高瓦斯井下综放工作面瓦斯防治技术的应用

 摘要 ：高瓦斯矿井采用综合机械化放顶煤开采技术，使工作面单产大大提高，煤炭生产更加集中，但是预防和处理瓦斯也成了安全生产的最大的难题之一。老虎台矿在多年的实践中，成功的运用了预抽瓦斯、边采边抽瓦斯和采空区瓦斯抽采技术，解决了综放面瓦斯集中涌出的难题，保证综放面连续安全生产，并充分利用了瓦斯资源。

Applecation of hihgh gassy mine gas prevention and controlTrchnology of fully mechanized caving

SummaryHigh gas mine using comprehensive mechanized coal caving mining technology, make face per unit area yield is greatly improved, coal production is more concentrated, but the prevention and treatment of gas has become one of the biggest problems in safety production. Laohutai mine in practice for many years, the successful use of the preliminary drainage of gas, gas and draining while mining goaf gas drainage technology, solves the fully mechanized caving face gas gushing problem, ensure the fully mechanized caving face of successive safe production, and make full use of the gas resource.
