R E S U M E N ABSTRACT
A R T E P R E V I O A R T E P R E V I O
En la gran minería se procesa una gran cantidad de material, los grandes proyectos mineros de chile procesan cerca de 180 mil toneladas de mineral por día en cada faena lo que obliga a tener sistemas de transporte de mineral confiables que logren abastecer a sus distintas plantas con los minerales extraídos de la mina. Se ocupan, luego del proceso de chancado del mineral extraído de la mina, sistemas de correas que transportan los minerales desde el chancado hacia las plantas de lixiviación o concertados. In large-scale mining, a large amount of material is processed. The large mining projects in Chile process about 180,000 tons of ore per day at each site, which makes it necessary to have reliable ore transport systems that are able to supply their different plants with the minerals extracted from the mine. After the crushing process of the ore extracted from the mine, they deal with belt systems that transport the minerals from the crushing to the leaching or concerted plants.
Los sistemas de correas, muchos de ellos de varios kilómetros de largo pasan por tuéneles y por sectores estrechos y de difícil acceso, esto ocurre ya que comúnmente, y por principalmente para ahorrar costos de los proyectos se hacen túneles estrechos y correas de baja altura. The belt systems, many of them several kilometers long, pass through tunnels and through narrow and difficult-to-access sectors. This usually occurs, and mainly to save project costs, narrow tunnels and low-height belts are made.
HOJAS DE SUSTITUCIÓN (REGLA 26) De acuerdo a los autores James R. Amstrong y Raji Menon, los mineros tienen que trabajar en un entorno laboral en cons-tante transformación. Algunos trabajan sin luz natural o ventila-ción, excavando la tierra, extrayendo material y, al mismo tiempo, tomando medidas para evitar que se produzca una reac-ción inmediata de los estratos adyacentes. A pesar de los impor-tantes esfuerzos realizados en muchos países, la tasa mundial de víctimas mortales, lesiones y enfermedades entre los mineros demuestra que, en la mayoría de ellos, la minería sigue siendo el trabajo más peligroso en relación con el número total de trabaja-dores dedicados a esta actividad. En efecto, aunque la minería sólo emplea al 1 % del total de trabajadores, es responsable de cerca del8%delosaccidentes laborales mortales (15.000 al año aproximadamente). A pesar de no disponer de datos fiables sobre accidentes, sí resulta significativo su número así como el de traba-jadores afectados por enfermedades profesionales (pneumoco-niosis, pérdida de audición y lesiones causadas por vibraciones), cuya incapacitación prematura e incluso fallecimiento son direc-tamente atribuibles al trabajo. SUBSTITUTE SHEETS (RULE 26) According to authors James R. Armstrong and Raji Menon, miners have to work in a constantly changing work environment. Some work without natural light or ventilation, digging up the earth, extracting material, and at the same time taking steps to prevent immediate reaction from adjacent strata. Despite significant efforts in many countries, the global rate of fatalities, injuries and illnesses among miners shows that, in most of them, mining remains the most dangerous job in relation to the total number of workers dedicated to this activity. Indeed, although mining only employs 1% of all workers, it is responsible for about 8% of fatal occupational accidents (approximately 15,000 a year). Despite the lack of reliable data on accidents, their number is significant, as is the number of workers affected by occupational diseases (pneumoconiosis, hearing loss and injuries caused by vibrations), whose premature incapacitation and even death are direct -fully attributable to work.
Por lo tanto, uno de los objetivos del presente proceso y sistema es buscar disminuir la exposición del riesgo de personal de limpieza y despeje, como así generar un circuito cerrado de limpieza dentro de los túneles donde pasan los sistemas de correas transportadoras. Therefore, one of the objectives of this process and system is to seek to reduce the risk exposure of cleaning and clearance personnel, as well as to generate a closed cleaning circuit inside the tunnels where the conveyor belt systems pass.
