浅析大中型箕斗解体安装方案在盲竖井中的应用

Discussion on the Application of Sorting and Installation Scheme of Skip in Blind Shaft

简要介绍了大中型箕斗的安装形式,详细介绍了解箕斗体后逐段安装方案在玲珑金矿盲竖井中的应用。针对大中型箕斗需要先解体分段经巷道和罐笼运输至盲竖井井口再进行重现组装的情况,通过箕斗受力分析,综合采用高强度法兰连接、铰孔螺栓定位和错开解体位置等方法和工艺,对箕斗进行了解体方案设计。解体设计克服了箕斗体积大、解体组装变形大及连接强度低等困难,使解体后重新组装的箕斗满足了设计强度和使用要求,成功解决了盲竖井大中型箕斗解体后安装难题。

Briefly introduced the installation methods of large and medium-sized skip, details of the application after the disintegration of pieeewise installation scheme in blind shaft,Linglong gold mine.In view of the large and medium-sized skip need to collapse to implement the segmentation assembled by wellhead roadway and cage to transport the blind shaft, through the site condition and equipment force analysis, integrated with high strength flange connection,reaming bolt positioning and stagger the collapse location method and process,designed the scheme of skip disintegration.The scheme of skip disintegration overcome the skip size,disassembly and assembly of large deformation,the connection strength is low,making detailed and reasonable skip sorting scheme,successfully resolved the problem of the installation of large and medium-sized skip in blind shaft after the disintegration.
