Abstract

Bulursk anthracite from the Omsukchan Basin is comprehensively analyzed. A new method of pneumatic separation of anthracite is proposed, yielding a concentrate of ash content 6–8%. Samples of the concentrate are analyzed. By up-to-date methods, the composition, petrographic characteristics, calorific value, pore structure, and thermomechanical and physicochemical properties of anthracite in various size classes (75–100, 50–75, 25–50, and 13–25 mm) are determined. Potential applications of the anthracite are identified, mainly in metallurgy.

评估 Bulursk 无烟煤的效用

摘要

对鄂木舒盆地的Bulursk无烟煤进行了综合分析。提出了一种新的无烟煤气选方法，可得到灰分含量为 6-8% 的精矿。分析浓缩物样品。通过最新的方法，对不同尺寸等级（75-100、50-75、25-50 和 13-25 mm）无烟煤的成分、岩相特征、热值、孔隙结构以及热机械和物理化学性质进行了研究被确定。确定了无烟煤的潜在应用，主要是在冶金方面。
