宁东煤田侯家河勘查区煤质特征分析

Analysis of the Features of Coal Property of Houjiahe Prospecting Area of Ningdong Coal Field

宁夏宁东煤田侯家河勘查区的煤炭是宁东能源化工基地建设可持续发展的重要储备资源。侯家河勘查区煤层也是宁东煤田鸳鸯湖矿区煤层向东、向深部的延续部分。通过侯家河勘查区与鸳鸯湖矿区的煤质对比,反映侯家河勘查区煤质特征及变化。侯家河勘查区的煤为不黏煤,特低灰、低硫、特低磷、高发热量,煤对二氧化碳的反应性较高、中热稳定性、焦油产率低,较低软化温度灰,中等可选～易选,是良好的动力、液化、气化、煤化工等用煤。

The coal in Houjiahe prospecting area of Ningxia Ningdong coal field is the important sustainable developmental reserve resources in the construction of energy and chemical industry base in Ningdong. The coal seam of Houjiahe prospecting area is also the eastern and deep constitutions of the coal seam of Ningdong Yuanyang Lake mining area. By comparing of coal property between Houjiahe prospecting area and Yuanyang Lake mining area, the features of coal property of Houjiahe prospecting area and its change are reflected. The coal in Houjiahe prospecting area is non-caking coal with the features of ultra-low ash, low sulphur, ultra-low phosphorus, high heat, high reaction to carbon dioxide, middle heat stability, low tar yield, lower softening temperature, middle optional ~ easy optional, which is the good coal that can be used in motive power, liquefaction, gasification and coal chemical industry.
