摘要
对焦西矿四一采区复杂的地质采矿条件及其地面受护建筑物的结构、质量和抗变形能力进行了深入研究，提出了条采方案，得出最佳方案为条带煤柱宽度３３ｍｍ，采出条带宽度东部２０～４５ｍ，西部８～４０ｍ，取得了显著的经济效益和社会效益．
Investigation on the complicated geological and mining conditions in certain area of Jiaoxi coal mine and the capacity of resistance to deformation of buildings which are to be protected in the area have performed. Optimum mining programme has been put forward and noticeable economic and social benifit are obtained.
