Areas at risk of sinkholes in Trzebinia (Lesser Poland Voivodeship) will be treated, representatives of the Mine Restructuring Company, which commissioned soil testing in this town, announced on Wednesday. Due to the very frequent cases of land collapse, scientists have selected the places most at risk of further holes. These include a cemetery and a stadium.

On Wednesday after 4 p.m., representatives of the Mine Restructuring Company presented the results of soil tests in Trzebinia, where the ground has collapsed many times in recent months. Sinkholes in this town are a serious problem, because over the course of about 1.5 years, such holes appeared at least 25 times.

The largest of the breaches was created in September at the Trzebinia cemetery, absorbing 40 tombstones. Only since Christmas, seven sinkholes have formed in the city – so far for the last time February 3 at the stadium of the UKS Górnik Siersza club.

On Wednesday, February 15, the announced meeting of municipal officials and residents of Trzebinia with representatives of the Company for the Restructuring of Mine (SRK) took place. During it, the conclusions of five months of soil research, which covered 80 hectares of land, were presented.

The information provided shows that the valley of Kozi Brod, the southern part of the cemetery and the stadium have been selected as endangered. These areas are to be “treated” by SRK. Importantly, the research results show that no block of flats is at risk of sinkholes.

– We will gradually protect this area through specialist drilling and injections as well as backfilling the excavations in the cemetery, the area of ​​Górnicza Street, and the UKS Górnik Siersza Stadium. We will still explore other areas around Sportowa Street – declared Marcin Węglarz, deputy director of the SRK SA branch of KWK CL during the meeting.

The representative of the company added that the excavations do not cover the Gaj estate. This means that this place is not at risk of sinkholes. – We have planned further drillings in that area to additionally confirm that these sinkholes will not occur there – added Węglarz.

Zadliska in Trzebinia

The sinkholes in Trzebinia are post-mining damage 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.

Soil tests were ordered in September. Without waiting for the results to be presented by the municipal authorities decided to close Górnicza Street, where there are sinkholes. In early February, the residents themselves created an interactive map of sinkholes in Trzebinia, which can be found on the Internet.
