| 中文摘要: |
| 低阶煤占中国已发现煤炭资源量的58%,充分开发和利用低阶煤,对于煤炭资源清洁高效利用具有重要的战略意义和经济、环境价值。山西拥有低阶煤资源量251.28亿t,占全省已查明保有煤炭资源总量的9.28%。山西低阶煤主要有长焰煤、弱粘煤、不粘煤以及少量褐煤,主要分布在山西晋北煤炭基地大同矿区、朔南矿区、河保偏矿区和平朔矿区,合计占全省低阶煤资源量的97%。山西的长焰煤具有低水分、中灰、中挥发分、高硫、高热值的显著特点；大同组的弱粘煤低灰低硫,山西组弱粘煤灰分较高,太原组弱粘煤中灰中硫；不粘煤为低灰中硫。山西低阶煤拥有资源和区位集中、保有资源量大、长焰煤资源优势明显、动力煤供应充足四大特点,具有良好的分级分质利用和整装开发潜力。 |
| 英文摘要: |
| Low-rank coal accounts for 58% of the coal resources discovered in China. Full development and utilization of low-rank coal has important strategic significance and economic and environmental value for the clean and efficient utilization of coal resources. Shanxi has 25.128 billion tons of low-rank coal resources, accounting for 9.28% of the province ’s total coal resources. The low-rank coal is mainly distributed in the Datong mining area, the Shuonan mining area, the Hebaobao mining area and the Pingshuo mining area, which together account for 97% of the province's low-rank coal resources; The long-flame coal resources in Shanxi have the remarkable characteristics of low moisture, medium ash, medium volatile matter, high sulfur, and high calorific value; The weak clay and low ash and low sulfur in the Jurassic mining area, The ash content of weakly sticky coal in Shanxi Formation is high, Sulfur in ash in weakly sticky coal of Taiyuan Formation. Non-stick coal is low ash and medium sulfur. Shanxi's low-rank coal resources are concentrated in resources and location, with large reserves, long flame coal resources, obvious advantages, and sufficient supply of thermal coal. It has good potential for graded and quality utilization and package development. |
