Four miners have been injured seriously so far. As per source there were around 312 workers under the surface at the time of blast. They were inside the Raspadskaya mine near Mezhdurechensk. The rescue operations are on. Many of the mines in the country are of very poor standards of safety and the standards have not been updated since fall of communism.
