以卫星遥感技术为主要手段,采用SPOT与ETM遥感卫星数据,通过多源遥感地质解译,结合野外调查验证,综合常规煤田地质资料的研究分析,对巴基斯坦旁遮普省Dalwal-Padhar地区的煤炭资源赋存特征开展系统分析。重点开展了控煤构造、含煤地层及煤层分布和沉积变化特征、聚煤作用、后期构造对煤层的改造等综合分析,认为巴基斯坦Dalwal-Padhar构造活动强烈,Patala组含煤地层沉积环境稳定性差,且受后期多期次构造改造的作用明显,整体的含煤性较差,主要在南部Bhal、Dhariala地区一带较为稳定,适合小煤窑开采,对解决该区的缺煤现状有一定的实际意义。同时,在南亚低山丘陵浅覆盖地区成功应用遥感技术进行煤炭资源调查评价的实践表明,多源遥感技术可高效实现对控煤构造和含煤地层的控制,提高煤炭资源调查的效率,为今后在类似地区应用遥感技术进行煤炭资源调查工作提供了宝贵的技术参考。

With satellite remote sensing technology as the main means, SPOT and ETM remote sensing satellite data are usedto carry out a systematic analysis of the occurrence characteristics of coal resources in Dalwal Padhar of Punjab Province,Pakistan by multi-source remote sensing geological interpretation, and combined with field survey verification and comprehensive research and analysis of conventional coal field geological data. The author focuses mainly on analysis of the coalcontrolling structure, coal bearing strata, distribution and sedimentary change characteristics of coal seams, coal accumulationand the transformation of coal seams by late structures. It is believed that the Dalwal-Padhar structure in Pakistan has strongactivity, and the sedimentary environment of the Patala Formation’ s coal bearing strata is poor in stability. The overall coalcontent is poor due to significantly affected by multiple late structural transformations. It is mainly stable in the southernBhal-Dhariala and suitable for small coal kiln mining, which has practical significance for solving the coal shortage issue inthis area. At the same time, the successful application of remote sensing technology in coal resource investigation and evaluation in low mountain and hilly regions of South Asia has shown that remote sensing technology can effectively control coalcontrolling structures and coal bearing strata, improve the efficiency of coal resource investigation, and provide valuable technical reference for future coal resource investigation viaremote sensing technology in similar regions.
