在分析覆盖土、煤泥的理化性质基础上，进行了盆栽试验，通过观察测试植物生长状况及分析测试种植后不同处理的覆盖土性质，对煤泥作为覆盖土改良剂的可行性做了较系统的研究。结果表明，煤泥对覆盖土有一定的改良作用，主要表现在降低覆盖土的密度、增加田间持水量方面，这将有利于露天矿排土场复垦种植。 Based on the analysis of the physical and chemical properties of overburden and coal slime, pot experiments were carried out. By observing the growth status of the tested plants and analyzing the properties of the overlying soils after different treatments, the feasibility of using the slime as the soil improver was compared System research. The results show that the coal slime has a certain improvement effect on the covering soil, mainly in reducing the density of the covering soil and increasing the water holding capacity in the field, which will be conducive to the reclamation and planting of the dump.
