贵州赫章腾达煤矿的煤岩与煤质特征分析及评价

Analysis and evaluation on coal petrography and coal quality characteristics of Tengda coalmine,Hezhang county,Guizhou province

介绍了腾达煤矿的概况及其煤质特征,指出区内煤层煤具有中-高灰、特低挥发分、中高-高发热量、较高-高热稳定性等特征,且煤层硫分变化大,介于低硫煤-中高硫煤之间。全区可采煤层煤均为无烟煤三号,可作动力用煤。

This paper introduced the geologic general situation of Tengda exploration area, and analyzed their coal characteristics. The research of coal quality indicated that the coal seams had characteristics such as medium-high ash, super low volatile matter, medium-high and high calorific value, relatively high and high thermal stability, and the sulfur content had a larger changing range, which ranged from low sulfur content to high sulfur content. According to coal classification standard, coal from all minable coal seams were anthracite （WY3）, which could be used for power generation.
