摘要
针对黄白茨煤矿12#煤层,采用钻孔径向测定法进行了煤层透气性系数的测定。介绍了煤层透气性系数测定方法的种类。合理地选择了12#煤层1203综采工作面的瓦斯抽放方法。为矿井合理地选择瓦斯抽放方法提供了科学依据,有效地治理了工作面上隅角的瓦斯,确保了工作面的安全生产。
According to the the 12# coal seam at Huangbaici coal mine,using radial drilling determination method to measure coal seam gas permeability coefficient,the types of gas permeability coefficient measuring methods are introduced.The gas drainage method of 12# coal seam 1203 mechanized working face is reasonably selected,which provides scientific basis for reasonably choose gas drainage method,effectively controls workface upper corner gas,ensures safety production of workface.
