摘　　要：针对榆林地区特殊的地貌和煤层埋藏条件,在对风积沙和黄土性质分析的基础上,分别建立了风积沙和黄土覆盖下煤层开采模型,采用数值模拟计算,结合实际观测结果,对风积沙和黄土覆盖下煤层开采造成的地表移动进行了对比分析。Based on special terrain and coal bedding conditions and characteristics of Aeolian sand and loess, a numerical simulation model of mining coal under Aeolian sand loess was set up and rules comparison of surface movement induced by coal mining under Aeolian sand and loess was made with on-the-spot observation data.
