KOMAG - Maszyny Górnicze

A scientific-and-technical quarterly, published by the KOMAG Institute of Mining Technology for over 30 years, is a magazine which presents scientific, research-and-development and implementation projects in the domain of mining mechanization, especially as regards the following:

underground mechanization systems in mines,
mechanical processing,
impact of mechanization systems on the environment,
man-machine ergonomic relationships,
as well as projects on the environmental protection, safety, work ergonomics, certification and standardization.

Articles written by scientists from institutes and universities, employees from research-and-development centres as well as mine technical personnel and manufacturers of machines are presented in the quarterly.
