Problems and Ways to Prevent Gas-Dust Hazard during Working Operations

V.S. Zaburdayev, Dr. Sci. (Eng.), Lead Researcher, IPCON RAN, Moscow, Russia


Ensuring gas-dust safety at the working faces of methane abundant mines depends to a large extent on the taken measures and their connection with the input data characterizing coal seam. Amongst the latter are the gas content of coal, its strength and material composition, coal petrological differences, volatile matters yield, analytical moisture, physicomechanical and physicochemical properties of coal both in the massif and in the zone of destruction by the cutter-loader, intensity of methane release from the seam and the coal beaten in lava, the dust-forming ability of coal and rocks at the extraction of coal by the cutter-loader. Process solutions are proposed to reduce the intensity of methane release and dust formation at the working faces by using effective measures for degassing coal seams and their preliminary moistening in order to increase the moisture content of coal. The decisions are based on the knowledge of coals natural properties, their influence on the gas-dust situation in lavas.
