柴达木盆地北缘控煤构造样式与赋煤规律

运用构造控煤分析方法，在系统分析柴达木盆地北缘煤田构造样式的基础上，将该地区控煤构造样式划分为6种类型，并分别讨论了它们的成因及其与煤系赋存之间的关系，从而查明了柴达木盆地北缘地区煤系赋存的基本规律.结果表明：隆起区前锋带构造变形强烈，控煤构造样式以逆冲断层组合为特征，煤层被抬升变浅有利于开采，但破坏较为严重，因而煤矿开采规模较小；凹陷带内部应力应变较弱，控煤构造样式多以断－褶型和单斜断块组合为特征，煤系赋存较为稳定，其浅部应成为今后煤田勘探开发的重点.

Coal-controlled structural styles and coal occurrence regularity in northern Qaidam Basin

Using the analytical method for structure controlling coal,the coalfield structural styles were system studied in northern Qaidam Basin. Based on the analysis results,the coal-controlled structural styles were classified into six types,and their genetic and the relationship with coal occurrence regularity were discussed,and the occurrence regularity of coal measures was found out.The conclusions indicate that the tectonic deformation is intense in the front of the uplifted belts,the coal-controlled structural styles are characterized by the combination of reverse faults,the coal seams are uplifted to the shallow and easy to be exploited,but the scale of mines is small because of the serious damages of coal seams.On the contrary,the stress-strain is weak in the depressions,the coal-controlled structural styles are characterized by fault-fold and fault-monocline,and the occurrence of coal seams is stable,the shallow of the depressions should become the key areas of coalfield exploration and development.
