管带机经过煤矿采空区的设计要点

Key Points of Design of Pipe and Belt Machine Passing Through Goaf of Coal Mine

近年来采空区的沉降问题给管带机的设计布置和安全稳定运行带来极大的困扰。本文通过分析某管带机输送项目的失败原因并结合新建项目,着重介绍了管带机在经过煤矿采空区时沉降柱的设计要点。

In recent years,the problem of subsidence in mined-out area has brought great trouble to the design arrangement and safe and stable operation of belt conveyor.Based on the analysis of the causes of past failure cases and the new projects,this paper mainly introduces the design and other key points of the settlement column when the belt conveyor passes through the goaf.
