| 摘 要： | 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。

| Abstract: | The Hongdunzi mine area is situated in the recent new coal resources area in the Ningxia Hui AR with large area and considerable coal resources.After analyses of coal physical properties and coal petrological characteristics,chemical properties and technological performances,have considered that the coal in the area has high volatile matter,medium~high ash,low~high sulfur,low phosphorus,medium calorific value,medium~strong caking property,high thermal stability,high softening temperature,hard to grind and washing.Coal rank belongs to gas coal;raw coal or flotation cleaned coal can be used as coals for coking,power and gasification. |
