| 摘 要： | 介绍了我国沿空留巷整体浇注护巷带发展历程及其围岩控制技术理论基础,分析了整体浇注护巷带在绿色开采体系中的地位,指出存在的主要问题是机械化水平较低、充填系统相对复杂、成形效果与漏风的控制不是十分理想,对护巷带周围煤岩应力分布规律研究不够深入。在此基础上,提出应重视并加强护巷带不连续面结构分析,采用非等强支护技术发展沿空留巷整体浇注护巷带技术的建议。

| Abstract: | Introducing development procedure of whole-pouring roadway protective strip and theoretical base of surrounding rock control and analyzing status of whole-pouring roadway protective strip in green mining system,main problems were pointed out including lower mechanization level,complex stowing system and non ideal forming effect and air leakage control,and insufficient researching stress distribution of coal and rock body surrounding protective strip.On the basis of this,the suggestion was put forward that p... |
