Nr 4/2016 (528) Bogdan CIANCIARA, Zbigniew ISAKOW, Kazimierz SICIŃSKI, Aleksander CIANCIARA Możliwości predykcji wstrząsów na podstawie analizy zjawisk maksymalnych emisji sejsmicznej w systemie INGEO Predykcja czasu wystąpienia wstrząsów w systemie INGEO oparta jest na analizie emisji sejsmicznej rejestrowanej w systemie sejsmoakustycznym. Sygnały emisji są generowane pękaniem górotworu wywołanym eksploatacją. Emisja taka charakteryzuje się dużą aktywnością […]
Read MoreNr 3/2016 (528) TOMASZ MOLENDA, SŁAWOMIR CHMIELARZ Galvanic separation of analogue signals The article deals with the issues of galvanic separation of analogue circuits and methods to perform it. The authors described capacitive, inductive and optical couplings, separation with the use of processing as well as non-linearity correction of optoelectronic materials characteristics. The available solutions […]

The following characteristics were determined: static characteristics of the load angle depending on […]
Read MoreNr 1/2016 (528) ARTUR DYLONG Monitoring and prediction of methane emission in the longwall and possibilities to control the longwall system Monitoring systems which are applied in mining today are based on solutions developed in 1990s. The knowledge about methane emission from rock mass and goafs, occurring during the longwall-based coal cutting process, has been […]
