摘要
Granite and kaolin clay are chief geological reserves of the Strzegom municipality and both are currently mined commercially, while basalt used to be mined in the past. An abandoned basalt quarry allows us to see the full lifecycle of a mine, particularly its last stages. The basalt quarry in Strzegom is situated on a plot with an area of 5.1434 ha. Commercial basalt mining on the Wide Mt. in Strzegom began in the 19th century. The mine was shut down in 1981 after the extraction of about 86% of documented resources. In 1986, due to heavy exhaustion of the granite bedrock and the creation of an area of protected landscape, the Chief National Geologist revoked the decision from 1964, thus ruling out any possibility of commercial mining in that area. The last stages of the mine's life do not involve human involvement. The area is undergoing mine reclamation through ecological succession only. Currently, the pit is filled with water, partially overgrown with reed, with sharp cliff sides, going all the way down into the water. Leaving the mine to heal naturally has given great environmental results. Geological formations in the area have provided habitat for rock plants and heat-loving plants. Lack of human intervention in the profile of the pit had no negative effect on the site. A landscape analysis of the area has confirmed that it is of high ecological value. Therefore, the quany meets all the requirements to be included on the list of historical quarries. We have to make sure that the last stage in the life of this mine does not become less attractive and important for the economy than in the days when it was still operational.
