大水头煤矿综放工作面瓦斯治理技术实践

摘要

In the ventilation system design of working face, the drainage drilling parameter selection and the safety technology measures development, Dashuitou Coal Mine considered the gas geology as the prerequisite for gas control and had gained good effect of fully mechanized caving face gas treatment, and achieved continuous 20 annual production safety.%大水头煤矿在工作面通风系统设计，抽放钻孔参数选择、安全技术措施制订中，以矿井瓦斯地质作为治理瓦斯的先决条件，治理综放工作面瓦斯效果良好，实现了连续20年安全生产。
