摘　　要：通过对下峪口煤矿不同开采工艺的已开采工作面瓦斯涌出特点的考察,分析了煤与瓦斯突出矿井回采工作面的瓦斯涌出量影响因素。认为不同开采工艺采面的瓦斯涌出有不同的特点,分层开采时上分层时是瓦斯集中涌出的焦点,同时采面的瓦斯涌出量受煤层埋深、煤层厚度、地质构造、邻近煤层等方面的影响,需要根据采面瓦斯涌出的主控因素来制定应对措施。In terms of the characteristics of gas emission from the mining faces of different mining technology, the influencing factors of the gas emission of coal and gas outburst coal mining face are analyzed. It is considered that the different mining technology of the working faces have different characteristics with the gas emission, the higher delamination is the focus of the gas emission when slice mined, the gas emission from the working face are affected by the depth of the coal seam, the thickness of the coal seam, the geological structure and the adjacent coal seam, thus it is necessary to formulate the response according to the main control factors of the gas emission.
