Abstract: The paper reviews the results of research into the conditions and mechanisms of unique gas-dynamic phenomena, i.e. sudden dolomites and gas outbursts at the Internatsionalny mine which occur at depths of over 1,000 m. The research results have shown that almost all of these gas-dynamic phenomena can be classified as sudden rock and gas outbursts. They are different only in the fact that they stopped at various development stages of this phenomenon. It is established that the gasdynamic phenomena in the mine have a complex nature. Initially, brittle failure (a micro burst) takes place at the edge of the outburst-prone rock layer. The micro burst acts as the trigger for a sudden outburst of rock and gas. This specific feature of the phenomena calls for a special approach to their prediction in order to improve the reliability of the results. The performed research helped to develop a set of measures to prevent the gas-dynamic phenomena, which includes: (1) prediction of zones prone to sudden rock and gas outbursts; (2) ways of bringing the outburst-prone zones to a non-hazardous state; (3) safe modes of blasting operations when driving mine workings through the rock layers prone to sudden outbursts; (4) research into the development of safe technologies to drive mine workings using roadheaders. The results are presented of pilot testing complex measures for predicting and preventing sudden rock and gas outbursts when driving mine workings and the prospects for their practical application are described.
Keywords: Internatsionalny mine, gas-dynamic phenomena, sudden rock outbursts, sudden gas outbursts, prediction of gas hazards, ways to prevent gas-dynamic phenomena, blasting operations, advanced shot-firing
