The Estimation of a Possibility of Outburst Origin in Long Mine Workings

Abstract

Problems of rock and gas outbursts are still topical. According to [1] and other sources, this hazard is very serious in many countries, for example in China, Ukraine, in the area of Kemerovo (Russia), Poland.In the framework of solving the grant task No. GAČR 105/05/013, VŠB-TU Ostrava 2005, we focused our attention to the methods of forecasting the mentioned phenomenon too. From the detailed analysis of forecasting methods in the Czech Republic as well as abroad it follows that the existing methods do not express a possibility of outburst origin with sufficient reliability.
