THE
Mini Maritsa Iztok
is at the beginning of the technological
process for power generation by Maritsa
Iztok thermal power plants. We have been
specializing in the extraction of energy raw materials from an indigenous source for more than half
a century now.
Mini Maritsa Iztok
EAD operates the largest lignite field in
The electric power
generated within the Maritsa Iztok Complex
accounts for more than 25% of the total power generation in
Specialists from State
Mines Company, Pernik, commenced geological exploration activities in the
In the course of
several years the geographic boundaries of the coal field and its reserves amounting to more than 2.9 billion tonnes of
coal were established.
The first project
for exploration was prepared in 1951 by GIPROSHAHT,
The construction
of Troyanovo 1 Mine was launched in
1952, and later in 1962 and in 1964 the construction of Troyanovo North Mine
and Troyanovo 3 Mine started
respectively.
In the 70s a
scheme for mining development was adopted. It involved two mines – Troyanovo
North Mine and Troyanovo South Mine. The latter comprised Troyanovo 1 Mine and Troyanovo
3 Mine.
The stability of
the mine boards and dump slopes is of essential importance for the safety and
efficiency of the mining operations. Stabilization calculations are made by
using a unique calculation scheme with prism for active pressure and
mathematical model (of no equivalence in
the global mining industry), which to the largest extent correspond to the
exceptionally difficult engineering and geological conditions in the
The stability of
boards is calculated monthly and computer programs designed by Bulgarian
engineers are used in this process.
Specialized
software is used for the processing and analysis of the enormous volume of
geological information, as well as for maintenance purposes and updating the
geological database.
