摘　　要：晋城矿区晋普山煤矿目前开采9煤层,煤层瓦斯含量高,经鉴定属高瓦斯矿井。利用井田地质勘查成果及井下瓦斯监测数据,对区内瓦斯赋存规律及涌出量进行了分析。结果显示:煤层煤类、褶皱构造和煤层围岩是其主要控制因素,而煤层埋深对瓦斯赋存影响不明显。按开采层和邻近层瓦斯涌出量叠加原理,采用分源预测法分别预测了9、15号煤层回采工作面瓦斯涌出量,其绝对瓦斯涌出量均大于5 m3/min,局部瓦斯含量较高,具有煤与瓦斯突出危险,建议矿井做好防范瓦斯灾害相应措施。The Jinpushan coalmine is currently mining coal No.9 with high gas content in the Jincheng mining area identified as a gassy mine. Using minefield geological exploration results and underground gas monitoring data, have analyzed gas hosting pattern and emis- sion in the area. The result has shown that coal seam, coal rank, folding structure and country rock are the main gas hosting controlling factors, while the impacting from coal buried depth is not obvious. According to extracting seam and neighboring seam gas emission su- perposition principle, using source prediction has predicted production face gas emissions from coal seam Nos.9 and 15 respectively. Their absolute gas emissions are all larger than 5 m3/min and higher locally, thus have existed coal and gas outburst hazard, and corre- sponding measures to prevent gas disasters suggested.
