Hauzeur-Shaft

ODELIN (1787, 1st crack) calls it "Puits de la chaire à prescher", translated roughly "preacher's chair shaft" or "pulpit shaft". The shaft is located slightly to the right of the adit and, when it was discovered in 1994, it was obstructed by timber lining (door jambs made of logs and boarding) in the roadway. Most of the shaft is in the valley fill, which begins at about 2.50 m above the gallery floor. At the end of January 1995, the timber lining collapsed as a result of heavy rainfall. The collapse funnel was dredged in May 1995 and a new shaft tube was constructed, the lowest section of which was made of concrete and the upper section of which was made of bolted rough carpentry. The current shaft cross-section is 3.20 x 3.20 m, and the depth to the gallery floor is 9.40 m. In November 1995, the shaft house was finally erected above the new shaft. In 1995, the shaft was dedicated to the first operator who successfully ran the copper mine from 1723 to 1730, and was given the name "HAUZEUR-SCHACHT".
