摘要
研究表明石上井田B_(4)煤层原煤为中高灰、中硫、中高发热量焦煤;浮煤为特低灰、中硫、特高发热量的煤;煤岩类型以亮煤为主。B_(4)煤层厚度与发热量、硫分,挥发分与硫分,发热量与硫分、灰分,硫分与灰分呈现较好相关性。其中发热量与灰分相关性显著,相关系数为-0.989;B_(4)煤层灰分呈现南翼中部较高、深部高于浅部特征;挥发分呈现东部较低、深部高于浅部分布特征;发热量最高分布在东西两翼,浅部低于深部;硫分西部较高,浅部低于深部。
The study shows that the raw coal of B_(4) coal seam in Shishang Mine Field is medium ash,medium sulfur and high calorific coking coal.Float coal is the coal with extremely low ash,medium sulfur and high calorific value.The coal rock type is mainly bright coal.B_(4) coal seam thickness and calorific value,sulfur content,volatile and sulfur content,calorific value and sulfur,ash content,sulfur and ash content show a good correlation.The correlation between calorific value and ash content was significant,and the correlation coefficient was-0.989.The ash content of B_(4) coal seam is higher in the middle of the south wing and higher in the deep than in the shallow.Volatiles were lower in the east and higher in the deep than in the shallow.The highest calorific value was distributed in the east and west wings,and the shallow part was lower than the deep part.Sulfur content is higher in the west and lower in the shallow than in the deep.
