为了研究煤层渗透失稳机理和检验已建立的煤层渗透失稳判别式的合理性,研制了试验装置,并进行了不同煤样室直径和不同煤样压实压力的对比试验。试验结果验证了判别式的合理性。
In order to study the mechanism of coal seam seepage instability and test the established judgments of permeability instability, a test device was developed and a comparative test of different coal sample chamber diameters and different coal sample compaction pressures was carried out. The test results verify the rationality of discriminant.
