摘要
在当前形势下,实现煤炭资源的保障,要立足国内供给,加大煤矿资源潜力评价和地质勘查,挖掘自身潜力,利用自身优势,寻找新的后续矿源。以某煤炭区域地质情况为背景,研究了煤田沉积环境特征、测井响应特征、煤层分布特征、煤层物理性质、煤岩特征以及煤类。研究得出,某煤炭区可采煤层为赋存在山西组下部的二1煤层,煤层厚度0.15~10.57 m,平均厚4.11 m,属大部分可采的中厚煤层、结构简单,二1煤层为中灰、中硫、高热值贫煤和无烟煤,区内二1煤层的稳定程度属较稳定煤层。研究对该地区煤炭工业发展具有一定的指导意义。
Under the current situation,to achieve the guarantee of coal resources,it is necessary to base on domestic supply,increase the potential evaluation of coal mine resources and geological exploration,tap its own potential,and use its own advantages to find new follow-up mine sources.Based on the geological conditions of a coal region,studying the characteristics of the coalfield sedimentary environment,logging response characteristics,coal seam distribution characteristics,coal seam physical properties,coal rock characteristics and coal types.The study showed that the recoverable coal seam of a coal region was theⅡ1 coal seam that occurs in the lower part of the Shanxi Formation.The thickness of the coal seam was from 0.15 m to 10.57 m,with an average of 4.11 m.It belonged to the majority of the minable medium thick coal seams and has a simple structure.TheⅡ1 coal seam was composed of medium ash,medium sulfur,high calorific value lean coal,and anthracite coal.The stability of theⅡ1 coal seam in the area was relatively stable.The research has certain guiding significance for the development of coal industry in this region.
