The problems of geodynamic safety assurance in mining are common for many countries with developed mining industries. Considerable results have been achieved in Russia in solving rockburst problem, yet in the last decades this problem is transforming into man-triggered seismicity problem. Induced earthquakes in areas where mines had been flooded, seismic activity in previously safe regions, re-activation of tectonic faults, violent man-triggered earthquakes in open pit operations have been registered. As a matter ...

The hazard of tecnogenous earthquakes caused by mining of mineral deposits is increased if they occur at economically developed regions with ecologically dangerous objects. A deep coal mine of the Sinvay deposite in China is an example when seismicity due to mining was an important factor influencing both the mining conditions and ecological environment. At a more than 1000m mining depth the power of rock bursts rose to 107 J and they manifested themselves as minor earthquakes on the earth surface. The increasing ...

One of the reasons for spontaneous combustion of coal waste dumps is the air intake into the body of a dump. Despite the measures taken to isolate the bases and dump slopes, spontaneous combustion of dumps occur in many countries around the world. That breeds a hypothesis that spontaneous combustion process is facilitated by placement of a dump in the geodynamically active zone of the earth's crust. In geodynamically active zone, due to its high permeability, the interaction of the dumps with environment occurs. P...
