摘要
寺河矿东井区初步评估为煤与瓦斯突出矿井,文章依据煤与瓦斯突出矿井瓦斯抽采要求,从地面井瓦斯抽采、回采工作面瓦斯抽采、掘进工作面瓦斯抽采等方面设计了瓦斯抽采方法,并从瓦斯抽采率、抽采时间和抽采负压三个方面分析了瓦斯抽采参数,验证了寺河矿东井区接替盘区瓦斯抽采设计是完全有效的,通过瓦斯抽采确保矿井安全高效的生产。
The preliminary assessment result of Sihe coal mine east shaft area was coal and gas outburst mine, according to the gas drainage requirement of coal and gas outburst mine, the gas drainage methods were designed, comprising ground gas drainage, mining face gas drainage and driving face gas drainage, the gas drainage parameters were analyzed, such as drainage rate, drainage time and suction pressure, the drainage effect was verified, the design was effective, ensuring the safe and high- efficiency production.
