摘　　要：在急倾斜煤层的综放开采过程中,巷道变形与失稳对安全生产影响极为严重。乌鲁木齐矿区地质条件极为复杂,主采煤层均为急倾斜特厚煤层,地压活动强烈,煤岩接触带巷道局部变形、冒顶与底鼓严重,且有局部垮塌现象。通过对大洪沟矿+555B1～B6巷道围岩松动范围进行监测分析与评价,其巷道总体稳定性较好,因其处于煤带转折附近,地质构造复杂,煤层错位、松散、破碎。During the process of full-mechanical mining of steep coal seam, the roadway＇s deformation and instability impact on the production safety is serious. The geological conditions of mining in Urumqi is complicated, the main coal seam is steep and thick while the ground pressure activivity strong. There is serious deformation, cave and floor heave serious, and even partial collapse. By ＋555 B1 - B6 road- way surrounding rock loose scope monitoring, analysis and evaluation of Dahonggou coal mine, the basis for follow-up safety mining is provided.
