矿井工业场地管线敷设方式研究

Pipeline laying modes of mine industrial site

陕晋蒙地区近年来降雨量增多,使得地下水位上升,导致部分埋地敷设的管线、管沟位于地下水位以下,存在一定安全隐患。因此,需要对煤矿矿井工业场地的管线敷设方式进行分析比较。本文阐述了矿井工业场地的管线布置原则与敷设方式。以大海则煤矿为例,对管线埋地敷设及架空敷设2种方案进行技术及经济比较,发现陕晋蒙地区2种管线敷设方式的造价相差不大,但埋地敷设具有安全可靠、保温性好的优点,故推荐采用埋地的管线敷设方式,同时应充分考虑地下水位影响,合理确定场地及管线设计标高。

The rainfall in Shaanxi,Shanxi and Inner Mongolia has increased in rencent years,causing the rise of groundwater level.As a result,some buried pipelines and trenches are below the groundwater,which poses a potential safety risk.Thus,it is necessary to analyze and compare the pipeline laying modes of mine industrial sites.This paper mainly expounds the layout principle and laying mode of pipeline,and taking Dahaize Coal Mine as an example,carries out the economic and technical comparison of two pipeline laying modes.It is pointed out that for Shaanxi,Shanxi and Inner Mongolia regions,no great difference was observed between the cost of the two laying modes.Considering the buried laying has the advantages of safety,reliability and good thermal insulation,it is recommended that the buried pipeline laying mode should be adopted.At the same time,the influence of groundwater level should be fully considered,reasonably determining the site and marking height of pipeline.
