重点探讨了煤矸石粒度分布的级配与压密性的关系问题，用不同颗粒级配煤矸石所作的压密和渗透对比试验的结果表明，影响天然煤矸石固结压密性的主要级配缺陷是细小颗粒含量比例过低，通过适当提高矸石中细小颗粒含量的级配改良，不但可以有效提高煤矸石的固结性，使其在较低的压密能量下取得较高的固结压密程度，并且能够使煤矸石的水稳性得到明显改善
The relationship between gradation and compactness of coal gangue particle size distribution was discussed emphatically. Comparing the compaction and infiltration comparative test with coal gangue with different particle size, it was found that the main gradation affecting compacted compaction of natural gangue The defect is that the proportion of fine particles is too low. By properly improving the gradation of the fine particles in the gangue, not only the consolidation of the coal gangue can be effectively improved, but also the higher consolidation pressure can be obtained under lower compacting energy Density, and can make the coal gangue water stability has been significantly improved
