泵送支柱技术在工作面过空巷中的应用分析

Application analysis of pumping pillar technology in workingface passing through empty roadway

在回采工作面开挖作业中,工作面过空巷是最常出现的一种现象,如果不加以科学处理,在施工期间很容易因压力的加剧而导致顶板出现破裂等问题,进而威胁作业安全。泵送支柱技术是近几年应用到回采工作面中的新型巷道支护技术,其可增大作业中支撑面的面积,加强作业面抗压能力,增大结构强度,进而维护回采工作面的作业安全。以实际施工案例为基准,对泵送支柱技术在工作面过空巷中的应用进行分析。

In the excavation of the working face,it is the most common phenomenon that the working face passes through the empty lane.If it is not dealt with scientifically,it is easy to crack the roof due to the aggravation of the pressure during the construction,thus threatening the safety of the operation.Pumping pillar technology is a new type of roadway support technology applied to the working face in recent years.It can increase the area of the supporting surface,strengthen the compressive capacity of the working face,increase the structural strength,and then maintain the working safety of the working face.Based on the actual construction case,this paper analyzes the application of pumping pillar technology in the working face passing through the empty lane.
