Soil testing at the cemetery and allotment gardens in Trzebinia with the use of georadar will start soon. These are places at risk of sinkholes. The survey, which is to show the structure of the soil, was supposed to start on Tuesday, but it was postponed to the next few days due to rain.

The area of ​​the cemetery and the northern part of the allotment gardens in Trzebinia (Małopolskie Province) will be surveyed with a ground-penetrating radar.

As TVN24 reporter Jerzy Korczyński reported, originally the research – which would cover a length of about three kilometers – was supposed to start on Monday. However, it was moved to Tuesday. And on Tuesday it was decided that due to unfavorable weather, they will be moved to the next few days. They will most likely start on Thursday.

The planned research is to help determine the structure of the soil in connection with the sinkholes appearing in Trzebinia. According to Spółka Restrukturownictwa Kopalń (SRK), the tests will be carried out using one of the three georadars available in Poland.

Research in the area of ​​sinkholes in Trzebinia

– The area of ​​the cemetery has been explored so far in the area of ​​the sinkhole and on large alleys. Now it will be examined in its entirety, also between the alleys, so that everything is verified to have a picture of the whole – informed the spokesman of SRK Mariusz Tomalik.

Georadar will also appear on the northern part of the allotment gardens, which is accessible to residents and has not been explored before, where, according to the findings, no mining was carried out. – The southern part of the gardens is closed, but the northern one is not, so we want to verify in detail whether it is safe – added Tomalik.

On June 20, SRK informed that the areas of, among others, primary school no. 5 at ul. Jana III Sobieski and the EDISON private primary school at ul. Grunwaldzka – microgravimetric tests were carried out there in April and May.

Leakage of soil stabilizing substance. VIEP is waiting for the test results

As TVN24 reporter Jerzy Korczyński found out, this week the results of the tests of the Provincial Inspectorate for Environmental Protection on the Kozi Bród River should be known, into which a soil stabilizing substance leaked on June 19. The first findings of the VIEP indicated that there was no contamination of the water.

The substance that got into Kozi Brod is a special mixture of cement, power plant by-products and water. Since March, voids and loosening of the ground have been filled with it in places indicated as at risk of sinkholes. This is to prevent further holes from forming.

This mix is ​​stored in large silos and pumped below the surface. As reported by Spółka Restrukturownictwa Kopalń after the leak, the failure occurred during the injection of voids near the Gaj housing estate.

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.
