摘要
针对大阳煤矿工作面由U+I型通风方式改为U型通风方式,工作面风排瓦斯能力大大降低的问题,分析了工作面回采期间瓦斯涌出比例构成,针对本煤层和邻近层(采空区)的瓦斯抽采措施提出了6个可行性方案,运用模糊数学方式选取了工作面瓦斯抽采的最优方案。
In order to solve the problem that gas drainage capability of working face was weakened dramatically after the U＋I-shaped ventilation was replaced by U-shaped, this paper analyzed gas influx proportion composition during back mining, and proposed 6 feasible alternatives for gas drainage measures of current and nearby coal seams. Fuzzy mathematics methodology was conducted to choose the optimal scheme for gas drainage at workingface.
