| 摘 要： | 瓦斯涌出规律直接关系到矿井通风设计、管理和瓦斯灾害的防治效果,研究瓦斯涌出在时空上的分布具有较大实用意义。运用瓦斯地质理论,依据实际瓦斯涌出资料和地质勘探资料,研究发现煤层上覆基岩厚度和顶板20 m范围泥岩厚度是寺河煤矿东区瓦斯涌出的主控因素,构建了瓦斯涌出多元回归预测模型,准确绘制了绝对瓦斯涌出量等值线图,为矿井通风设计、管理和瓦斯防治提供科学依据。

| Abstract: | Law of gas emission directly affects mine ventilation design and management and the control effect of gas disaster.,and it has more applicable significance for the research of the space-time distribution of gas emission.According to actual gas emission data and geological exploration data, the factors affecting gas emission were investigated by gas-geologic theory in the east area of Sihe Coal Mine.It was found in study that the thickness of overlying bedrock and mudstone within 20 meters roof were the premier control factors affecting gas emission in the east area of Sihe Coal Mine.The prediction model of gas emission in working face was established with Multiple Regression Method and the isoline map of absolute gas emission was accurately drawn.The results can provide the scientific application base for mine ventilation design and management and the control of gas disaster. |
