摘要
上隅角CO浓度的超限是影响工作面安全生产的主要因素之一。针对大同鹊山矿上隅角CO浓度超限事故的案例,通过"调风、堵漏、加快进度"等综合治理措施,使上隅角CO浓度降低到安全值以内,保障了工作面的安全生产。
CO concentration overrun in upper corner is a major influential factor of safety production on the working face.According to the CO concentration overrun accident in Queshan Mine,with the comprehensive treatment of air regulation,plugging,and progress acceleration,the CO concentration dropped to a safety range,which guaranteed the safe production.
