水压、围压、浸泡时间对煤体含水率影响的试验研究

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.

Experimental Study on the Infuluence of affusion Stress Confining Pressures and Immersion Times on the Water Content in Coal Body

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 affusion stress;but followsa non-linear relationship.The confining pressure impact is opposite from the affusion 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...
