摘　　要：针对1405综放工作面实际生产情况,制定了高位抽放、本煤层抽放及上隅角抽放相结合的瓦斯抽放方法。采取瓦斯抽放综合措施以后,上隅角瓦斯浓度控制在0.7%以下,回风流瓦斯浓度控制在0.5%以下,保证了1405工作面的正常开采,对类似地质条件的工作面开采具有一定的借鉴意义。Aiming at the production actual situation of 1405 fully mechanized top-coal caving, developed a gas drainage method that combined a high drainage ,the coal seam extraction and upper comer drainage. After adopting gas drainage comprehensive measures, the upper comer gas concentration is less than 0.7%, the gas concentration of the return airflow is below 0.5%, which ensures the normal 1405 working face mining, has certain reference significance for the similar geological conditions mining.
