摘　　要：平朔安太堡露天煤矿排土场的排弃物料,由第四系黄土、第三系红粘土及石炭系、二迭系泥岩、砂泥岩、砂岩等构成,粒度不均,大小不一,这些物质构成了复垦土壤的母质。由于沉积时期的地质环境不同,而且剥采剖面厚达150余米,这样深厚岩土层的化学性质,矿物和元素组成差异较大。本文采用勘探钻孔资料与剥离岩土化学元素分析相结合的方法,分析了复垦土壤母质来源的地质背景、化学性状、元素组成,为合理、有效地重构高质量的复垦土壤和恢复植被提供科学依据。The discarded material of dump in Antaibao opencast coal mine of Pingshuo is made of quaternary period loess, tertiary peroid Red clay soil and mud stone, sandy mud stone, sandstone of carboniferous periods and Permian and so on,which constitute parent material of the reclaimed soil.Its granularity is asymmetry and its size is different.Because geology of the sediment epoch is different, and the stripped profile is deep to 150 m, the chemical character,mineral and element constitution of the deep rock and soil layer are also very different.The paper analyze the geologic background,chemical characteristic and element constitution of the parent material of reclaimed soil, thereby provide scientific basis for reasonably and effectively reconstructing the high quality reclaimed soil and restoring the vegetation.
