Lassing talc was discovered in 1891 by the local landowner, Krennmoar, during construction work. He secured the mining rights. In 1901, the firm of
Bischetsrieder & Gielow began underground extraction. In the mid-1920s, mining was suspended for a few years due to the bankruptcy of the owner. In

On 17 July 1998 the roof of an illegal level collapsed. Water poured in and caused a mudslide to break into the mine. At the surface this became evident as a house in the village of Moos, under which the mine was located, slowly began to collapse and sink into the sinkhole being formed. The crater

Initially there was telephone contact to the 24-year-old miner, but then he was cut off. A rescue party of nine miners and a geologist went that same day into the mine. When, around 10 p.m. the second mudslide caused the mine to implode, the "horror in slow motion" began. The crater grew larger,

Then the "Miracle of
Lassing" occurred. The first miner to be buried, Georg Hainzl, was rescued after ten days and was found in surprisingly good health. His rescue was achieved by a German company that had previously worked with OMV and had a suitable drill rig available that, unlike the OMV

Austria's fire chief,

The company was alleged to have tunnelled illegally under built-up areas and too close to the surface. As a result, there were no up to date plans so that the rescue work often had to rely purely on the oral statements of miners in the wake of the disaster.

Soon it was reported that there was no way of saving the eleven victims. An order of special drills from
Germany was cancelled by the management. Rescue efforts were sluggish. Outside help was not wanted. In charge of drilling was the technician,

Austria the lessons from Lassing led to far-reaching changes in mining, rescue technology and information policy. There followed legal reforms in 1999, 2002 and 2004. The anachronistic seeming Leoben Local Mining Office

work was used to extract the talc, using lean concrete. The South Field was opened up via the 204-metre-deep Renée Shaft, sunk in 1978-80. From the shaft, the talc deposit was accessed on ten levels.

The rescue operations were continued under pressure from the media. According to experts, who assessed there was no chance of survival, they should have called rescue attempts off earlier.

In the face of the publicity the ten miners were sent back into the mine to rescue Hainzl. According to internal sources they should have secured the mine from further collapse first.

Because there was no organized psychological health care at that time for victims and their families, the role was taken on by the local parish priest. Only the governor,
