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。
To research the gas emission and distribution during production of fully mechanized top coal caving face in the gas outburst mine, taking the ＋ 735 coal mining face of Dahuangshan Coal Mine as the engineering background, field measurement was conducted using element method, the data of gas distribution was collected, which was analyzed and studied, obtaining the gas emission characteristic in the gas outburst mine with approximate ＂U ＋ L＂ type ventilation, and the law of gas distribution and migration along the working face and in the vertical direction of the coal wall.