HOJAS DE SUSTITUCIÓN (REGLA 26) El proceso de transporte de material contempla diferentes etapas: SUBSTITUTE SHEETS (RULE 26) The material transport process includes different stages:
1. Al momento de alimentar las correas, material grueso y muchas veces inchancables (fierros, material de mayor dureza) pasan de largo y terminan dañando la cinta de la correa. Esto genera surcos y fisuras que se llenan con material seco y húmedo. 1. When feeding the belts, thick and often unbreakable material (iron, harder material) pass by and end up damaging the belt tape. This creates grooves and fissures that are filled with dry and wet material.
2. Al llegar a una planta de transferencia o sistema de alimentación el mineral es vaciado a su lugar de destino o a otra correa, al ocurrir esto, y donde termina la correa se instalan sistemas de raspado los que tienen como objetivo eliminar el material adherido sobre la superficie de la cinta. 2. Upon arrival at a transfer plant or feeding system, the ore is emptied to its destination or to another belt. When this occurs, and where the belt ends, scraping systems are installed, which aim to remove the material adhered to the belt. the surface of the tape.
3. El lado superficial de la cinta, y el cual transportó el mineral, ahora se encuentra boca abajo mirando el piso hacia la dirección opuesta al de descarga. 3. The shallow side of the belt, which carried the ore, is now upside down facing the floor in the opposite direction of discharge.
En la figura 1 se observa que el material no raspado (A) termina siempre debajo de la correa. Figure 1 shows that the unscraped material (A) always ends up below the belt.
Los riesgos asociados a los materiales acumulados bajo correa dicen relación con el hecho que una vez que se acumulan grandes cantidades de material bajo correa estos terminan erosionando polines y eventualmente causando cortes de correas o incendios por exceso de calor consecuencia de roce de materiales.The risks associated with materials accumulated under the belt are related to the fact that once large amounts of material accumulate under the belt, they end up eroding idlers and eventually causing belt cuts or fires due to excess heat as a result of material friction.
El corte de correa en un sistema de transporte puede parar toda la producción de una faena minera, frenando la alimentación de minerales frescos a las plantas de A belt cut in a conveyor system can stop the entire production of a mining site, stopping the supply of fresh minerals to the processing plants.
HOJAS DE SUSTITUCIÓN (REGLA 26) beneficio. Esto puede genera pérdidas en la falta de entrega de concentrados por millones de dólares. SUBSTITUTE SHEETS (RULE 26) benefit. This can generate losses in the lack of delivery of concentrates for millions of dollars.
Debido a los cortes sobre correa material adherido pasa por sistema de raspaje y luego, por vibración de polines termina depositándose en la mitad del piso de la correa. El material no cae por rebalse sino por desprendimiento vertical (V). (Figura 2). Due to the cuts on the belt, adhered material goes through a scraping system and then, due to the vibration of the idlers, it ends up being deposited in the middle of the belt floor. The material does not fall by overflow but by vertical detachment (V). (Figure 2).
En general, la limpieza y despeje de los pasillos en túnles de faenas mineras es realizado casi en forma manual por el personal, en cuyas operaciones utilizan equipos de picado o "cachorreo" para romper el material y mediante palas se vuelve a colocar sobre la correa transportadora para su despeje. De esta forma se cumple con el Reglamento de Seguridad Minera que establece que todos aquellos elementos estructurales y de apoyo como pasillos, estructuras, grúas, cables y otros componentes, deberán estar sujetos a estrictas normas de mantención y control. In general, the cleaning and clearing of the corridors in tunnels of mining works is carried out almost manually by the personnel, in whose operations they use chopping equipment or "pumping" to break the material and by means of shovels it is placed again on the belt. carrier for clearance. In this way, the Mining Safety Regulations are complied with, which establish that all structural and support elements such as corridors, structures, cranes, cables and other components must be subject to strict maintenance and control standards.
El despeje también se efectúa mediante equipos móviles a control remoto de bajo perfil o con personal en detenciones de planta. La consecuencia negativa de estos métodos es que queda todo el material en pasillos de tránsito. Este material termina compactándose y aumentando la altura del piso de los pasillos, generando así, una situación de riesgo para quienes transitan por los túneles o espacios estrechos. The clearance is also carried out by low-profile remote-controlled mobile teams or with personnel in plant stoppages. The negative consequence of these methods is that all the material remains in transit corridors. This material ends up compacting and increasing the height of the floor of the corridors, thus generating a risk situation for those who pass through the tunnels or narrow spaces.
