This event transpired in test roadway 16b in seam 407/3 at the 850 level following blasting work. The mine staff immediately launched a rescue effort. 10 mine employees were in the area at risk. No one was hurt and all the employees safely vacated the region at risk.
In this rescue effort the rescue workers isolated the region at risk from the rest of the mine. Around 3 a.m. on Monday the rescue workers completed isolating the underground mining pit, which they sealed off with a water anti-explosive plug. After the elapse of 12 hours they will begin work to restore ventilation to the remaining portion of the mining pit, which will take two days.
Currently, the District Mining Office in Gliwice is investigating the causes and circumstances of this event. A mine risk commission including experts will be formed in the mine to determine how to proceed in this region.
