Abstract(s)
O fogo é um evento natural na maioria dos ecossistemas florestais, há 400 milhões
de anos que este fenómeno ocorre sem a intervenção humana. O fogo pode ter efeitos
positivos ou negativos no meio ambiente. Entendendo isto percebemos a importância
do uso do fogo para promover a saúde da floresta, proteger os recursos naturais e
alcançar a sustentabilidade dos ecossistemas. Contudo os incêndios florestais, são
fogos que não são planeados, são difíceis de prever e sem maneira de antecipar a sua
gravidade. As máquinas de rastos podem e devem dar um importante apoio na
mitigação deste problema.
No presente trabalho são identificados os riscos de operação das MR nos
incêndios rurais, fornecendo-se simultaneamente informação relativa à capacidade e
limitações de operação das diferentes tipologias de máquinas pesadas.
Na época de incêndios, estas máquinas de rastos são usadas na primeira
intervenção e durante o resto do ano, trabalham na floresta, nas operações
preventivas de silvicultura. Nas máquinas de rasto (MR) podem ser acopladas diversos
tipos de alfaias conforme o tipo de incêndio para complementar o seu trabalho. Assim
neste trabalho será analisado, movimentações e despachos das MR, as principais
dificuldades no uso das máquinas de rasto nos teatros de operações e a sua
manutenção.
A utilização crescente das máquinas de rasto, permite realizar um combate direto
ou indireto, abrindo aceiros ou caminhos que permitem a progressão das equipas
terrestes ou helitransportadas, criação de descontinuidades do combustível expondo o
solo mineral não combustível o que pode parar ou abrandar o incêndio numa zona,
impedindo a sua continuação.
Fire is a natural event in most forest ecosystems, for 400 million years this phenomenon has occurred without human intervention. Fire can have positive or negative effects on the environment. Understanding this, we realize the importance of using fire to promote forest health, protect natural resources and achieve ecosystem sustainability. However, forest fires are fires that are not planned, and they are difficult to predict their severity. Track machines can and should provide important support in mitigating this problem. In this work, the risks of TM operations in rural fires are identified, providing information on the capacity and limitations of operation of different types of heavy machinery. In the fire season, these TM are used in the first intervention and during the rest of the year, they work in the forest, in preventive forestry operations. Different types of implements can be attached to the TM, depending on the type of fire, to complement your work. Thus, in this work, TM movements and dispatches will be analysed, the main difficulties in the use of track machines in theaters of operations and their maintenance. The increasing use of TM makes it possible to carry out direct or indirect combat, opening firebreaks or paths that allow ground or Heli transported teams to progress, creating fuel discontinuities exposing non-combustible mineral soil, which can stop or slow down the fire, preventing its spreading.
