Study on the Stress Concentration Law and Impacting Disasters in Roadway of Some Mine

摘要

The impact disasters of rock burst and pressure bump are common problems of underground construction and deep mining. This paper selected the typical mine based on the work of field crustal stress measurement, indoor rock mechanical experiment, parameter calculation, numerical analysis and field disaster investigation, etc,. Deeply analysed the basic types and potential laws of possible impact disaster after a mine's main tunnel excavation based on the study idea of experimental rock mechanics and computational rock mechanics co-ordination and additional verification.
