By above research, the following results are obtained.(1)The extracting module of aero-radioactive thematic information is integrated with ENVI, the remote sensing image processing software;(2) Based on the IDL, the computer program modules extracting following uranium thematic information have been developed, including initial uranium contents, active uranium contents, uranium migration coefficient, uranium information strengthen, uranium D-value and variance Ratio etc, al. Some of kalium special information extracting modules are also developed;(3)Based on the IDL, the aero-radioactivity information multi-parameter focus analysis module is developed;(4) It is proposed that a lots of phenomenon of uranium immigrating exist in Keping-Kuche are in the Neocene period. Because of the uranium pre-enrichment, the areas with high uranium content were formed in Neozoic and Quaternary. The above migration uranium are also the abundant source for uranium ore-forming in favorable strata of Mesozoic and Cenozoic system;(5)There are obvious uranium immigrating and enrichment in Eastern Portion of Keping Block Uplift, Yinate-Laolongjiang, and Qidaoban-KuChe.

通过对鄂尔多斯盆地神木地区上古生界含煤岩系中煤储层的纵横向分布、宏观煤岩类型、微观煤岩组分、孔隙结构与渗透性、镜质体反射率和吸附性能等方面特征的研究，认为：煤层总厚呈东西厚、南北薄的分布特点，煤层厚度满足煤层气开发的要求；多为半亮煤，仅东部边缘地带以半暗煤为主，表现为低含水、中等灰分含量和高挥发分含量的烟煤；煤岩显微组分中，镜质组含量最高，其次为惰质组；孔隙类型以微孔、过渡孔为主。
