| 摘 要： | 通过对新疆主要煤田的煤炭资源分布特征，煤变质特征及构造特征分析，探讨新疆的煤层气资源赋存特征，对新疆主要煤田煤层气资源的勘探开发潜力进行初步评价，新疆的煤层气基本属于少生中储型，虽然单位含气量较低，但煤炭资源非常丰富，且相对集中，煤气具有较大的勘探开发潜力。

| Abstract: | The coal resource total of Xinjiang takes lead in China. The uneven distribution of coal resources is clear. Over 90 percent of coal resource total come from Junggar basin, Turpan basin, Ili basin and northern margin of Tarim basin. The main coal formations occur in the Jurassic of which the Middle Jurassic possesses 73 percent and Lower Jurassic 23 percent. The carboniferous and Permian contain some small-scale coal resources. The Jurassic smoke coal that formed during intermediate metamorphism predominates large coal fields. The matrurity of coal is mostly medium. The microsopic coal compositions are different among different coal fields, but mostly are glassy and inert components with high absorption. The exploration and development of coal resources are preliminarily appraised as below. The coal bed methane is low in generation, and medium in reserve, bu the great abundance and concentration of coal resources prove its good potential. Favourable pool generation conditions of coal bed methane are available in south Junggar coal field, Kubai coal field, and some coal mines in Turpan-Hami basin and Ili basin. |
