摘　　要：为研究巨厚黄土层采动地表移动规律,文章以霍州煤电辛置矿为工程研究背景,采用理论分析与现场实测相结合的研究方法,求取了地表移动变形极值,分析地表沉陷的基本特征,确定了地表沉陷的角量参数和概率积分预计参数,为相似地质采矿条件开采提供技术指导。In order to study the law of surface movement caused by mining in huge thick loess stratum, taking Huozhou Coal Power Xinzhi Mine as an engineering research background, the extreme value of surface movement and deformation is obtained by combining theoretical analysis with field measurement, the basic characteristics of surface subsidence are analyzed, and the angular parameters and probabilistic integral prediction parameters of surface subsidence are determined, which provide technical guidance for mining under similar geological and mining conditions.
