摘　　要：基于煤层瓦斯分布规律和瓦斯含量预测来指导矿井瓦斯预抽、制定合理的矿井生产作业制度和煤层气的开发。在分析造纸房井田地质构造特征的基础上,定性、定量地分析了影响矿井瓦斯赋存的地质因素,得出矿井瓦斯赋存规律,绘制出C7号煤层瓦斯地质图,得出了C7号煤层瓦斯含量沿煤层倾斜方向基本上是随着埋深的增加而增大,在矿区东南部埋深大于300 m时,瓦斯含量最大值为18 cm3/g。The seam gas distribution law and the gas content prediction was applied to guide the mine gas pre-drainage and to set up the rational mine production operation regulation and the rational development of the coal bed methane.Based on the analysis on the geological structure features of the Zaozhifang Minefield,the geological factors affected to the mine gas deposits were qualitatively and quantitatively analyzed.The mine gas deposit law was obtained.The gas geological map of C7 seam was drawn.The gas content of C7 seam was increased with the depth increased along the seam inclined orientation.At the south-east part of the mining area with a depth less than 300 m,the max value of the gas content was 18 cm3/g.
