地下开采对带式输送机线路的影响

 近年来，地面长距离、大运量的带式输送机在煤矿中的应用日益普遍，煤矿井下开采活动将不可避免地对穿越其上方的带式输送机线路产生安全隐患，而目前带式输送机系统还没有适用的采动影响评价指标和方法。为此，本文就带式输送机的结构特点和开采沉陷的研究内容，分析了地下开采引起的地表变形对带式输送机的影响，总结了带式输送机线路的地表变形要求，并结合现场实例分析了某矿带式输送机线路过采空（动）区的安全性，为线路的安全设计及运行提供可靠的技术保障。

Influence on belt conveyor line by underground mining

Recently, ground long-distance, large capacity belt conveyor has been commonly used.Coal underground mining will cause hidden danger to the belt conveyor line inevitable which passing through the upper coal. However, belt conveyor has not a suitable evaluation index and method of mining influence presently. Therefore, according to the structural characteristics of belt conveyor and research contents of mining subsidence, this paper analyzes the influence of surface deformation caused by underground mining of belt conveyor, summarizes the surface deformation requirement of belt conveyor line and analyzes the safety of a certain mine belt conveyor pass by the mine-out area based on the field example which supplies the reliable technology guarantee for the safe design and operation of line.
