| 摘 要： | 以大峰矿地质勘探煤质资料为基础，采用Surfer和AutoCAD绘制了下组煤五煤灰分、挥发分、硫分、发热量等值线图，总结了五煤煤质变化规律。结果表明:灰分、发热量在矿区中心变化最明显；从矿区边缘向中心，灰分逐渐增加，至矿区中心达到最高；发热量逐渐降低至矿区中心达到最低。矿区中心部位的煤质相对稍差，东西靠近边界部位煤质稍好。圈定的无烟煤范围为大峰煤矿下组煤五煤的合理配采和煤炭产品质量调控提供依据。

Variation and distribution law of coal quality lower seam No.5 in Dafeng mine |
| |
| Abstract: | Based on coal geological exploration data of Dafeng mine, the paper used Surfer and AutoCAD to draw the contour maps of ash, volatile, sulfur and calorific value of the lower seam No.5, summed up the law of coal quality variation of seam No.5. The results show that the ash and the carorific value change the most obviously in the center of the mine; ash content increaes gradually from the edge to the center of the mine and reaches the maximum in the center, carorific value decreases gradually and is the lowest in the center.The coal quality is relatively poor in the center and slightly better in the east and the west near mine boundary. The delineated scope of anthracite provided the basis for reasonable mining of lower seam No.5 and regulation and control of the quality of coal product in Dafeng mine. |
