I cannot find any sources showing notability. Does anyone know of sources or an alternate name this would be found under? ping Piotrus for possible information.   //  Timothy ::  talk  22:41, 18 November 2020 (UTC) reply

@ TimothyBlue: I expect such objects too be notable. Pl wiki has (as further reading I cannot verify) a book "Jerzy Jaros: Słownik historyczny kopalń węgla na ziemiach polskich. Katowice: Śląski Instytut Naukowy, 1984. ISBN 83-00-00648-6." and links to two pages describing the history of that coal mine ( [1] and [2]) maintained by a reliable organization, pl:Stowarzyszenie Inżynierów i Techników Górnictwa. Here are some Polish-language academic sources about this object: [3], [4], [5] (this one has an English abstract), [6], [7], [8], [9]... I think that's a keeper. -- _{Piotr Konieczny aka Prokonsul Piotrus| reply here} 14:42, 19 November 2020 (UTC) reply
