    The Ziordia quarry has an orography formed by limestone rock, with steep slopes as a result of quarrying, and potentially unstable large blocks. The company CRS Ingenier\u00eda contacted Bianchini Ingeniero to analyse the situation and possible solutions, and subsequently the company Inacc\u00e9s Geot\u00e8cnica Vertical also intervened. One of the main risks was the blocks that could fall from a 40-metre-high, 15-metre-wide moch\u00f3n, located on one of the quarry’s usual passageways. This represented a potential risk for the installations and the workers themselves. Therefore, a series of actions were carried out to stabilise these blocks and protect the area.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    To secure the area, two types of actions were carried out: 1. An active solution to prevent the larger blocks from being mobilised. This system consists of: – ICAF 44 double cable flexible anchors, which fix the unstable blocks to the part of the rock massif that is sound. – HEA 300×300-10 cable net, a cable net with a wire knot of very high resistance and rigidity, which retains the unstable blocks as a girdle. – Steel cables, which distribute the tensions of the cable net to the flexible anchors embedded in the ground. 2. In addition, a passive solution, consisting of: – A dynamic barrier RB 3000, 6m high and 150m long. The function of this barrier is to stop the smaller blocks that could fall so that they do not affect the quarry installations. Both the HEA 300-8 cable net and the dynamic barrier have CE marking and full-scale tests in accordance with current regulations, which guarantees their performance.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
