SRK: this is the effect of heavy rainfall

As the company responsible for removing the effects of the operation of the former mine, Spółka Restrukturownictwa Kopalń (SRK), is responsible for removing the effects of the former mine, the new hole is a reactivation of the sinkhole created in 2021. “We associate the situation with the intense rainfall that has taken place in recent days” – wrote the representatives of SRK, who went to the site in the afternoon.

“The event proves the rightness of the decision to exclude this part of the gardens from operation, due to the existing threat. We would like to remind you that this area is located in the line of the oxbow lake of Kozi Bród, i.e. the area where there is the greatest risk of sinkholes. This is confirmed by the research and results presented on February 15. – we read in the SRK communiqué.

The problem of sinkholes in Trzebinia

The post-mining damage is caused by the former “Siersza” hard coal mine, operating in this town since the mid-nineteenth century. In the years 1999-2001 the mine closed down. At the beginning, the exploitation was shallow, at a depth of 20-25 meters. Then the underground passages went lower and lower. The liquidators assumed that the voids left after exploitation would be filled with water. Over time, the water began to come closer and closer to the surface of the earth.

According to data provided in April by the Chief National Geologist, Piotr Dziadzia, in Trzebinia there are a total of 481 places at risk of sinkholes. 38 is located in close proximity to buildings – this buffer zone has a border of 20 meters.
