摘　　要：以赤峪矿C0202工作面的实际地质条件为背景,针对该工作面沿空留巷方式提出了原位沿空留巷、半原位沿空留巷和破底半原位沿空留巷3种留巷方式。应用UDEC数值模拟软件对上述3种留巷方式条件下巷道周围主应力、位移、塑性破坏等情况进行了数值模拟分析,并进行了可行性对比。With the actual geological condition of Chiyu mine C0202 working face as the background, aiming at the roadway retained for next sublevel, original position, half original position and breaking bottom half original position are put forward. UDEC numerical simulation software was used to analyze the main stress, displacement and plastic damage of the surrounding roadway and make contrast about feasibility.
