    Rozwarstwienie stropu w wyniku eksploatacji systemem komorowo-filarowym z ugięciem stropu złoża rud miedzi w LGOM
    (Wydawnictwa AGH, 2005) Wosz, Ryszard Józef
    The article is continuation of the research works concerning the principal and direct roof strata deflection above the deposit mined by means of the chamber-pillar system with roof deflection in the exploitation conditions of the copper deposits in LGOM. A model of the roof deflection and the solutions of the equations of the beam’s axis deflection have been shown in the earlier papers. In this paper has presented the functions of the deflection with two points: A and B of start of stratification the Basic and Direct Roof. The Point A has located in the area over the seam of deposit, and the Point B — over the pillars (Fig. 1). The new constants of equations have been calculated. The new lines describing deflection of the Roof Beams have been presented in the figure 2 and 3.
