Opat som natrafil na malu zaujimavost - najhlbsie povrchove miesto v Europe. Je nim povrchova bana v Nemecku, ktorej dno lezi 293 metrov pod urovnou hladiny mora. Bana je v prevadzke, a planuje sa jej rozsirenie na trojnasobok jej sucasnej rozlohy.
Nechyba veru az tak prilis vela do rekordu ktory drzi Mrtve more...

Tak to je sila. Na Google Maps som napocital 12 velkych rypadiel - takychto drobcekov.

Ano, maju tam riadne stroje - Bagger 288, Bagger 293...
Riadny obor:
Bagger 293 is 96 metres (314.9 feet) tall (highest terrestrial vehicle, size shared with Bagger 288). It is 225 metres (738.2 feet) long (same as Bagger 287), weighs 14,200 tons (31.3 million lb), and requires five people to operate. The bucket-wheel itself is over 70 feet in diameter with 20 buckets, each of which can hold over 15 cubic metres of material.
It can move 240,000 cubic metres (8.510 million cubic feet) of earth per day (same as Bagger 288).

S tou APOD fotkou je to tiez zaujimave - to bol prave Bagger 288:

By February 2001, the excavator had completely exposed the coal source at the Tagebau Hambach mine and was no longer needed there. In three weeks it made a 22 kilometer (14 mile) trip to the Tagebau Garzweiler, traveling across Autobahn 61, the river Erft, a railroad line, and several roads. The move cost nearly 150 million German marks and required a team of seventy workers. Rivers were crossed by placing large steel pipes for the water to flow through and providing a smooth surface over the pipes with rocks and gravel. Special grass was seeded to smooth its passage over valuable terrain. Moving Bagger 288 in one piece was more economical than disassembling the excavator and moving it piece by piece.

Pozeral som na Google Maps, ze tam na okoli je viac takych bani (a v kazdej zopar "drobcekov"). Poriadne to tam rozryli... a to som si myslel, ze najvacsi demolatori terenu su Cinania, ale Nemci zda sa tiez nezaostavaju.
Ta druha bana, Tagebau Garzweiler, ma na Wikipedii este spektakularnejsiu panoramaticku fotku (treba pozriet v plnom rozliseni a skrolovat).

Ta panorama je velmi pekna, pekne vidno ako postupne pri rypani klesaju.
Veru riadne si toNemci rozkopali, tiez som bol prekvapeny, ze 80 milionova krajina ma priestor na taketo plochy. A este kvoli nekvalitnemu hnedemu uhliu...

Ale s rypanim podla mna drzia prim Rusi - ten kontrast panelakov hned vedla 550 metrov hlbokej jamy s priemerom 1200 metrov, nad ktorou maju zakaz lietat helikoptery kvoli havariam, ked ich vetry vcucli dole, tak tomu hovorim zasah do krajiny..

Ty nemecke povrchove doly jsou sice velke, jenze mrknete na mapu Ceska a kouknete od Teplic az k Sokolovu. To je defakto s prestavkami jeden povrchovy dul za druhym.
V relaci k velikosti nasi zeme to je o dost neco jine, nez ta sranda v Nemecku.
Poradne velke rypadlo se da zkouknout par metru od dalnice nekde u Lipska (Leipzig) - muzu vam rict, ze cloveku dojde ta velikost, az kdyz je tesne vedle toho a autem to objizdi par minut...

Shafo mas pravdu, ved aj co sa tyka outputu hnedeho uhlia tak Cechy su svetovou mocnostou - aj ked vzhladom k rozlohe to nutne znamena devastaciu...

K tomu baggru 288 - zaujimave je, ze na plnu prevadzku mu staci cca 16.5 MW elektrickeho vykonu (napajany je externe)..
Zaujimave je to ked to clovek porovna s najvykonnejsim motorom na svete: Wärtsilä, ktory ma vykon 80 MW (a spotrebu mimochodom skoro 14 tisic litrov nafty za hodinu, a len sam vazi vyse 2300 ton).
Ten motor by utiahol prevadzku skoro piatich takych monstier..

No dost brutus, kvoli par supom nezoxidovanych rastlin...
Tie fotky mi pripominaju ekologicky znicenu krajinu Lorida z detskeho sci-fi filmu z roku 1985 Treti Sarkan na motivy romanov Jozefa Zarnaya..
