年第05期 摘要：针对目前无序采砂形成的许多采空区，造成地下空洞的特点，采用碎石填充（粒径5-16mm），再用袖阀管注水泥浆的方法进行处理。以期保证河道的畅通安全，减少对地质环境的破坏，防止河床变形，坡体滑动等灾害发生。结合现场试验，采用袖阀管注浆处理工艺处治河道采空区，经检验填充效果较好，能够较好地治理采空区病害。 关键词：河道采空区松香油;袖阀管注浆;处治效果
Abstract: in view of the present disordered mining goaf, resulting in the formation of many underground cavity, with the characteristics of gravel filling (size 5-16 mm) and then with sleeve valve pipe slurry method for processing. In order to ensure a smooth channel security, to reduce the destruction of geological environment, prevent bed deformation, slope sliding and disaster. Based on the field test, the sleeve valve pipe grouting process, the inspection will channel goaf filling effect is good, better able to control goaf diseases. 护理安全
Keywords: channel gob; Sleeve valve pipe grouting; Treatment effect.
