Lead and zinc mining activity in Poland

Some facts of lead and zinc mining in Poland

XI Cen. - first mining activity in Olkusz region (Lead and Silver)
1299 - Foundation of city Olkusz (by German law)
1356

- King Kasimir the Great gives to the city special privileges

(Olkusz was 1 of 6 the most important centres of

Małopolska)

1551

- King Sigmuntus August introduced special mining law

for Olkusz miners,

XVI

- construction of dewatering tunnel system,

1814

- First Lead and Zinc mines „Josef”, Ulises” and „Jerzy”

(1823) have been opened ,

1815

- Olkusz become a city in Polish Kingdom and begins great

economical prosperity (time of Stanislaw Staszic).

XX cen.- The biggest and the fastest development of the region

caused by mining activity.

Lead and zinc mining activity in Poland

Most important threats of

the Lead and Zinc mining in

Olkusz Region

Lead and zinc mining activity in Poland

Most important factor of the Lead and Zinc mining in Olkusz Region

Exploitation in the region is threated by:

1. Water

•

Extremely high water inflow is registered in the region (the

highest in the world).

In 1998 inflow of 366 m

/min

has been

registered.

•

There are 6 pumping stations installed underground with 66

pumps and total pumping capacity of 840 m

/min.

•

All main openings are driven as a two parallel galleries, one of

which is only for water.

2. Methane gas (in the past)

•

In the past a very intensive water inflow directly from the

surface, brought to the mine some organic components

(sulfolignian) producing methane gas.

One methane

explosion has been registered in the past !!

Example of planned shaft bottom of the „Zawiercie” Mine

AGH University of Science and Technology Kraków

Conclusions:

1. Present world metal demand suggests great interest

of developing Lead and Zinc mining,

2. Development of „Olkusz” metal mining region should

introduce following suggestions:

•

Replacing the vertical shafts hoisting by inclines
transprtation.

•

Existing industrial infrastructure (processing plants
and metallurgical plants) should be used also for
future production. The ore and the concentrate can be
transported by existing railway, by trucks or by modern
belt conveyer.

AGH University of Science and Technology Kraków

Conclusions:

•

New mines should have a preliminary treatment plants
(crushers).

•

For ventilation of the new mines there are plans to use
extra ventilation wide dimension boreholes

•

New generation of mining machines of high matching
to thickness of the ore body (drilling, bolting, loading
and transporting) have to be constructed and apply.

•

Instead of explosive a new generation of road header
can be used.

•

Transportation of the ore from the mine up to the
surface can be managed by trucks or belt conveyers.

AGH University of Science and Technology Kraków

Conclusions:

3. Polish experience in ore mining is good enough to

introduce new standards in exploitation lead and zinc,
according to market demands.

4. In shallow part of the ore body open pit mining is

available. This depend on neighbourhood of National
Parks what limits such kind of mining.

5. About 60 Mt of flotation waste are on the ponds with a

content of 0.8 % metal including ca. 460 000 t of zinc
metal.
