Local leveling geoid 2015 model (LGOM 2015) presents the best fit in comparison to the quasigeoid determined by the satellite measurements (average residual [+ or -]3.6 mm).
However, for geoidpol2008C, PL-geoid-2011 and LGOM 2015 models the results are slightly worse.
Analyzes of the standard quasigeoid models and recently developed local leveling geoid 2015 (LGOM 2015) model showed that the local model is the most accurate one.
On the basis of this research it can be concluded that recently developed LGOM 2015 model can be used for precise applications such as satellite leveling over the test area.
On the basis of data concerning the technical condition of the traditional building development of LGOM and the mining tremors occurring there, the index [a.sub.sg] was established, which represents an aggregated impact of seismic events that affect an object through its whole life-period.
The research was carried out on a group of traditional brick, residential buildings from LGOM. Altogether, the database contains information concerning the structure, damage and technical condition of 724 objects.
In the work of WODYNSKI and Lasocki (2002) a twofold mining tremors effect on the technical condition of the building of LGOM was considered.
Such an approach to the evaluation of impact accelerating the wear of an object often involves the whole seismic history of the thirty years of mining exploitation in LGOM. The only presently available information on this history are the mining seismic catalogs.
The relation, developed on the basis of data from the range of E [member of] [[10.sup.6], 2.5 x [10.sup.9]], r [member of] [300, 8700], is supposed to be suitable for the whole area of LGOM.
A considerable part of the analysed database of LGOM contains information about buildings for which the epicentral distances from some tremors were very short.
