【 摘 要 】

In the paper the petrographic characteristics of coal from waste dump of abandoned mine Gruve 2 in Logyearbyen, Svalbard are described. The coal samples originated from a dump of waste material, situated near the mine entrance. The microscopic petrographic features as well as random reflectance were tested. Basic chemical-technological parameters as moisture Wtar, ash content Adb, volatile matter content Vdaf, total sulphur content Stdb and gross calorific value Qsdaf were assigned. The samples examined belong to medium rank D (ortobituminous coals), macerals of the vitrinite group prevail in the coals' petrographic composition. The coals analyzed are characterized by low ash and sulphur content but high volatile matter content and mean values of the combustion heat.
