红墩子矿区位于银川市黄河以东,矿区面积较大,煤炭资源量可观。从煤的物理性质、煤岩特征、煤的化学性质和工艺性能等方面分析,认为矿区的煤具有高挥发分、中—高灰、低—高硫、低磷、中热值、中—强粘结,高热稳定性、高软化温度灰、较难磨、较难选的特点,煤类为气煤,原煤或浮选后的精煤可作为炼焦用煤、动力用煤、气化用煤等。
Hongdunzi mine is located in the east of the Yellow River in Yinchuan City, with a large mining area and a considerable amount of coal resources. According to the physical properties of coal, the characteristics of coal and rock, the chemical properties and technological properties of coal, the coal in the mining area is considered to have high volatility, medium-high ash, low-high sulfur, low phosphorus, Bonding, high thermal stability, high softening temperature of ash, more difficult to mill, more difficult to choose characteristics of coal gas coal, raw coal or flotation of coal can be used as coking coal, power coal, coal gasification Wait.
