为了对矿井深部煤层瓦斯含量随埋深的变化形态做出新的研究和探讨，以某矿区煤层瓦斯含量与埋深数据为例，采用基于一元非线性回归理论的数学方法，提出一种适合该矿区煤层甲烷带内瓦斯含量随煤层埋深相关关系较好的双曲线型数学模型；在其有效拟合区间内，通过该数学模型对矿区井田内深部瓦斯含量进行预测．结果表明，该矿区井田内相同煤层埋藏深度下实测瓦斯含量同模型预测瓦斯含量能够较好吻合，说明该模型对本矿区井田内瓦斯含量的预测是可靠的．此外，通过吸附常数a值与模型极限值的比较结果，可进一步验证数学模型的预测精度．

As the exploitation of a coal mine is gradually extending to the deep area, the environment of exploi- tation has become more and more complex, and gas disaster also becomes serious. It becomes particularly im- portant to grasp the change law of gas content in deep area. By making the correlation analysis of gas content and coal seam depth in the methane zone of a mining area, a fitting curve of hyperbolic was chosen. Through the mathematical models of the curve which can effectively fit the known data, the deep gas content of mine was predicted, and then the mining practice was guided. In addition, proposed new ideas might further vali- date the model~ accuracy through the comparison between the result of the adsorption constant value and that of the model limit.
