煤岩渗透实验方法分析及改进

Analysis and Improvement on the Permeability Experiment of Coal-Rock

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。

The factors which lead to errors in the experiment of studying the change law of permeability of coal - rock were analyzed. According to the theoretical analysis on the procedure of experiment and data processing, it was considered that irrational operation in experiment and irrational choose of parameters in data processing are two important reasons for the errors in determining the permeability of coal - rock. These two factors leading to errors were analyzed, and some corresponding improvements and suggestions to decease the affection of the two factors were proposed. It has important significance for the permeability research experiment.
