Tilas stoll in English

 

Be careful when entering the mine and do not leave the footbridge, it is not a solid bottom next to the bridge but only a plank covering, as you see on the profile map, picture 5, it is from the bridge approx: 50 meters down to the bottom of the mine.

Stollen is named after the mining councillor Daniel Tilas, b 1712, d 1772.

Daniel Tilas was awarded many titles, Mining Councillor, National Heraldry, Baron, Genealogist, Titular Governor and Knight of the Royal Order of the Polar Star. Over time, Tilas became a prominent man with many assignments, among others, in 1737 he participated in the design of a canal building in Finland, in 1738 he was at the request of the Mining College to Russia to study the mines around Lake Onega, in 1741-45 he was part of the Border Commission’s work to determine the border with Norway, in 1761 he proposed to the ”Kongs Collegiet” to approve the construction of a sawmill for Persberg’s mines in the Yngshytteälv river. In 1768 he had the honour of being a cicerone to Crown Prince Gustaf on his trip to the various mines in Bergslagen, on 25 September the travellers arrived at Persberg’s mining field where the Crown Prince was given a demonstration of the, at that time, unique ”Fire and the Air Machine”.

 

Why the ceiling height is so high at the beginning of the stollen has been wondered, the reason being that after a few years of work, in 1769, the advantages of lowering the sole of the stoll to the highest level of Lake Yngen were realized. Since the lifting was done by hand and horse-drawn winds, before hydropower was available, every meter of reduced lifting height was valuable. On old maps you can see that the stollen was used for shipping out of the mine, it was of course also used to divert the water pumped up from the mine out to the lake.

 

Harald Carlborg writes in ”Persbergs Malmtrakt” the following about the financing of the work on the stollen.

”Tila’s chair in Högberget must have been the first joint work carried out with the funds of the mining fund fund, for as early as 1760 it was decided to push it forward in this way one fathom a year, after the funds obtained by the sale on joint account of a newly discovered deposit, Rudbeck’s Gang, had been spent. In fact, it was hoped that in time >> the mining fund would be so large that it would be able to maintain the stollen itself and sell the exposed ore passages on a purely purchase as a stoll<<. However, unfortunately, Tila’s stoll as a business speculation turned out to be a complete failure.” ( 1 fathom= 1.78m. )

 

Here is information about Tila’s stoll taken from ”Extract of the Relations on Filipstad’s Bergslags Mines from the Oldest Times Until the Year 1880.

 

  • The 1760 Commission proposed to include a stoll, the so-called Tila’s stoll, for the investigation of the Högberget ore field.

 

  • 1762: For the planning of the land, no miners were needed, but ordinary workers were expensively hired, because Filipstad was built after the fire: ”Therefore uphound”.

 

  • 1767: A rock pallet was broken away in front of the munlock to the stolle, then work began with miners from Sala.

 

  • 1768: Red halibut makes the work difficult. Sole length 4 fathoms. (7.1m)

 

  • 1769: The sole lowered to the highest level of Yngen, thus lowered 2 ells. (1.18m)

 

  • 1772: Harald Carlborg has made a note that shoplifting of cooking wood occurred at Tila’s stoll.

 

 

In his diary of Crown Prince Gustav’s trip to Bergslagen in 1768, D Tilas gives the following description of the function of Fire and the Air Machine.

 

>>The drive is caused by a boiling watt boiler, from which the steam through a tube rises into a perpendiculaire cylinder and drives up a piston or lid, which falls down again when the cold water is released… and with the same Piston the Government is combined, as by means of the rising and falling of the Piston, the Wattu Art and the Pumps.

The upward motion of the jug is thus effected by the steam, and probably also by the weight of the pump-rods, while its downward motion is caused by the atmospheric pressure of the condensation of the steam>>.
