正宁县罗川东部煤炭资源分布特征研究
|
摘要
通过对正宁县罗川东部煤炭资源勘查区研究,查明目的层段延安组共发育3个主要煤层组。可细分为5个亚煤层,其中煤5-1层主要分布于研究区北部,经济资源量分别为2 440.87万t;煤5-2层在全区大范围发育,经济资源量约14 100.52万t;煤8层在中北部呈东西向条带状发育,是次要可采煤层,经济资源量1 190.68万t。三层可采煤均为不粘煤(BN31),建议建产应优先考虑煤5-2层,兼顾煤5-1层。罗川区可采煤层的分布与资源量的查明将对正宁县煤炭工业具有重要经济价值。
Through the study of the coal resource exploration area in the eastern part of Luochuan County, Zhengning County, it was found that the Yanan Formation of the target interval has developed three main coal seam groups. It can be subdivided into 5 sub-coals, of which coal 5-1 is mainly distributed in the northern part of the study area, with economic resources of 24,408,700 tons; coal 5-2 layers are widely developed in the whole region, and the economic resources are about 141.052 million tons. The 8 th coal layer is developed in the north-west direction and is a secondary coal seam with an economic resource of 11.96 million tons. The three-layer coal mining is non-stick coal(BN31). It is recommended that the coal production should be given priority to coal 5-2, taking into account the coal 5-1 layer. The distribution and resource of the recoverable coal seam in Luochuan District will be The coal industry in Zhengning County has important economic value.
