摘　　要：本文利用条带开采地表沉陷预计的层状介质理论。在敏感性分析的基础上，给出了条带开采地表沉陷预计的主控因素为：煤层附近几十米岩层的分层厚度和分层弹性模量、采出条带宽度和保留条带宽度，当采区尺寸较小时。Using bedded medium theory for estimating the surface subsidence in partial extraction. this paper given the major factors of surface subsidence in partial extraction, based on the sensitivity analysis. such as the slice height within several tens m near coal seam and its slice elastic modulus. the width of mined and retained strips, and the length and width of mining area when the size of mining area is small.
