Złoża surowców mineralnych i zmiany środowiska naturalnego wywołane przez górnictwo na terenie Bukowna
(Wydawnictwa AGH, 2005) Wójcik, Andrzej J.; Chmura, Janusz
Complicated geological structure characterise the area of research. Big geological units in this region (Upper Silesian Coal Basin, Cracow Monocline) are separated by big and deep fault zone (Sławków Trough). Exploitation of natural resources existing in this area (zinc and lead ores, quaternary formations of sand) has led to enormous changes in the environment. As a result of restricting and finally closing down mining (zinc ores and sand mines) the area gradually regains its natural as well as tourist and recreational value. There are also a few places in the town especially distinguished to preserve them in unchanged form (i.e. Sztoła River Valley, Diabla Góra Hill).

Badania mułów węglowych i odpadów niemineralnych w zakresie możliwości otrzymania paliw
(Wydawnictwa AGH, 2005) Kuczyńska, Iwona
Alternative fuels are becoming more and more popular due to the depletion of power resources, high cost of usage and growing awareness of the threats posed to natural environment. This paper introduces results of preliminary tests on obtaining fuel from waste, which also proves to be an effective method of waste utilization based on mixing carbon loam with non-mineral waste, by pelletization. The granulated product received in this way could become an alternative fuel in power engineering, heat engineering, cement kilns or domestic fire. The research proves also that granulates of the highest quality are those created from mixing carbon loam with wooden, tobacco and tanning dust.

Ekologiczne i ekonomiczne uwarunkowania wykorzystania zasobów przy produkcji kruszyw łamanych
(Wydawnictwa AGH, 2005) Czopek, Kazimierz
There are in production process of broken aggregates the contrary ecological and economic purposes. From ecological point of view it should be tried to do the maximization in using up resources. So far the production of aggregates needs to use several stages of feed crushing. As the effect there is created more and more small fractions treated as waste. From economic point of view the best situation would be to sell the highest price (the most expensive) fraction: chippings, voussoir, breakstone. The mediate solution can be to offer the lowest granulation fractions. This paper describes the optimum way of choice in this matter, concerning the kind of mineral necessary for recast process, demand of aggregates, prices of particular fraction of aggregates.

Estimation of the range of fractured zone in the roof of underground roadways using the seismic method
(Wydawnictwa AGH, 2005) Jarosz, Jacek
It is a well-known truth that each mining activity changes the natural stress field in the rock mass. Driving of underground roadways leads to the appearance of a fractured zone around the excavated space. Separated and fractured roof rocks of underground roadways possess significant danger to the safety of people working in the mine. Knowledge of the thickness of the fractured zone is very important to the process of protecting roadways and particularly to determine conditions of roof bolting. A new way of use of a seismic method to estimate the parameters of fractured zones is described in this paper. The Love-type interference waves generated by hammer blows in roadway roof rock are discussed. The results of field measurements in a coal mine are presented.
