ES2666018A1 - PROCEDURE FOR THE FORMATION OF STONE BLOCKS IN QUARRY THROUGH HORIZONTAL EXTRACTION (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Process of forming stone blocks in the quarry itself, comprising the steps of forming a horizontal quarry bank at one end of a work zone; performing at least a first longitudinal vertical cut on said quarry bank at a distance from the edge of the quarry bank that corresponds to the width of the blocks to be formed, making a plurality of transversal vertical cuts on the quarry bench with a distance between said transverse vertical cuts corresponds to the length of the blocks to be formed, making a longitudinal horizontal cut on the quarry bench at a distance from the edge of the quarry bench that corresponds to the height of the blocks to be shaped and to extract the blocks of stone from the quarry. quarry conformed.

In this case, it is preferred that the longitudinal horizontal cut made has a depth that corresponds to at least the width of the quarry stone blocks to be formed.

Thus, finally, the stone blocks are formed from the cuts made on the quarry bench. Subsequently, in step e), said shaped blocks are extracted from the work area.

In a first embodiment, the steps from b) to e) are repeated for each quarry bank formed in stage a) throughout the extension of the work area. In other words, in the work area conformed to a certain level of extraction, the removal of the stone blocks formed with the rocky material of a quarry bank entails returning to stage a), that is, a new new quarry bank, on which, the actions of the stages from b) to e) are repeated for the formation of new quarry blocks; and thus, the steps from b) to e) are repeated successively until they have formed blocks of stone with all the rocky material of said work area, by then, to explode a new level of lower extraction of the quarry, the which begins with the application of the actions of sub-stage a.2) or a.3) for the formation of the horizontal quarry bank at said lower exploitation level.

In a second embodiment, step b), additionally, includes making a plurality of second longitudinal vertical cuts, parallel to the first longitudinal vertical cut, over the entire length of the work area, where, the first and second longitudinal vertical cuts a perform distance from each other in correspondence with the width of the quarry stone blocks to be shaped. In other words, a plurality of longitudinal vertical cuts are made, spaced apart from each other according to the width of the stone blocks to be formed, distributed throughout the length of the work area.

On the other hand, in this second embodiment, additionally, the vertical transversal cuts to be made in step c) extend from the edge of the quarry bench formed in step a) to the entire extension of the work area.

Thus, the entire extension of the work area of the extraction level in question is divided by a plurality of longitudinal vertical cuts and cross-sectional vertical cuts, defining the lateral faces of the quarry stone blocks to be formed, the latter, staying united to the rocky massif only by its bases.

Subsequently, in this second embodiment, steps d) and e) are carried out, which, as mentioned, involves the formation of a new quarry bank at the end of the work area, over which, they are repeated the actions of stages d) and e) for the formation of new quarry blocks; and thus, said stages d) and e) are repeated successively until they have formed blocks of stone with all the rocky material of the work area, by then, to start exploiting a new level of lower extraction of the quarry, which, starts with the application of the actions of sub-stage a.2) or a.3) for the formation of the horizontal quarry bank at said lower exploitation level.

In both embodiments, the quarried stone blocks removed are stored, being ready for commercialization as required.

It can be understood that the shaping and extraction of the stone blocks is carried out entirely directly from the rocky massif of the quarry, where, the horizontal cut and the vertical cuts made determine the final measurements of the shaped stone blocks. Therefore, it is important that these cuts are made properly squared together and correctly leveled, as well as, at the distances previously established.

Therefore, it is preferred that said cuts be made with sawing means, to ensure accuracy in making the cuts.

Likewise, to guarantee the accuracy of the dimensions of the stone blocks to be formed, preferably, the cuts made in stages b) and c) are previously bounded and marked on the quarry bank formed in stage a) or over the entire length of the work area, according to the corresponding implementation.

The application of the procedure generates very little amount of sterile or waste of the rocky material, which can be deposited in surrounding areas where the exploitation that has been deteriorated previously is carried out, helping to restore said affected areas.
