Selective coal mining of intercalated lignite deposits

Journal Article:

Abstract

Describes selective coal mining in the Tamnava-Istocno Polje coal surface coal mine (Yugoslavia), designed for an annual coal production of 11.4 Mt. Until 1991, this mine exploited one thick lignite seam, without spoil intercalations, using a bucket wheel excavator-conveyor-spreader system both for coal mining and removal of overburden. In the future, several spoil intercalations of up to 1.0 m and thicker will appear with a total volume of 22 million m{sup 3}. These intercalations have to be selectively excavated in order to guarantee the calorific value of coal for the Nikola Tesla power plant. Computer calculations were carried out to determine the decrease in excavator coal production due to selective mining of spoil strata. Calculations found that the annual surface mine capacity will be lower by at most 9%, depending on thickness of spoil intercalations. The useful operation time of excavators will be reduced by 98 hours per year. The planned annual coal production will nevertheless be fulfilled. 3 refs.
