摘要
以拟建茶山矿区急倾斜采空区影响的潜江-韶关段管道为研究背景,从开采完成和采动过程中急倾斜采空区对管道影响进行研究。分析采空区地表变形移动对输气管道的影响,给出管道安全初步评价方法,并利用概率积分法对急倾斜采空区场地的管道安全进行预测评价,研究对以急倾斜煤层采空区场地敷设管道的安全运营有重要意义。
This study takes the proposed pipeline of Qianjiang-Shaoguan section which affected by steeply inclined goaf in Chashan mining area as the research background.The influence of steeply inclined goaf on the pipeline were studied from the completion of mining and the mining process.Weanalyzed the influence of surface deformation and movement of goaf on gas pipeline,gave a preliminary evaluation method of pipeline safety,and used probability integral method to predict and evaluate pipeline safety in steeply inclined goaf site.Therefore,it is of great significance for the safe operation of pipelines to study the law of pipe-soil interaction and deformation properties in the goaf of steeply inclined coal seam.
