浅议新元矿井建井期间安全高效通风技术

Discussion on the Safe and Efficient Ventilation Technology during the Construction Period of Xinyuan Coal Mine

新元矿井建井初期采用立井开拓方式,立井到底后,如仍采用地面通风,仅能满足4个掘进工作面的用风需求。为满足安全高效的施工要求,通过分析比较两种通风方案,选择在中央进、回风井井筒安装4趟玻璃钢风管作为假回风,实现了矿井建设期间的全负压通风,通风能力可满足15个掘进工作面生产,保证了矿井安全生产。

Adopts the pioneering way of vertical shaft mine, it can only satisfy the wind demand of four tunneling during the initial period of construction in Xinyuan coal faces using the ground ventilation. In order to satisfy the safe and efficient construction requirement, analyzes and compares the two ventilation schemes, chooses that installs four glass steel wind ducts as false return air, realizes all negative pressure ventilation during the construction period of the coal mine, delivery volume can satisfy the production of fifteen tunneling faces.
