【摘要】：根据我国传统回撤工艺和新型回撤工艺的特点,通过对国内几种回撤工艺比较分析,并采用数值模拟方法对回撤空间在回撤时的巷道变形进行分析,确定采用预掘辅回撤通道、采煤机自开主回撤空间、单翼回撤工作面液压支架的回撤工艺;通过多年的摸索实践,创新加工了E型梁,形成了由"E型梁+普通支架+支架原有液压系统"组成的双通道单翼回撤技术,并在大宁煤矿试验成功。
[Abstract]:According to the characteristics of the traditional and new retreating processes in China, through the comparative analysis of several kinds of retreating processes in China, and the numerical simulation method, the roadway deformation of the retreating space is analyzed, and the pre-excavation auxiliary evacuation passage is determined. Self-opening of the main retreat space of the shearer, single wing retreating face hydraulic support retreating technology, through many years of exploration practice, innovative processing of E beam, The double channel single wing retreating technology composed of "the original hydraulic system of E beam support" was formed and successfully tested in Daning Coal Mine.
