Descrição detalhada da prática ou projeto

The methodologies evaluated have been adjusted to the usual way of working in the area, without considering alternatives for the use of the machinery, contrasting the yields associated with the modality of taking out cups or of complete tree as biomass (chips) and conditions. The success of obtaining forest products, whether wood or biomass, is subject to accessibility to the stands under treatment, to the distances of take-off and unloading to which the products must be subjected and the possibilities of access to heavy machinery or transport elements of adequate dimensions. This is why there have been a series of activities complementary to the performance prior to the work, such as the scarification of the track and the pruning of feet to facilitate the access of the vehicles, the reconstruction of slopes and the correction of hours and roads of take out.

Plot 1_Baldíos: Plot with an area of ​​4.2 ha. The slope is between 50% and 100%. The stonyness is 30% and during the execution of the works it has been found that around 35% of the area presented abundant mud. The maximum distance to the track is 200 meters. The loading dock is at a maximum distance of 150 meters from the track. The presence of holm oaks is significant; however, the operations of attachment and cutting can be carried out without being affected. The species that has been harvested has been the pinion pine (Pinus pinea) with pyramidal crown morphology. According to the Management Project, plot 1 has the following dasometric values ​​(shared with plot 2): 1,582 feet / ha, with 737 feet / ha with a diameter of less than 12 cm, 786 feet with a diameter between 12.5 and 22.5 cm, and 59 feet between 22.5 and 32.5 cm.

Plot 2_Baldíos: Area of ​​4.0 ha. The slope is between 50% and 100%. The stonyness is 30% and during the execution of the works it has been found that around 40% of the area presented abundant mud. The maximum distance to the track is 175 meters. The loading dock is at a maximum distance of 50 meters from the track. As in plot 1, the presence of holm oaks is significant; however, the operations of attachment and cutting are perfectly compatible.

Plot 3_Baldíos: Area of ​​3.7 ha. The slope is between 50% and 130%. The stonyness is 30% and during the execution of the works it has been found that around 40% of the area presented abundant mud. The maximum distance to the track is 80 meters. The loading dock is at a maximum distance of 1,000 meters from the track. The presence of holm oaks is significant; however, the operations of attachment and cutting can be carried out without being affected.

El desarrollo de los trabajos en la zona de estudio ha estado condicionado fundamentalmente por el efecto de la pendiente y la presencia de agua y barro en el terreno, determinando y condicionando la adherencia de los medios que intervienen en la extracción (desembosque) a las zonas de acopio de los pinos cortados. En estas zonas de acopio, ubicadas a lo largo de una faja cortafuegos , el espacio disponible y su accesibilidad es suficiente para el desarrollo de las operaciones de astillado, carga y transporte del producto generado

The development of the works in the study area have been fundamentally conditioned by the effect of the slope and the presence of water and mud on the ground, determining and conditioning the adhesion of the means involved in the extraction (disembarkation) to the areas of gathering the cut pines. In these collection areas, located along a firewall, the available space and its accessibility is sufficient for the development of the chipping, loading and transport operations of the generated product.

Descrição detalhada da prática ou projeto

The demonstration project for the use of biomass in Andalusia has developed actions on a plot of this group of mountains included in barracks D (cantons 33 and 34). The actions have been the measurement of the processes derived from the use of this forest, granted by the Ministry of Environment to a private forestry company. This use has consisted of a cut made on the mass of Pinus pinaster to make a substitution of species and a successive clearing on Pinus pinea. The work of this demonstration project in Monte Caballeras has been the monitoring, control of times and yields of the execution of the exploitation by the winning company, without affecting the organization of its work. The land where time tracking has been carried out has an area of ​​10.98 ha, an average slope of 45%, N-NE orientation, terraced and without significant rocky outcrops.

The data collection has been carried out from October 2010 to June 2011. On the one hand, the mass has been characterized by conducting a previous inventory, the attachment of type trees and the measurement of modular values. On the other hand, the time control of the development of the works has been carried out by continuous timing. It has also had a portable scale that has allowed the weighing of the trucks and the self-loading. The implementation of the use has been conditioned by the high slope that has limited the transit of machinery, relying on fire belts and take-off tracks.

SURVEY

• MANUAL SURVEYING

• MECHANIZED SURVEYING

HAULING

• The landing has been carried out in two phases. In the first one, the whole tree meeting was carried out on the drainage tracks by dragging through contour lines.

• Second phase of disembarkation, the double axis autoloader (VALMET 860) unsealed the timber logs and tree canopies or remains destined for biomass to a passable fire belt giving rise to differentiated batteries. The average height of the cup stack was 2.5 meters.

CHIPPER

• The chipping has been carried out during the spring with the chipper on a chassis of wheels and towed (JENZ HEM651DQ) having obtained a fairly homogeneous splinter in size, with moderate presence of whole needles and absence of whole corsages.

• The last activity of the exploitation is the loading of the trailer truck to transport the splinter from the loading dock to the consuming plant.

Highlights the lower costs of the stand where it has been possible to perform the mechanized attachment, since for the meeting and disembarkation the work of the tractors has not been necessary to be able to travel the entire work area the autoloader. During material processing there is a significant variation in moisture content. Thus, it has gone from 51% of moisture in the standing tree, to 37% of splintered feet after 5 months from the cut, to a final percentage of 29% in the splinter destined for the plant.
