Strength and deformation characteristics of high-accurate 3D printed physical models of honeycomb mine structures

The change in the stress–strain behavior of the modeled honeycomb mine structures is governed by the strength and elastic characteristics of equivalent materials as well as by the accuracy in manufacturing of the model elements. Application of new additive technologies in manufacturing of precise physical models using 3D printing and strong plastics as equivalent materials ensured purity of experiments and elimination of errors in selection of the material strength characteristics. The physical modeling data obtained using the advanced technologies made it possible to optimize stable parameters of design mine structures, to define subsequent modeling stages and to reduce the time of the labor-intensive experimentation. The experience gained in the advanced modeling and 3D printing allows manufacturing high-accurate physical models of frame and honeycomb mine structures and enables adjustment of the earlier testing data obtained in physical modeling using equivalent materials if necessary. The experimental research shows the promising nature of 3D modeling and FDM 3D printing accurate to 0.2 mm in geomechanical analysis in development of new mining technologies and their parameters.

Keywords: Honeycomb mine structures, physical modeling, stress–strain behavior, FDM printing, PLA, crate system of data acquisition.
