Seismic response to mining reduction in Mines in the Ostrava-Karviná Coal Basin
Holub, Karel ; Stodulková, S.
Based on long-term seismic monitoring, the influence of mining reduction to the level of seismic activity was investigated. Using data from the period of temporary mining reduction (July 1999) and a month before and after this period proved the obvious decrease of seismic activity.
Monitoring of the safe conditions of mine working
Holub, Karel ; Stodulková, S.
One of the characteristic parameters of the seismic regime is the course of cumulation and release of the deformation energy. Information concerning these changes have been usually presented in the form of Benioff diagram.
11 Years of the underground seismic network in the OKR
Kalenda, P. ; Holub, Karel
In 1988 the underground digital seismological network in the OKR was put in trial operation and since 1989 it has been in a routine operation. In the paper all changes in data interpretation approaches applied during its 11 years existence and futher possibilities in operation improvement of this monitoring system are discussed.
Present knowledge based on the seismic station Ostrava - Krásné Pole (OKC) operation
Holub, Karel ; Knejzlík, Jaromír ; Rušajová, Jana ; Růžek, B.
In the present contribution, description of software package for seismic data transmission and processing in OS Linux are given. Some examples of type analysis for several focal zones of mining induced seismic events and preliminary velocity characteristics are also presented.
Diagnostics of prevention effectiveness againts the rockbursts
Holub, Karel ; Stodulková, S.
As a part of the rockbursts preventative measures in mines in the Ostrava-Karviná Coal Basin, large scale torpedo blasting are carried out. Their efficiency evaluated according to the empirical formula diagnoses the successfulness of the performed prevention, the size of which is expressed as the ratio between the inner energy of the charge of explosives and the energy of the provoked seimic event.
