Popularno\u015b\u0107 piaskowca z D\u0142ugopola rozpocz\u0119\u0142a si\u0119 wraz z oddaniem do u\u017cytku odcinka trasy kolejowej mi\u0119dzy K\u0142odzkiem a Mi\u0119dzylesiem w 1875 roku \u2013 fragmentu planowanej linii z Wroc\u0142awia do Austrii.<\/strong>
\nZ jednej strony wykorzystywano ten materia\u0142 przy budowie tuneli, wiadukt\u00f3w, most\u00f3w i budynk\u00f3w stacji, z\u2008drugiej: kolej umo\u017cliwi\u0142a transport tego interesuj\u0105cego kamienia poza Ziemi\u0119 K\u0142odzk\u0105.<\/strong><\/p>\n

Wsp\u00f3\u0142czesna historia wydobycia rozpoczyna si\u0119 oko\u0142o roku 2000, kiedy firma Piasmar rozpocz\u0119\u0142a porz\u0105dkowanie z\u0142o\u017ca po\u2008poprzednich w\u0142a\u015bcicielach. Obecnie wydobycie odbywa si\u0119 metod\u0105 tradycyjn\u0105, bez u\u017cycia materia\u0142\u00f3w wybuchowych, a podzia\u0142 wi\u0119kszych bry\u0142 wykonywany jest przez klinowanie.<\/p>\n

Parametry techniczne pozwalaj\u0105 na praktycznie nieograniczone mo\u017cliwo\u015bci stosowania D\u0142ugopola zar\u00f3wno wewn\u0105trz, jak i\u2008na zewn\u0105trz. Obrabia si\u0119 go \u0142atwiej ni\u017c granit, ale du\u017co trudniej ni\u017c inne piaskowce. Do obr\u00f3bki u\u017cywa si\u0119 narz\u0119dzi do granitu, bo\u2008narz\u0119dzia do piaskowca szybko si\u0119 zamykaj\u0105 i przestaj\u0105 pracowa\u0107. Nie nadaje si\u0119 te\u017c do ostrzenia narz\u0119dzi diamentowych.<\/p>\n

 <\/p>\n

D\u0142ugopole ma barw\u0119 jasno\u017c\u00f3\u0142t\u0105, ze smugami o barwie \u017c\u00f3\u0142tej (obecno\u015b\u0107 limonitu) w postaci s\u0142oj\u00f3w, tzw. pier\u015bcieni Lieseganga. Bry\u0142y maj\u0105 intensywniejsze \u017c\u00f3\u0142te zabarwienie s\u0142oi przy kraw\u0119dzi bry\u0142y i coraz ja\u015bniejsze bli\u017cej jej \u015brodka. Dzi\u0119ki temu mo\u017cna uzyska\u0107 ciekawe efekty, uk\u0142adaj\u0105c obok siebie p\u0142yty uzyskiwane z rozkroju jednej bry\u0142y. W ostatnim czasie w z\u0142o\u017cu ods\u0142oni\u0119to r\u00f3wnie\u017c pok\u0142ad piaskowca w odcieniu jasno-szarym z ciemniejszymi smugami, zaburzeniami struktury w postaci tzw. laminek.<\/p>\n

 <\/p>\n

Ziarno piaskowca D\u0142ugopole jest drobne, lekko obtoczone i\u2008po\u0142\u0105czone spoiwem krzemionkowo-kwarcytowym. To powoduje, \u017ce materia\u0142 ma du\u017c\u0105 twardo\u015b\u0107, a jego wysoka odporno\u015b\u0107 na\u2008\u015bcieranie jest rzadko spotykana w\u015br\u00f3d \u017c\u00f3\u0142tych piaskowc\u00f3w \u2013 \u015bcieralno\u015b\u0107 na tarczy Boehmego jest niemal identyczna jak granitu strzegomskiego. Nadaje si\u0119 na wszystkie zastosowania, gdzie\u2002jest du\u017cy ruch: obiekty u\u017cyteczno\u015bci publicznej, intensywnie u\u017cytkowane schody, posadzki \u2013 wsz\u0119dzie tam b\u0119dzie si\u0119 wykazywa\u0142 trwa\u0142o\u015bci\u0105 i\u2002odporno\u015bci\u0105 tak\u0105 jak granit.<\/p>\n

 <\/p>\n

Materia\u0142 jest zwarty i nieporowaty \u2013 nie zdarza si\u0119 przesi\u0105kanie kleju nawet przez p\u0142ytki o grubo\u015bci 12 mm. Cechy te natomiast umo\u017cliwiaj\u0105 stosowanie chwytak\u00f3w podci\u015bnieniowych do transportu materia\u0142u. Ma te\u017c nisk\u0105 nasi\u0105kliwo\u015b\u0107, wi\u0119c dobrze sprawdzi si\u0119 na cokolikach, bo nie b\u0119dzie podci\u0105ga\u0142 wody z pod\u0142o\u017ca. P\u0142omieniowany ma w\u0142a\u015bciwo\u015bci antypo\u015blizgowe i mo\u017cna go stosowa\u0107 na basenach, posadzkach i schodach. Istotn\u0105 cech\u0105 D\u0142ugopola jest minimalna anizotropia (zmienno\u015b\u0107 parametr\u00f3w w zale\u017cno\u015bci od kierunku obr\u00f3bki). Umo\u017cliwia to ci\u0119cie i obr\u00f3bk\u0119 kamienia bez potrzeby zwracania szczeg\u00f3lnej uwagi na uk\u0142ad warstw, poniewa\u017c nie ma to wi\u0119kszego wp\u0142ywu na\u2008jego w\u0142asno\u015bci.<\/p>\n
