中文摘要：

以焦作煤田古汉山井田为研究区，通过定性分析与定量研究，探讨了煤层埋深、顶底板岩性、煤层埋深以及地质构造等因素对煤层含气性的控制；通过数理统计的方法，得出了埋深、有效埋藏深度以及煤厚与煤层含气量的回归方程，并对回归方程进行了显著性检验．研究结果表明，煤厚、断裂构造以及埋深是影响古汉山井田煤层气赋存特征的主要因素，并表现为：①随着煤厚的增加，含气量线形增大．②随着埋深和有效埋藏深度的增加，含气量先是急剧增大，到了一定阶段后，增大趋势变慢，之间具有对数正相关关系．③在断层尖灭端，含气量大，断裂带内含气量小；正断层的下降盘的含气量大于上升盘，同一正断层的上升盘附近，距离断层面越远，含气量越大．煤层的顶板岩性对含气量有一定的影响，但不是引起井田内煤层含气量变化的主控因素．

英文摘要：

By using qualitative and quantitative analysis, the influence of the factors on gas-bearing properties, such as, burial depth and thickness of coal seams, lithology of roof and floor rocks, and geology structures has been discussed. Through mathematical statistics, the regression equations of relationship among burial depth, effective burial depth, thickness of coal seams and gas content has been gained and the test of significance on the equation was done. The results show that burial depth, seam thickness and fault structures are the main factors of the influence on the existence characteristic of coal gas in Guhanshan coalmine. The actual features are： Frist, with the increase of coal seam thickness, gas-content increases in linearity mode; Second, the relationship among burial depth, the effective burial depth and gas-content is positive correlation in a logarithm; Third, the gas-content is higher at the vanishing end of faults and is lower in the zones of faults. Gas content in down-thrown side of normal fault is higher than that in upthrown side with increase of the distance from faults, and becomes higher near the up-thrown side of the same normal fault. The feature of the roof and floor rocks has a certain influence on gas content, but not the main controlling factor on the change of gas-content in Guhanshan coalmine.
