煤矿瓦斯抽放技术研究

Study on gas drainage technology in coal mine

对于高瓦斯矿井,防治瓦斯是其中必不可少的环节,瓦斯抽放开采无疑是最有效的瓦斯治理方式,通过瓦斯抽放开采降低矿井瓦斯涌出量及回采工作面的瓦斯涌出量,实现矿井安全生产。本文阐述了本煤层瓦斯抽采、邻近煤层瓦斯抽采及采空区瓦斯抽放方法的作用及适用条件,并对瓦斯抽放工艺及设备进行了研究。

For high gas coal mine, the prevention and control of gas has also become a essential link, pumping gas exploitation is undoubtedly the most effective gas governance, through the gas drainage mining reduce mine gas gushing quantity and mining working face gas volume fraction, the realization of the safe production of the mine. This paper expounds the function and applicable conditions of gas drainage and gas drainage in the coal seam gas drainage, adjacent coal seam gas drainage and gas drainage area, and studies the technology and equipment of gas drainage.
