Inventia se refera la o metoda de exploatare pentru minereuri descendente în subetaje scurte, aplicata la minereu sub forma de lentile de grosime mica si înclinare mare. Metoda consta aceea ca, între o perna ca de rambleu si mineralizatia geometrizata, se desfasoara o retea plana de toroane de cablu si plasa de sîrma, care, pe masura exploatarii, urmareste frontul de lucru, dispunîndu-se, sub actiunea pernei de rambleu, dupa traiectoria unui fir greu, suspendat în doua puncte necoliniare.The invention relates to an exploitation method for descending ores in short substrates, applied to the ore in the form of small thickness lenses and high inclination. The method consists in that, between a pillow and a geometrical mineralization, there is a wired network of cable strands and wire mesh, which, as a result of exploitation, follows the working front and, under the action of the cushion cushion, after the trajectory of a heavy thread, suspended at two noncolar points.
