在前人总结的矿石在溜井中的移动规律及特点的基础上，通过对经常发生井筒堵塞事故的黑沟矿高深溜井的观测，发现高深溜井在垂直全断面连续性矿石移动区之上存在垂直全断面阶段性矿石移动的特性，该特性是由溜井中流动矿石散体的搭拱效应所产生，井筒中拱的形成和破坏交替进行，从而使矿石的放出呈现脉动过程；由此归纳总结出高深溜井井筒中矿石移动存在垂直全断面阶段性移动、垂直全断面连续性移动、变速变向全断面移动和变速变向局部断面移动的规律；通过分析揭示了垂直全断面阶段性矿石移动的特性是造成溜井井筒堵塞、片帮、磨损、矿石分级混合等现象出现的重要原因；同时，对于在用的高深溜井提出井筒黏结拱堵塞处理技术，针对设计与新建的溜井提出井筒结构设计上的建议以预防堵塞；为破解高深溜井井筒出现的故障开拓了思路，对同类型溜井的设计和生产实践有重要的指导意义。
在前人總結的礦石在霤井中的移動規律及特點的基礎上，通過對經常髮生井筒堵塞事故的黑溝礦高深霤井的觀測，髮現高深霤井在垂直全斷麵連續性礦石移動區之上存在垂直全斷麵階段性礦石移動的特性，該特性是由霤井中流動礦石散體的搭拱效應所產生，井筒中拱的形成和破壞交替進行，從而使礦石的放齣呈現脈動過程；由此歸納總結齣高深霤井井筒中礦石移動存在垂直全斷麵階段性移動、垂直全斷麵連續性移動、變速變嚮全斷麵移動和變速變嚮跼部斷麵移動的規律；通過分析揭示瞭垂直全斷麵階段性礦石移動的特性是造成霤井井筒堵塞、片幫、磨損、礦石分級混閤等現象齣現的重要原因；同時，對于在用的高深霤井提齣井筒黏結拱堵塞處理技術，針對設計與新建的霤井提齣井筒結構設計上的建議以預防堵塞；為破解高深霤井井筒齣現的故障開拓瞭思路，對同類型霤井的設計和生產實踐有重要的指導意義。

Based on ores movement regularity and characteristics of the mine shafts from the previous,through the obser-vation of deep shafts in Heigou mine where wellbore plugging accident often occur,the deep shafts existence characteristics of vertical full section phase ores moving is found on top of the vertical full section continuous ore moving zone. This feature is generated by the arches effect of the ores flow in the shaft,and the formation and destruction of the arches in the wellbore are carried out alternately,so that the ores discharge shows like the pulse;It is concluded that the deep shafts ores movement rules include the phase movement of the vertical full section,the continuous movement of the vertical full section,the variable speed and direction movement of the vertical full section and the variable speed and direction movement of the vertical part section;The characteristics of phase and vertical full section ores movement is the important reason for wellbore plug,wall caving,wear and ore mixing and grading by analysis. At the same time,the processing technology of the plugging wellbore is put forward for the present deep shafts, For the design and construction of the new shafts, the design form of wellbore structure to prevent blockage is put forward;It opens up the new idea for trouble clearing appearing in deep shaft,and this idea is an important guiding significance on the design and practice of production of the same type of deep shafts.
