摘　　要：介绍ZZJ4000/28/68型复采综掘面临时支护系统,对综掘面巷道以及小窑巷采破坏区的顶板进行临时加强支护,介绍了小窑巷采破坏区的情况,临时支护系统的布置方式、技术参数以及功能。利用FLAC3D数值模拟软件以及井下实测压力相结合的方法,分析了临时支护系统对复采综掘面小窑巷采破坏区顶板的应力与位移的影响。结果表明:临时支护系统在小窑破坏区起到了护顶的作用。Introduce ZZJ4000/28/68 type when faced with complex mining： mechanized excavation support system for mechanized excavation and a small kiln lane roadway surface mining temporary roof damage zone reinforced support, introduced arrangement of temporary support systems, technical parameters and functions. The use of numerical simulation software FLAC3D measured downhole pressure and the method of combining the analysis of the impact of temporary support system for small kiln complex mining mechanized excavation roadway surface mining area of roof damage stress and displacement. The results showed that： temporary support system in a small kiln damaged area mainly from the nursing role.

关 键 词：复采综掘面 小窑巷采破坏区 临时支护 数值模拟 掘进效率
