摘要
通过矸石颗粒组成筛分试验、物理参数和化学成分室内试验，取得了煤矸石颗粒级配组成，不均匀系数很好，起骨架作用的ＳｉＯ２含量较高，也含有少数易风化、潮解的成分，压缩试验获得了干燥和饱和状态下，矸石地基的空隙比、压缩系数、压缩模量和压力之间的变化关系，并定量计算出矸石地基的沉缩量。
The size distribution of coal gangue was obtained by screening test and indoor test of physical parameters and chemical compositions. The unevenness factor is proved to be very good. The content of SiO 2, which plays the role of skeleton,is high.There are a few compositions liable to weathering and slaking.The relationship between void ratio, compressibility coefficient, compression modulus and pressure of gangue foundation have been obtained through compression test under the dry and saturated state. The amount of gangue foundation subsidence has been quantitatively calculated.
