摘　　要：介绍了一种解决煤矿综放工作面运输巷端头顶煤回收的新型支架。通过对综放面端头和运输巷矿压显现规律、顶煤运移规律研究,研制出与现有工作面设备配套的工作面运输巷端头放顶煤支架,不仅解决了工作面运输巷端头及超前段顶板机械化支护问题,更重要的是解决了工作面运输巷端头顶部煤炭的回收难题,消除了丢失顶煤自然发火的隐患,有利于安全生产并具有巨大的经济和社会效益。A new kind of hydraulic support for reclaiming coal at ends of transportation tunnels on fully-mechanized caving faces is introduced.By studying strata pressure laws of ends of fully-mechanized caving faces and transportation tunnels as well as movement laws of top coal,a sublevel caving support used at ends of transportation tunnels fitted with present equipments on fully-mechanized caving faces is developed.The support not only reclaims the top coal at ends of transportation tunnels,but reduces the hidden hazard due to spontaneous combustion of lost top coal,which is of benefit to safe production and has great economic and social benefits.
