Abstract
Stojak podatny (10) do kopalni zawiera pierwsza rure metalowa biegnaca od spagu kopalnianego (34) majaca czesc pierwsza majaca pierwsza srednice zewnetrzna i czesc druga majaca druga srednice zewnetrzna. Stojak zawiera druga rure metalowa, która jest umieszczona wokól czesci pierwszej i biegnie w kierunku stropu. Gdy druga rura przyjmuje obciazenie stropu kopalnianego, to czesc druga odksztalca druga rure i rozszerza druga rure, stawiajac opór obciazeniu stropu kopalnianego. Przedmiotem zgloszenia jest równiez sposób podpierania stropu kopalnianego, sposób budowania kopalnianego stojaka podatnego.
