pilíř porubní stěny Explanation: nejsem na to žádný odborník, ale asi to bude toto: Page 1 Acta Montanistica Slovaca Ročník 3 (1998), 1, 89-91 Stabilita uhelného pilíře s ohledem na dobývanou mocnost sloje či lávky v protiotřesovém boji se zřetelem k důlním podmínkám OKR Stanislav Bukovanský 1 Solid Coal Stability with Regards to Seam Thickness or Bench mined in Anti-Bump Fight in OKR Mining Conditions In the paper the problem of working unit stability, showing a limit state of a rock tension with the Mohr envelope known from a theory of failure, is described. It is obvious that a load of building units in mountain massives can be expressed easily either by simple or multiaxial compressions, and then, on the basis of individual states characteristics, individual conditions of stability can be observed. So we may understand that such building units can be broken even in case of a certain discharge, i.e. lowering of one of main tensions of both of them as well. Combined methods of discharge and surchage can be used too. Another reactive power of an enormous value is caused by pre-fault then. In the OKR district it means even 10% of the seam thickness with common conditions (e.g. saddle seams). An area of a contact between a seam, original rocks and seam thickness should be taken into consideration as serious conditions of rock bumps origin. If this contact area is wavy of the seam thickness is small (possibly both conditions are valid), there will be no risk of any rock bump. Key words: Coal Pillar Stability, Anti-Bump Fight. Stabilita uhelného pilíře s ohledem na dobývanou mocnost sloje či lávky Uvažujeme-li na uhelných dolech ostravsko-karvinského revíru (OKR) pro zjednodušení v oblasti líce výrubu (tj. předku chodby nebo pilíře porubní stěny) pouze rovinnou napjatost, vzhledem k tomu, že problém je řešen pouze pro oblast poblíže díla, je možno s výhodou charakterizovat mezní stav napjatosti hornin Mohrovou obálkou, známou z teorie porušení. Obdobné východiská sú u mnohých autorov (Bukovanský, 1997; Sasvári a Ďurove, 1996). Pak lze snadno zobrazit zatížení stavebních jednotek horského masivu prostým tlakem (případ A) a víceosým tlakem (případ B) dle schematu na obr. 1. http://webcache.googleusercontent.com/search?q=cache:gnauK_8... -------------------------------------------------- Note added at 7 min (2014-07-28 15:25:59 GMT) -------------------------------------------------- nebo jen pilíř porubu https://www.google.cz/search?q=pilíře porubu&ie=utf-8&oe=utf... |
