对思绵煤矿0.4 m极薄煤层从技术和经济两方面进行评价,论证其可采性。通过分析可知本项目技术可行,具有较强的盈利能力和抗风险能力。把工业指标最小可采厚度从0.6 m降为0.4 m,为矿井后续开采提供了稳定资源条件,并且为云南、四川等地区相似地质条件的薄煤层开采提供了借鉴依据。
The 0.4 m thin seam of Simian Coal Mine is evaluated from both technical and economic aspects to demonstrate its recoverability. Through the analysis shows that the project is technically feasible, with strong profitability and anti-risk ability. The minimum recoverable thickness of the industrial indicator is reduced from 0.6 m to 0.4 m, which provides a stable resource condition for subsequent mining and provides a reference for the mining of thin coal seams with similar geological conditions in Yunnan and Sichuan.
