电镜实验及无压吸水实验，综合分析研究区岩石试样的吸水特性及其影响因素。研究结果表明：3种岩性岩石样品的吸水过程趋势大体一致，均为减速吸水过程，可用负指数函数进行拟合，但各自吸水能力存在一定差异，吸水能力强弱排序为泥岩(0.74%)＞粉砂岩(0.56%)＞中砂岩(0.27%)。黏土矿物含量和分形维数对吸水能力影响显著，呈现良好的正相关关系；不同矿物成分对吸水能力的影响存在明显的差异，伊利石对吸水能力有明显的促进作用，石英和高岭石则对吸水能力有抑制作用。

Abstract：Water absorption is one of the most important cause of deep soft rock deformation and failure. In this paper，X-ray diffraction，scanning electron microscopy and test of water-absorbing without pressure were carried out on deep soft rock samples in the Yixin coal mine. Water absorption characteristics and its influencing factors of rock samples in the study area are comprehensively analyzed. Results have shown that the patterns of the water absorption trends of the three types of rocks were all characterized by a similar kind of dynamic process with decreasing water absorption rate which could be well fitted by a negative exponential function. However，significant differences were found in water absorption ability among the three types of rock samples which could be sorted in an order of mudstone(0.74%)＞siltstone(0.56%)＞medium sandstone(0.27%). The content of clay minerals and fractal dimension have a significant effect on water absorption capacity，which all show a good positive correlation. There are obvious differences in the effect of different mineral compositions on the water absorption capacity. Illite can obviously promote the water absorption capacity，while quartz and kaolinite can inhibit the water absorption capacity.
