焦作煤田五里源井田煤质特征分析

摘要

焦作煤田五里源井田构造位于太行山隆起带的东南缘，本区赋存煤层层数较多，但发育稳定且厚度较大，具有工业开采价值的仅有二1煤层和一2煤层。区内二1煤层为低水分、低中灰、特低挥发分、特低硫、低磷分、抗碎强度高、可选性好、热稳定性能好、高灰熔性、特高热值的无烟煤；一2煤层为低水分、低灰、特低挥发分、高硫、较低—中等灰熔性、特高热值的无烟煤二号。%Wuliyuan well filed locates at the southeastern edge of the uplift zone of Taihang Mountain as well as the composite part of Neocathaysian tectonic system and Qinling-Kunlun latitudinal tectonic system. The occurrence of coal seam is layered with stable development and big thickness, onlyⅡ1 coal seam andⅠ2 coal seam have industrial exploitation value;Ⅱ1 coal seam is anthracite of low moisture, medium to low ash, low volatile, low sulphur, phosphorous,high crushing strength, good washability, thermal stability, high ash fusibility and high heating value;Ⅰ2 coal seam is No.2 anthracite of low moisture, low ash, low volatile, high sulphur, low to medium ash fusibility, high calorific value.
