| 煤炭开采受环境条件约束和开采技术限制。作为计算煤炭可采资源量的两大指标，硫分、煤层厚度一直是限制煤炭可采资源量大小的重要因素。本文在前人研究的基础上，基于煤层硫分和厚度两个约束条件，分析了山西不同硫分、不同厚度无烟煤的资源量。研究发现，山西中厚层低硫无烟煤仅占全省无烟煤保有资源总量的37%，保有资源量相对不足，应节约开采与使用。适合高炉喷吹的特殊无烟煤资源量仅占全省无烟煤保有资源总量的29%，约151亿t，应进行战略性保护；全省高硫无烟煤占全省无烟煤保有资源总量的23%，其中晋城矿区高硫无烟煤占到矿区无烟煤保有资源总量的38%，实现煤中有机硫的高效脱除可以解放大量高硫无烟煤；山西拥有薄层中低硫无烟煤42亿t，开采具有重大经济价值。 |

| Coal mining is restricted by environmental conditions and mining technology. As two major indexes for calculating the amount of recoverable coal resources， sulfur content and seam thickness have always been two important factors limiting the amount of recoverable coal resources. Based on the previous research， the resources of anthracite with different sulfur content and thickness in Shanxi Province are analyzed based on the two constraints of sulfur content and thickness. It is found that the medium-thick low-sulfur anthracite in Shanxi Province only accounts for 37% of the total reserves of anthracite in the province， and the reserves are relatively insufficient. The special anthracite resources suitable for blast furnace injection only account for 29% of the total anthracite resources in the province， about 15.1 billion tons， which should be strategically protected. The high-sulfur anthracite accounts for 23% of the total anthracite resources in the province， and the high-sulfur anthracite accounts for 38% of the total anthracite resources in Jincheng mining area. The efficient removal of organic sulfur in coal can liberate a large amount of high-sulfur anthracite. Shanxi has 4.2 billion tons of thin layer medium and low sulfur anthracite， which has great economic value. |
