摘　　要：分析了某矿3号煤综放工作面地质力学条件,采用工程类比法确定工作面顺槽围岩属Ⅲ类中等稳定类型,确定了工作面顺槽的基本支护方式。采用数值模拟方法,分析了205综放工作面顺槽受相邻206工作面和本工作面回采的二次采动影响后的顶底板、两帮移近量;顺槽锚杆、锚索和锚固范围内的岩层离层情况以及工作面顺槽围岩的屈服破坏情况;确定了受二次采用影响时工作面顺槽的合理支护方案,保证了安全高效生产。The geomechanics condition of No.3 fully mechanized face was studied.Engineering analogy was used to determine surrounding rocks of crossheading as type III stable.Therefore the basic supporting plan was selected for the crossheading.The numerical simulation was used to analyze roof-floor and two-side displacement of No.205 affected by No.206 working face after the second mining,to analyze the strata in the range of crossheading bolts,cables and anchors,and to analyze the yield failure of surrounding rocks.An appropriate supporting plan was selected in order to guarantee the safety and efficiency production.
