    The area of Legnica-Głogów Copper District is a mining region. Hence it is the area where mining tremors occur. There are three mines located in the area, each having its own underground seismological system locating arisen tremors. On the basis of these records tremors are being located. But there is also a surface measurement system which is controlling trembles caused by mining tremors. The aim of this thesis is to present the possibility of localization mining tremors coming from mines located on the Legnica-Głogów Copper District has been tested on the basis of the data registered by accelerometer sensors deployed on the surface. The data were taken from the SEJS-NET system, one of the measurement systems working on the mining exploitation area, registering data on the surface. To process the data programs such as SPS and MatLab® had been used. Localization was carried out by the S-P method (input time difference of seismic waves S and P) of the localization of seismic events epicenters. The method enabled to determine epicenter of the tremor with the accuracy around 600m.
