矿井通风系统中调节风窗作用探析

Analysis on the role of regulation windscreens in the system of ventilation

从理论上分析矿井风量调节中调节风窗的作用机理,通过双鸭山矿业集团煤矿通风系统改造实例说明风窗的安设引起矿井风量及风压发生变化,从而加快局部地点瓦斯涌出等一系列问题,提出在矿井设计及实际生产中,科学设置调节风窗,在保证用风地点风量基础上,确保安全生产的观点。

Theoretically , mechanism of regulation windscreens in mine air volume adjustment was analyzed, The change of air volume and pressure because of installing windscreens through was illustrated examples of coal mine in Shuangyashan Mining Group ventilation system, which would speed up the local gas emission. The perspective of scientific installation of with would wind shutters, and ensure safety in production on the basis of enough air volume in mine design and actual production were proposed.
