鸳鸯湖矿区以不粘煤为主,长焰煤次之,是良好的煤化工和动力用煤。从煤岩特征,煤的筛分、浮沉、煤及矸石的泥化程度试验等方面,对矿区及各井田煤的可选性特征进行了研究,研究表明:清水营井田煤中粘土类矿物较多,可选性较差,其它井田可选性相对较好;矿区煤中粘土矿物多呈细胞充填状,惰质组含量较高,难选出灰分很低的煤;当浮煤灰分控制在6.00%～11.00%,浮煤产率大于80%,煤为中等可选—易选;煤遇水易泥化,矸石为高泥化程度。研究结果可为煤的洗选工艺设计提供依据。
Yuanyang Lake mining non-stick to the main coal, flaming coal second, is a good coal chemical and power coal. From the characteristics of coal and rock, coal screening, drifting, coal and gangue degree of mud test, etc., the coal mine and the mine field coal optional features were studied, the study shows that: coal mining clay water minerals than mine field And the selectivity of other fields is relatively good. The clay minerals in the coal mines in the coal mines are mostly in the state of cell filling, and the content of inertinite is high, making it difficult to select the coal with low ash content. When the fly ash content is controlled at 6.00% ~ 11.00%, floating coal production rate is greater than 80%, coal is medium optional - easy to choose; coal easy to muddy water, gangue high mud degree. The results provide the basis for coal washing process design.
