Practices on Pressure Balanced Mining Technology of Coal Mining Face in Seam with Short Distance to Above Seam

文章主要阐述了近距煤层下层工作面均压开采期间,为防止有害气体下泄,工作面均压系统的建立方法及步骤。对均压应急响应系统、均压安全监管系统的布置形式、建立过程和技术特点做了详细介绍,文章的研究对于近距煤层下层工作面均压开采具有科学意义和工程指导价值。

The paper mainly stated the establishment method and procedure of the pressure balanced system in the coal mining face in order to prevent the harmful gas released during the pressure balanced mining of the coal mining face with a short distance to above seam. The paper had a detail introduction on the layout mode of the pressure balanced emergency response system and the pressure balanced safety monitoring and control system, the establishing process and the technical features. The study would have the scientific significance and project guidance value to the pressure balanced mining of the coal mining face with a short distance to above seam.
