| 摘 要： | 从瓦斯地质学的观点出发,将反映煤层瓦斯基本参数的空间变化规律看做是与其赋存地质条件密切相关的连续函数。结合趋势面拟合及其模型优化的原理和方法分析得出了淮北矿业集团公司芦岭煤矿井田范围内瓦斯含量的变化及分布与其位置坐标的对应数值关系,依据该数值关系可对矿井深部采场和未开采区域实施比较准确、可靠的定量瓦斯预测。该方法也适用于其他具有相似特征的瓦斯地质变量分析。

| Abstract: | According to the gas and geology theories, the space changing rule of basic parameters reflecting gas in coal bed can be regarded as a continuous function closely related to geology condition. Considering this point and by applying trend surface fitting method and its principles of model optimization, the correspondingly numerical relations between the change of gas content and its spatial distribution in Luling coal mine are obtained, based on this result, an accurate, reliable and quantitative forecast of gas in deep stopes and unexploited region can be achieved. This method is also applicable to the analysis of other gas and geology variables with similar characteristics. |
