摘要:
准格尔煤炭国家规划矿区是内蒙古众多优质煤产地之一，其矿区含煤面积大，地质构造简单、煤层埋藏浅、煤层厚度大，属于开采条件优良的矿区。煤质特征是影响煤价值的重要因素，对煤的经济价值及环境的影响都十分重要。通过对矿区内4、5、6、8、9等主要可采煤层的煤岩特征、工业分析(Mad、Ad、Vdaf)、全硫、发热量及元素分析等一系列测试与统计分析，发现其具有丝碳含量高及灰分产率高、挥发分高、全硫低及有害元素含量低的特点，全煤田平均发热值为22.36 MJ/kg。综合分析认为其为良好的动力用煤。
Zhungeer national planning coalfield with features of large coal bearing area, simple geological structure, shallow buried coal seam, thick coal seam and excellent mining conditions is one of the high-quality production areas of coal in Inner Mongolia. The characteristic of coal is an important factor to influence the coal value, economic value and environment. The results that the coal with the characteristics of high fusinite content, high ash and volatile, low total sulfur and harmful elements were found through a series tests and statistical analysis of characteristics of coal petrology, industry analysis (Mad, Ad, Vdaf), total sulfur, calorific value and elemental analysis of 4, 5, 6, 8 and 9 coal seams. The average calorific value of coal is 22.36 MJ/kg. Zhungeer coal is applied to the power through comprehensive analysis.
