摘　　要：条带式开采是解放"三下"压煤的一种有效的开采技术,是我国建(构)筑物下采煤最为广泛的一种绿色开采方法。针对不同地理区域条件进行合理的建筑物下及村庄下压煤开采,可以实现矿井煤炭资源的合理高效回收,改善大部分矿井资源逐渐枯竭和接续紧张的局面。以小屯矿佛店村下压煤的实际条件为基础,根据条带式开采现有的相关理论,运用现场实测数据分析和经验公式预算的方法,粗选不同采留宽度的开采方案,借鉴条带开采数值模拟和实例,建立并运行各个开采方案的媒柱稳定性数值模型,对条带开采留设煤柱稳定性进行数值模拟分析并选出最优方案。The strip-partial mining method is a useful mining technology for the ' three-under mine',this method is widely used in green mining.Reasonable mining coal under buildings and villages according to different geological conditions can realize the reasonable and high-efficient recovery of coal resources,and improve the status of coal resources exhaustion and the lack of future substitute reserves.Based on the geological mining condition under Fodian villages at Xiaotun Coal Mine,according to the existing theories of the strip-partial mining,method of analyzing the site actual measurements and calculating the result by empirical formula were used to roughly choose mining schemes with different width of mining and pillar.According to numerical model and examples of strip-partial mining,numerical models of kinds of mining schemes were built and run.Numerical simulation analysis was carried out for the coal pillar stability of strip-partial mining,and the optical plan was determined.
