METHODOLOGY OF THE ASSESSMENT OF SEISMIC SAFETY OF EXPLOSIONS EXECUTED IN UNDERGROUND MINES NEAR HEAPSTEDS

Questions of ensuring seismic safety of the heapsteds, when explosive works are conducting on underground mines at early development stages of a mineral deposit, are considered. Influence of the surface seismic waves propagating on mine workings as a result of seismic action of explosion is analyzed. The possible reasons of catastrophic consequences as a result of weak seismic influences are discussed. The new criterion of an assessment of seismic safety of the protected objects is offered. This criterion corresponds to achievement of level of a response of system soil – a land construction to the level of seismic impact of explosive works.

Keywords
