长材料下井方法及其相关设计

Method of transporting long material in shape to pit-bottom and correlational designs

根据煤矿生产的特点及要求 ,分析长材料通过立副井或进风井下井的操作过程 ,以及副井或进风井的井底马头门高度、井口套架的不可拆梁最低高度等有关参数的确定方法。论文结合具体工程设计进行了探讨。

According to characteristic and demand of coal mine producing,this paper analyzes operating course of transporting long material in shape to pit-bottom in auxiliary shaft or entering wind shaft,and method of designing the high of pit-bottom;the minimum high of fixed girder of pit-shaft structure and other correlational parameters.This paper give an example for exploring.
