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.
