摘要
为了防治由于煤层开采强度、深度及瓦斯涌出量的增大而造成工作面瓦斯浓度的超限情况已成为煤矿开采中的重大安全隐患。文章通过对寺河矿大采高工作面多巷道布置进行相似材料模拟和现场试验,提出了三进两回的通风方式,使工作面通风系统得到优化,一定程度上解决了工作面瓦斯超限问题。多巷布置对高产高效工作面瓦斯治理技术研究具有重要意义,文章初步建立了工作面瓦斯治理的框架,为今后类似条件的工作面瓦斯治理提供了参考依据。
Gas overrun due to increasing mining strength, depth and gas emission in the working face has become a major coal mining safety hazard. By employing similar material experiment and field test on multi-roadway in Sihe Coal high mining face, we put forward a ventilation type of intake air for three times and return air for two times, which can optimize ventilation system and solve the working face gas overrun problem in a certain extent. Multi-roadway layout in high efficiency working face is important in studying gas control technology. We preliminarily establish the framework for gas treatment in working face, which provides a valuable reference basis for gas treatment under the similar conditions.
