THIRD NATIONAL DAYS ON SAFETY IN THE CONSTRUCTION INDUSTRY: EXCAVATIONS. THEME 5: UNDERGROUND EXCAVATIONS AND CONTROL OF THE ENVIRONMENT IN EXCAVATION OPERATIONS. GENERAL REPORT

III JORNADAS NACIONALES DE SEGURIDAD EN LA CONSTRUCCION:EXCAVACIONES. EXCAVACIONES SUBTERRANEAS Y CONTROL AMBIENTAL EN TRABAJOS DE EXCAVACION

THE PROBLEM OF SAFETY IN UNDERGROUND WORKS, ESPECIALLY IN TUNNELS, IS FORMULATED AND SPECIAL ATTENTION IS DRAWN TO THE FOLLOWING ASPECTS: (A) TERRAIN STABILITY; (B) EXCEPTIONAL CONDITIONS (NOXIOUS GASES, THERMAL GRADIENTS, LARGE RATE OF FLOW); (C) RISK OF HANDLING EXPLOSIVES; (D) RISK OF USING ANCILLARY EQUIPMENT (MACHINES, TOOLS AND PLANTS). THE CONTROL OF THE ENVIRONMENT IS ANALYZED AND IT IS CONCLUDED THAT THE CAUSES OF DETERIORATION OF A TUNNEL ENVIRONMENT ARE: (1) OXYGEN CONSUMPTION BY THE PERSONNEL; (2) DUST FROM DRILLING OR SHEARING TOOLS; (3) GASES FROM BLASTING; (4) POLLUTION BY DIESEL ENGINES; (5) NOISE AND VIBRATIONS. THESE CAUSES CAN BE CLASSIFIED AS CONVENTIONAL; EXCEPTIONAL CAUSES ARE: (6) HIGH THERMAL GRADIENTS OF MACHINES OR TERRAIN; (7) NOXIOUS GASES IN THE TERRAIN; (8) EXCEPTIONAL AND/OR WATER TABLE RATE OF FLOW.
