摘　　要：提出了矿山工程扰动土人工再造的概念、方法及特点,认为土壤人工再造即主要通过人为措施再造土壤,是矿山破坏土地的土壤恢复与重建。矿山工程扰动土人工再造的实质问题是土壤剖面的重新构造,并在较短的时间内形成适宜的土壤理化性状,改善再造土壤的环境质量。提出了土壤剖面再造的一般方法。同时,以山西平朔露天煤矿为例,分析了六大成土因素对于矿山工程扰动土这种特殊的人工土壤形成的影响,并分析了人为因素在其中所起的作用。最后建议在人工土纲下独立出一土类“工程扰动土类”,并根据扰动类型的不同,将工程扰动土分为工程堆垫土、工程下陷土。Concept, methods, characteristics and influential factors of artificial rebuilding of mining engineering disturbed soil with the connotation that artificial rebuilding of soil is to restore and reconstruct land destroyed in mining by artificial means. The essential problem with the restoration of mining engineering disturbed soil is to reconstruct soil profile, form proper soil physical and chemical properties in a very short period of time, and improve soil environment quality. A common method now in use in an open pit coal mine in Pingshuo, Shanxi is taken for example. Six soil forming factors are analyzed for how they influence soil forming of engineering disturbed soil in mining areas, and so artificial factors for their effects. And on such a basis, it is suggested that under the artificial soil order, a new soil type, ＂engineering disturbed soil＂, be established, and based types of disturbance, this type of soil be further divided into engineering heaped soil and engineering sinking soil.
