我国适合露天开采的煤田，主要分布在西部及西北部的黄土高原地区。黄土基底构筑物在加载过程中，曾出现过某些惨痛的工程教训。基于黄土基底排土场形成后黄土底工程性质演化规律及失稳机制分析，提出其边坡稳定的研究方法，对黄土高原地区煤炭资源开发建设具有重要的理论与实际意义。
China is suitable for open-pit coal fields, mainly in the western and northwestern Loess Plateau. Loess base structures in the loading process, there have been some painful engineering lessons. Based on the analysis of the evolution law and instability mechanism of loess bottom after the formation of the loess foundation dump, the research method of slope stability is put forward, which has important theoretical and practical significance for the development and construction of coal resources in the Loess Plateau.
