Another sinkhole appeared in Trzebinia (Małopolskie Voivodeship). The hole in the ground was created in the training court in the Siersza estate, in an area considered potentially endangered. The sinkhole area has been fenced off. Noone hurt.

The incident happened on Friday (June 2) evening. As the mayor of Trzebinia Jarosław Okoczuk informed, the inhabitants of the estate reported another sinkhole after 7 pm. It was notified to Spółka Restrukturownictwa Kopalń, which is responsible for post-mining damage caused by the former “Siersza” mine.

As the mayor said, a hole in the ground with a diameter and depth of about four meters was created in the training court at Górnicza Street. The area had previously been excluded from use as potentially at risk of sinkholes, but the local club, at its own risk, was still conducting sports activities on the adjacent courts on Friday.

– The sinkhole area has been taped and fenced to prevent access by third parties. This is an area that has been indicated as potentially endangered, where sinkholes have already occurred in the past – noted the mayor.

The “Siersza” mine ceased operation in 1999-2001, and its liquidators assumed that the voids left after mining would be filled with water. Over time, the water began to come closer and closer to the surface of the earth. The phenomenon of sinkhole formation in Trzebinia intensified in 2021. Previously, for 20 years after the liquidation of the mine, it occurred sporadically.

According to experts, the deformations are caused by water constantly flowing into the post-mining excavations and the type of soil – there are sands, gravels and clays. Shallow exploitation, conducted here in the 19th century, also contributes to the formation of sinkholes. The sinkholes in the Małopolska commune became famous in September 2022, when the earth absorbed several dozen graves in the cemetery parish.

They pump water out of the ground. “A milestone in an unequal fight”

On Monday (May 29) in Trzebinia, the Mining Restructuring Company launched two special pumpswhose task is to maintain the underground water table at a stable level. According to experts, maintaining the level of the water table should be an effective method of counteracting the formation of sinkholes.

“The launch of pumps pumping underground water from Siersza is undoubtedly a milestone in the unequal fight against sinkholes, which we have been fighting for almost two years. Do they give us a 100% guarantee that sinkholes will not appear? No, there is no such guarantee, probably more than once will appear in the most endangered areas, although everything indicates that they should appear less often and on a smaller scale” – the mayor of Trzebinia commented on social media on Friday.
