摘要: 为了对瓦斯突出矿井综放工作面生产过程中瓦斯涌出与分布规律进行研究,以大黄山煤矿+735工作面为实际工程背景,运用单元法对综放工作面进行现场实测,采集瓦斯分布数据,并对所采集数据进行处理分析和研究,得到了瓦斯突出矿井近似“U+L”型通风方式下综放面瓦斯的涌出特征,以及沿采面方向、垂直煤壁方向的瓦斯分布、运移规律,为相似赋存条件下的煤层开采和瓦斯防治提供一定的借鉴。

Abstract: In order to research the emission and distribution about gas in in the production process of fully mechanized top coal caving face in the gas outburst mine, taking the Mount Huangshan +735 coal mining face as engineering background, using the element method to measure in fully mechanized top coal caving face , collecting the data of distribution of gas , and the data collected are analyzed and studied, so got high gas mine approximate "company U+L" type ventilation in fully mechanized caving face under the gas, and along the vertical direction, coal mining face wall direction gas distribution, migration, provide certain reference to the coal mining and gas prevention occurrence in similarly conditions .

Key words: fully mechanized coal face, gas emission, gas distribution, "U+L", type
