贵州省织纳煤田煤炭资源潜力评价

织纳煤田含煤地层上二叠统为海陆交互相沉积,含煤层数多,厚度大,煤质较好。通过区内含煤性、煤层煤质及聚煤规律研究,对煤炭资源潜力及勘查开发前景做出综合评价。以向斜构造为基本单元划分了15个赋煤单元和2个赋煤小区,共圈定了81个预测区,预测2000m以浅潜在资源量334.325 6亿t,探获资源储量191.646 0亿t,总资源量525.971 6亿t,并提出煤炭资源勘查开发利用建议:6个近期部署区优先安排普查,10个中期部署区考虑安排预查,9个远期部署区目前暂不宜开展勘查工作。

Coal Resource Potential Evaluation in Zhijin-Nayong Coalfield,Guizhou Province

Coal-bearing strata in the Zhijin-Nayong coalfield belong to Upper Permian Series and contain multiple coal seams with large thickness and good coal quality. Through studies on coal-bearing property, coal seam, coal quality and coal accumulation pattern, comprehensively evaluated prospect of resource potential, exploration and exploitation. Taking the syncline structure as elementary unit has divided the coalfield into 15 coal hosting units and 2 coal hosting subareas. Totally delineated 81 prediction areas, have pre-dicted potential resources 33.43256 billion tons, reserves 19.16460 billion tons, total resources 52.59716 billion tons. Meanwhile, sug-gestions on coal resource exploration and exploitation put forward：6 near future deployment areas should give priority in arranging for prospecting, 10 midterm deployment areas should arrange reconnaissance, and 9 long-term deployment areas temporarily should not be carried out investigation works.
