When designing the supports of preparatory and capital mine workings, a number of complex problems arise, which are associated with the need to calculate the supports for the action of sufficiently large static loads occurring at great depths and for the dynamic impact of loads from blasting operations and seismic vibrations of the earth's crust. Currently, the most successful and more complete calculations of supports for the action of static loads, compared with calculations for the actions of dynamic and seismic. But, despite this, it is impossible today to claim the creation of perfect methods for calculating supports for the action of even static loads. In such conditions, the issues of assessment, forecasting and ensuring the stability of mine workings are key in the rapidly developing, in recent years, rock mechanics and mining practice.
