中文摘要：

本文通过铁法矿区煤层埋深（压力和温度）、岩浆后期侵入、煤阶、含水量及煤中无机组分和显微组分含量等几方面分析了研究区域内煤层甲烷吸附能力，进而探讨了铁法矿区煤层气含量及其控制因素。分析认为：研究区煤层气含量各煤层差异性较大，埋深、原煤挥发分、原煤水分、灰分产率等因素对煤层气含量均有一定的影响。总体而言，煤层的埋深（压力和温度）以及岩浆的后期侵入是影响本区煤层气含量的主要因素。

英文摘要：

Systematic study is carried out on absorbing capacity of CBM as well as controlling factors in Tiefa Mining Area Conclusions are made as the following： the difference of gas content in seams is comparatively big in the Area. Factors such as buried depth, volatile matter of raw coal, water content and ash content in raw coal can produce influence upon gas content to some extent. Major factors affecting gas content are buried depth of coal seams （pressure and temperature） and magma intrusion.