HOJAS DE SUSTITUCIÓN (REGLA 26) Para posteriormente remover el material acumulado de pasillos se utilizan comúnmente personas con picotas, palas y rotomartillos, carguío de material suelto con minicaragdor sobre dumper móvil, transporte de material fuera del sistema de correa mediante dumper. Este sistema o procedimiento es riesgoso, intensivo en mano de obra y bloquea los túneles al transitar con equipos móviles dentro de ellos. Adicionalmente, hoy en día no se puede echar material sobre la correa de forma manual una vez que esté en movimiento ya que esto es un peligro para el operario y además las correas son muy altas para esto. La forma tradicional es acarrear el material es mediante un dumper móvil fuera del túnel para acopiar ese material y luego riengresarlo mediante algún stockpile al proceso. SUBSTITUTE SHEETS (RULE 26) To subsequently remove the accumulated material from the corridors, people with pickaxes, shovels and rotary hammers are commonly used, loading of loose material with a mini-loader on a mobile dumper, transport of material outside the belt system by means of a dumper. This system or procedure is risky, labor-intensive, and blocks the tunnels when mobile equipment moves through them. Additionally, today it is not possible to manually pour material on the belt once it is in motion, as this is a danger for the operator and, moreover, the belts are too high for this. The traditional way is to transport the material by means of a mobile dumper out of the tunnel to collect that material and then re-enter it through a stockpile to the process.
En la industria minera se han utilizado grandes transportadores autónomos que son montados en equipos móviles. Por ejemplo, el documento US 6.008.894 enseña que en las operaciones de minería de vetas bajas se utiliza un portador de puente movilizado con banda ancha y perfil bajo. Incluye un bastidor portador que lleva el sistema de propulsión y que soporta el brazo de recepción, el brazo de descarga, el conjunto de la cabina y el toldo. El portador de puente movilizado preferido es propulsado por orugas e incluye al menos un par de conjuntos de orugas que son accionados por un motor hidráulico accionado eléctricamente. El brazo de recepción y el brazo de descarga están fijados juntos y cada uno está Large self-contained conveyors that are mounted on mobile equipment have been used in the mining industry. For example, US 6,008,894 teaches that a low profile, broadband mobilized bridge carrier is used in low seam mining operations. It includes a carrier frame that carries the propulsion system and supports the receiving arm, unloading arm, cab assembly, and canopy. The preferred mobilized bridge carrier is track driven and includes at least one pair of track assemblies that are driven by an electrically powered hydraulic motor. The receiving arm and the discharging arm are fixed together and each is

El brazo de recepción y el brazo de descarga incluyen conjuntos de paneles laterales de perfil bajo que permiten que el portador de puente movilizado se utilice en aplicaciones de minería de "vetas bajas". Con el fin de compensar cualquier pérdida inherente de resistencia en el brazo receptor que resulte de bajar el perfil para lograr su propósito de operar dentro de vetas bajas, los actuales brazos receptores y de descarga incorporan ciertos refuerzos novedosos, incluyendo placas de refuerzo internas que se extienden sustancialmente a lo largo de la superficie, longitud de los brazos y que está construida de una placa de acero de grueso espesor soldada continuamente al interior de cada uno de los lados de los brazos. SUBSTITUTE SHEETS (RULE 26) pivotally mounted to the support frame at a main pivot point. The carrier frame is of reinforced construction. The receiving arm and unloading arm include low profile side panel assemblies that allow the mobilized bridge carrier to be used in "low seam" mining applications. In order to compensate for any inherent loss of strength in the catcher arm that results from lowering the profile to achieve its purpose of operating within low seams, current catcher and discharge arms incorporate certain novel reinforcements, including internal reinforcement plates that are extending substantially along the surface, length of the arms and being constructed of a thick gauge steel plate continuously welded to the inside of each side of the arms.
