我国煤田地质条件复杂，煤层的透气性低，鉴于我国煤储层的特点，借鉴火烧油层、煤的地下气化以及注热、注二氧化碳对提高煤层气产出机理上，本文提出一种地面强化开采煤层气的新方法一火烧煤层开采煤层气，其实施步骤主要包括井网的布置、煤层的贯通、煤层的点燃、煤层气的采集以及煤层燃烧范围的控制，并讨论避免井下爆炸应注意的问题。

The geological conditions are complicated, and permeability of coal is low in China. In view of the characteristics of coal seam reservoir, and based on the mechanism of combustion of oil seam, coal gasification, injection of heat and carbon dioxide to enhance the yield of CBM, a new method is proposed by the paper to intensify extraction of CBM on surface, i.e. combustion of coal seam. The main steps of the method include pattern arrangement, connection of coal seams, ignition of seams, collection of CBM, control of combustion range, and discussion on points for attention in order to avoid underground gas explosion.
