摘　　要：为解决公乌素煤业驻新疆221团煤矿松软破碎煤层巷道支护的问题,对其围岩矿压特征进行分析谈讨,采用普氏地压理论和悬吊理论初步确定其支护方案,并采用FLAC3D软件结合具体的地质条件优选支护参数,巷道掘进期间进行围岩位移监测,结果表明,两帮移近量小于90mm,顶底板移近量小于70mm,取得了良好的围岩效果良好。为矿井相似地质条件下煤巷的支护提供参考和借鉴。In In order to solve the problem of roadway support for the soft and broken coal seam of Gongwusu Coal Industry in Xinjiang 221 Regiment Coal Mine,the pressure characteristics of its surrounding rocks were analyzed and discussed,and its support plan was initially determined using Platts ground pressure theory and suspension theory.The FLAC3D software was used in combination with specific geological conditions to optimize the support parameters.The surrounding rock displacement monitoring was performed during the roadway excavation.The results showed that the approach of the two sides was less than 90mm and the approach of the top and bottom floors was less than 70mm..It provides reference and reference for coal mine roadway support under similar geological conditions.
