交岔巷道风桥设计方案与施工工艺探讨

Crossing roadway wind bridge design and construction technology discussion

为了满足巷道独立通风或运输的要求,将已有的同一标高相通的两条交岔巷道通过风桥改造成上下两条独立的巷道,文章以陈四楼煤矿北翼总回风巷与北部西翼集中皮带巷交岔点处风桥施工为例,采用风桥改造巷道的方法既可在短时间内达到相应目的,又能减少巷道工程量并优化巷道空间位置关系,有利于尽快完成巷道的系统改造工程,对巷道交岔点施工技术的研究具有指导意义。

In order to meet the requirements of independent ventilation or transportation of the roadway, the existing two intersections of the same elevation through the wind bridge into two separate up and down the roadway, the article to the fourth floor of the north wing of the total return airway and North West The method of using wind bridge to rebuild the roadway can reach the corresponding purpose in a short time, but also reduce the engineering quantity of the roadway and optimize the space position relation of the roadway. It is propitious to finish the roadway as soon as possible. System reconstruction project, which is of instructive significance for the study of construction technology of roadway intersections.
