Geological factors influencing the possibilities of deformations in the shafts of the Legnica-Głogów Copper Area (LGOM)
(Wydawnictwa AGH, 2012) Sieradzy, Karolina; Matwij, Wojciech
On 23$^{rd}$ March 1957 the information appeared that in the Sieroszowice region copper rich shale had been discovered. Probably nobody realized how difficult the conditions of copper ores exploitation would be. On 4$^{th}$ April 1959 the team lead by Jan Wyżykowski presented the first geologic documentation of the Lubin-Sieroszowice deposit. Based on the results from 24 boreholes, the reserves of the deposit were estimated as more than one billion tons of the ore (Błądek et al. 2005). Decision to build a mining enterprise, consisting of four mines, was taken immediately.

The comparison of the results of laser scanning and classical surveying methods of measuring the area and volume in the chapel of St. Kinga in the salt mine of Bochnia
(Wydawnictwa AGH, 2013) Maciaszek, Jadwiga ; Madusiok, Dominik; Matwij, Wojciech
Providing a long durability of the historic salt mine of Bochnia demands proper observations, analyses and drawing conclusions based on them and leading to recognising and the assessment of a specific behaviour of the rock mass and the effectiveness of the protection from mining damage. The studies of the rock mass and surface deformation are carried out by the mine based on the results of the observations made with the methods of surveying. These observations include, among others, the measurements of the height of benchmarks stabilized on the surface and rock mass, the measurements of linear convergence (on the established vertical and horizontal bases in selected chambers of the mine) and since 2003 the attempts have been made to apply total stations and laser scanners to document the selected chambers. The article presents test studies on laser scanning carried out in the chapel of St. Kinga in the Bochnia Salt Mine in 2007 and 2013 (Fig. 1). They showed high accuracy of the scanning method both in the positioning of points of the salt excavation, in modelling, as well as calculation of the area of any cross-section (Fig. 2) and the volume of chambers of complicated shapes (Fig. 3). The carried out accuracy studies, analyses and comparisons were used in the calculation of the area convergence for the chapel of St. Kinga in the Bochnia Salt Mine. They make base for the calculation of volume do convergence in the near future.

Surveying support in geophysical methods
(Wydawnictwa AGH, 2014) Matwij, Karolina ; Matwij, Wojciech
Traditional methods to identify the geological structure of the rock mass are based mainly on the analysis of cores from boreholes. Today, more and more often geophysical methods are introduced to support classical methods or completely replace them. One of the major advantages of this type of measurement is non-invasive analysis of the rock mass.

Praca przybliża zagadnienie powstania i ewolucji pienińskiego pasa skałkowego. Autorzy podjęli szerokie badania mające na celu pogłębione obserwacje jego skomplikowanej struktury, którą charakteryzuje występowanie wymieszanych ze sobą różnowiekowych elementów litologicznych pochodzących z różnych facji. Badania pienińskiego melanżu obejmowały kartowanie geologiczne, badania stratygraficzne i strukturalno-tektoniczne, które zostały zintegrowane z danymi pochodzącymi z badań grawimetrycznych, sejsmicznych i geoelektrycznych. Mimo że historia geologiczna centralnego pienińskiego pasa skałkowego została już odtworzona wcześniej i został zrekonstruowany cykl wydarzeń geologicznych, które ukształtowały jego obecną strukturę, to w wyniku podjętych badań udało się pozyskać nowe dane pozwalające na pełniejsze poznanie melanży z tego obszaru.
