蟠龙至高家屯勘查区煤炭资源评价与开发前景

Coal resource evaluation and development prospect of Palong and Gaojiatun exploration areas

蟠龙至高家屯勘查区位于鄂尔多斯盆地之延安单斜中部,地质构造简单,含煤地层为三叠系上统瓦窑堡组,可采煤层有3层,属于薄~中厚煤层,煤炭总资源量为27 426万t。通过勘查区地质、煤层及煤质分析研究,对煤炭资源潜力与开发前景做出综合评价,认为区内可采煤层埋藏较浅、层位稳定、煤类优良、潜在工业价值较大,具有较好的开发前景。

Panlong and Gaojiatun exploration areas are located in the central Yan＇an monocline structure of Ordos Basin. In the exploration areas,the geological structure is simple,the coal-bearing strata is the upper Triassic Wayaobao group,there are 3 layers of mineable thin and medium thick coal seam and the total amount of coal resources is 274. 26 million tons.Through the analysis of geological exploration,coal seams and coal quality in the exploration areas,the coal resources potential and development prospects were comprehensively evaluated. The research shows that the coal seam buried depth is shallow,seam occurrence is stable,the coal class is good,the potential industry value is big and there is good development prospect.
