ROJAS-SOLA, JOSÉ IGNACIO; MONTALVO-GIL, JUAN MANUEL  e  CASTRO-GARCIA, MIGUEL. 3D MODELING AND FUNCTIONAL ANALYSIS OF A HEADFRAME FOR MINERAL EXTRACTION. Dyna rev.fac.nac.minas [online]. 2013, vol.80, n.181, pp.118-125. ISSN 0012-7353.

This paper discusses in detail an example of the mining industrial heritage at the old mining district of Linares-La Carolina (Jaén, Spain), as is a masonry headframe crowned by a metal castle, used in the extraction of lead ore, specifically galena or lead sulfide. In particular, the modeling was performed using parametric software by means empirical techniques of each one of the elements of the set. Also, after obtaining the 3D model a functional analysis has been performed using techniques as Computer-Aided Engineering, based on stress analysis and analysis of displacements, ensuring that the highest stress concentrations occur in the middle and lower of the walls, that higher values are produced around the wall voids, and that the highest concentration of displacements in the masonry headframe are in the middle and at the top of the walls, and of the metal castle are in the cover straps.
