In Trzebinia, they will make boreholes through which they will inject a special substance that stabilizes the soil. This is the result of negotiations on securing the city against the formation of further sinkholes. The ground in Trzebinia has collapsed 25 times in recent years – most recently on Tuesday, January 10.

On Friday afternoon, the last negotiations of the Mine Restructuring Company with the contractors who will secure the land in Trzebinia ended.

As indicated by Spółka Restrukturownictwa Kopalń (SRK), the conclusion of negotiations with the contractors of the works “makes it possible to take action and immediately commence the works”. The company indicates that the contract has yet to be signed.

“The task consists in drilling boreholes in selected locations through which a special mixture will be injected to stabilize the ground. First, the works will be carried out in the area of ​​Górnicza Street, the cemetery and the adjacent car park, and then in the area of ​​the Family Allotment Garden ‘GAJ’ “- reported SRK.

25 sinkholes in Trzebinia

In recent years, the ground has collapsed in Trzebinia 25 times, of which four holes appeared in the built-up area, in the past protected against such an eventuality. The case became famouswhen in September a crater was formed as a result of a landslide in the Trzebinia cemetery engulfed about 40 graves.

After this incident, soil tests began in the city on 100 hectares of land in the area at risk of discontinuous deformations – as sinkholes are called – in the shallow mining areas of the former “Siersza” mine. It is the method of liquidation of this mine that is the probable cause of the formation of sinkholes that are dangerous for the inhabitants. The results of the research are to be known in mid-February.

The sinkholes arising in the commune 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.
