摘要
通过注水压力、围压、浸泡时间对煤体含水率的试验研究,得出结论:煤体含水率随水压的增加而增大;但含水率随水压的增加呈非线性关系。围压与水压的影响相反。在水压相同的情况下,含水率随围压的增加呈非线性减少,但是这一规律与煤体在该围压下所处的变形阶段相关。同时,含水率随浸泡时间的延长,其增长趋势逐渐变的缓慢。
Through the experimental study on affusion stress,confining pressures and immersion times infusion in coal seam it is concluded that： the water content rises with increasing allusion stress; but followsa non-linear relationship.The confining pressure impact is opposite from the allusion stress impact, in the same water pressure, water content increase with the confining pressure by a non-linear curve, but the law is related to the deformation stage of coal mass.At the same time the water content rises with water immersion time, by slow-down trend.
