灾变时期,在某些条件下,为了抢救井下人员避免遭有毒气体的侵袭、防止灾变扩大,有时需要迅速地把矿井总风流的方向反转过来,这就叫做矿井反风。实现矿井反风要靠主要扇风机的反风设备。为此,我国《煤矿安全规程》第125条对矿井反风的要求(包括时间要求和风量要求)以及反风设备的选择、维护和可靠性等都作了明确具体的规定。本文主要目的是如何理解和贯彻执行这些规定。
During the catastrophic period, under certain conditions, in order to rescue downhole personnel to avoid the invasion of toxic gases and prevent the catastrophic expansion, it is sometimes necessary to quickly reverse the direction of the total mine air flow, which is called mine anti-wind. Mine anti-wind to rely on the main fan wind machine. To this end, China’s “Coal Mine Safety Regulations” Article 125 of mine shaft requirements (including time requirements and air volume requirements) as well as the selection, maintenance and reliability of the anti-wind equipment have made clear and specific provisions. The main purpose of this article is how to understand and implement these rules.
