METHOD FOR PRODUCING A STRUCTURE HAVING COHESION BY MEANS OF A MATERIAL COMPRISING NON-COHERENT SOLID PARTICLES ABSTRACT OF THE DISCLOSURE There is constructed around pillars of a mine chamber on the ground a rectangular enclosure which is defined by superimposed layers of U-section elements. The concavity of the latter faces inwardly of the enclo- sure. A pulverulent material is poured by a hydraulic filling method into the enclosure. This pulverent material preferably comprises light fine ash having hydraulic properties. Owing to the reinforcements embedded in the mass, the structure initially bahaves as stabilized earth, but, in the end, the material sets and becomes coherent so that finally the structure has a lean concrete character.
