在研究煤岩渗透率变化规律的实验中,存在很多引起误差的因素。通过对煤岩渗透实验过程及数据处理过程的理论分析,指出实验过程中的不合理操作和数据处理过程中选用参数的不合理性是导致煤岩渗透率测定出现误差的主要因素,并对这两种因素造成实验误差的原因进行了分析论证。针对这两种因素,提出了相应的改进措施及建议。对煤岩渗透率相关规律研究的实验有着重要的实际意义。
In the experiment of studying the variation law of coal permeability, there are many factors that cause the error. Through the theoretical analysis of the experimental process of coal and rock infiltration and the data processing, it is pointed out that the unreasonable operation during the experiment and the unreasonableness of the parameters used in the data processing are the main factors leading to the error of coal and rock permeability. The causes of experiment error caused by two kinds of factors are analyzed and demonstrated. In view of these two factors, the corresponding improvement measures and suggestions are put forward. Experiments on the correlation of coal and rock permeability have important practical significance.
