我国应用有底柱崩落法采矿的矿山,根据矿体贮存特点,在实践中创造了许多电耙道的通风方案,为改善电耙道的通风条件提供了良好条件。本文主要是介绍这些矿山的电耙道通风系统,并对某些存在问题提出改进意见,供参考。我国部分采用有底柱崩落法矿山的通风简况见附表。一、部分矿山电耙道的通风根据通风系统的特点,有底柱崩落法电耙道通风可分为矿块式和采区式两种类型。 (一) 矿块式通风电耙道的矿块式通风是一个矿块的电耙道由单独的进、回风井巷组成一个独立的风路系统。新鲜风流由矿块的人行通风天井经联络道到电耙道排入矿块回风井巷。
In our country, the mines with bottom column caving method are used for mining. According to the characteristics of ore body storage, many electric rake ventilation schemes have been created in practice, which provides good conditions for improving the ventilation conditions of electric rake. This paper mainly introduces the electrical rake ventilation system of these mines and puts forward some suggestions for improving the existing problems for reference. Part of China’s use of bottomed column caving mine ventilation briefing schedule. First, the ventilation of some mine electric rake Road According to the characteristics of the ventilation system, there are two types of electric rake air ventilation at the end of the column caving method can be divided into two types of ore block and mining area. (A) mine block ventilation rake Road mine block ventilation is a mine block electric rake by a separate intake and return airways to form an independent airway system. Fresh air flows from the pedestrian ventilation of the Patio Road through the contact Road to the electric rake Road into the mine block return airway Lane.
