新峰一矿深部煤层地质及煤质特征研究

分析了新峰一矿地质特征，区内发现长度超过1 km的断层7条，对二₁煤层造成不同程度的破坏，研究了煤层地质及煤质特征。研究得出，可采煤层为1层，二₁煤层层位稳定，总厚度8.88 m，煤层结构简单，其稳定程度属较稳定类型。揭露含煤地层总厚度480.76 m，含一煤至七煤共7个煤组，含煤共13层，总厚15.72 m；二₁煤层属高灰、特低硫、特高热值煤，煤类主要为瘦煤，个别见煤点见有焦煤、贫煤、贫瘦煤，工业用途主要可作炼焦配煤使用，也可作动力用煤。研究对促进地方经济发展，提高居民收入有积极意义。

Study on geology and coal quality characteristics of deep coal seam in Xinfeng No.1 Mine

This paper analyzes the geological characteristics of Xinfeng No.1 Mine，and finds seven faults with a length of more than 1 km in the area，which causes different degrees of damage to the Ⅱ₁ coal seam.The coal seam geological and coal quality characteristics are also studied.The study shows that the mineable coal seam is 1 layer，the Ⅱ₁ coal seam is stable，the total thickness is 8.88 m，the coal seam structure is simple，and its stability is a relatively stable type.The total thickness of the exposed coal-bearing strata is 480.76 m，including 7 coal groups from 1 to 7，with a total of 13 coal-bearing layers，with a total thickness of 15.72 m.The Ⅱ₁ coal seam is high ash，ultra-low sulfur，and ultra-high calorific value coal，and the coal is mainly thin coal，there are coking coal，lean coal and lean lean coal in individual coal spots.The industrial use can be mainly used for coking coal blending，and also for power coal.The research has positive significance for promoting local economic development and increasing residents′ income.
