摘要
结合工程实际,综合运用巷道支护理论,提出采用可缩性U型钢棚支护工艺进行采空区段支护,并通过矿压观测技术对支护方案的应用效果进行监测。结果表明,巷道顶底板与巷道两帮位移量均处于安全允许范围内,证明了该方案的可行性,从而为矿井后期相似工程的处理提供了有效的数据支撑。
Combined with the engineering practice and the comprehensive application of roadway support theory,this paper proposed to use the collapsible U-shaped steel frame support technology to support the goaf section and monitored the application effect of the support scheme through the mining pressure observation technology.The results showed that the displacement of roof,floor and two sides of roadway were within the safe allowable range,which proved the feasibility of the scheme and provided effective data support for the treatment of similar projects in the late stage of the mine.
