Rock pressure around the contour of horizontal mining works, has different values which are variable in time. Periodic rising of deformations on the supporting structure is corelated with gradual rising of rock pressure, which we will call primary pressure. As soon as the opening deformation stops, the primary pressure turns into secondary pressure. Both primary pressure and secondary pressure, show certain particularities which we will analyze in depth in this study. [ABSTRACT FROM AUTHOR] |
