王洼煤矿扩大延伸勘探区煤质特征

Coal Seam and Coal Quality Characteristics in the Extended Exploration Area of Wangwa Coalmine

通过对王洼煤矿扩大延伸勘探区可采煤层煤的煤岩特征、物理化学性质和工艺性能的分析研究,阐述了该区可采煤层煤的煤质特征及其变化规律:该区各可采煤层煤的显微有机组分中镜质组含量大于惰质组,二者约占89%,壳质组占1%左右,煤的无机组分占10%左右,并以粘土矿物为主。水分含量在8%左右,该区自西向东煤的灰分产率、挥发分产率、硫分、水分逐渐降低,属特低灰—低灰、低—中硫、特低磷—低磷,中高—高挥发分,高热值、不具粘结性的长焰煤、不粘煤。

The physical, petrological, chemical and technical properties of coals in the extended exploration area of Wangwa coalmine were analyzed. On this basis, the authors illustrated the area＇s mineable coal seam quality characters and variation regularity： The vitrinite is bigger than inertinite, the two accounts for about 89%, the exinite accounts for about 1% in the maceral organic component. The coal inorganic component accounts for about 10% by mainly clay minerals. The moisture content （Mad） is about 8%, ash content, volatile matter, sulfur content and moisture reduce gradually from west to east in the area, the coal belongs to especially low - low ash, low - medium sulfur, especially low phosphorus - low phosphorus, medium high - high volatile matter, high calorific value, no caking property long flame coal and non-caking coal.
