Abstract

The issues of obtaining and investigating composites consisting of coal and rock solid particles, gases (methane, hydrogen) and moisture, as well as approaches to mechanisms initiating catastrophic dynamic phenomena in mining are discussed. On the samples of different materials (coal, limestone, graphite, etc.) using the developed test bench, the dependences of physico-mechanical properties of cores on pressure are established. For longflame coal of various size, the features are shown for changing the temperature of briquette mass in increasing pressure up to 200 MPa. The composites imitating natural coal and other rocks are created.
