The Influence Of Coal Physical And Mechanical Properties And Mining Energy Consumption Factor On Airborne Respirable Dust Level, Antoni Koziel, Malgorzata Malec, Ewa Wardas

U.S. Mine Ventilation Symposium

The fact that there are not any explicitly defined relationships describing the influence of physical and mechanical properties of coal and of energy consumption factor on dust level prompted Polish and American investigators to carry out a joint research project within the framework of the U.S.- Poland Maria Sklodowska-Curie Joint Fund II. The paper presents methods used to perform tests under laboratory conditions at the Pittsburgh Research Laboratory as well as under real conditions in the course of coal cutting in polish coal mines. Measuring systems and results of the tests are described. The analysis carried out has provided ...
