|
|
A VERY BRIEF INTRODUCTION TO MINING AT PANASQUEIRA
Mechanized room and pillar stoping is the principle mining method used at Panasqueira. It is made possible by the sub-horizontal nature of the Quartz veins and the very structurally sound nature of the host rock. Underground supports are seldom needed, but when argillaceous faults are encountered, concrete reinforcement is used, with arches either side of such faults in the main drives. When large opening are needed, rock bolts, screen and shotcrete provide the necessary support.
Stoping begins with ramps being driven to access the mineralized veins, in those areas where diamond drilling has indicated quartz intersections equal to or above 18 cm.
When a vein is accessed, it is blocked out on a basic 100m by 100m pattern. Ore passes of 1.8 metre diameter are generally bored near the drive/panel intersections. Ore can then be dropped down to the main haulage levels. Chutes are installed in the bottom of the ore-passes to facilitate the loading of the wagons.
Blast holes are drilled 2.4 metres in length and are 43mm in diameter.
There are four main levels in the mine, and all levels are connected by ramps. Level 530mRL (metres above sea level) is the main water drainage level of the mine. It lies between level 2 (560mRL) and Level 3 (470 mRL).
Below level 2 (560mRL) is the crusher. Ore above level 2 (560 mRL) is fed from ore passes (bins) into 4 Ton self-tipping rail cars and hauled by electric and diesel trolley locomotives to the ore chute on level 2 (560 mRL). The level 2 (560 mRL) ore chute feeds the underground crusher.
Ore from below Level 2 is trammed on Level 3 to the winze where the rail cars are individually hoisted to Level 2. From this shaft the cars are trammed to where they self-dump into the crusher ore chute. The underground crusher feeds ore to a conveyor belt in the Santa Barbara hoisting ramp.

Thank you Tobi.
We have worked very hard to acquire some very nice Ferberite specimens from Panasqueira. Panasqueira does produce copper and tin concentrates for export, but Tungsten is the most important metal at the mine. In fact without Tungsten there would be no Panasqueira.
By the way we have been promised some representative samples (ca. 250 gram each) of all the concentrates from Panasqueira – tin, copper, tungsten – and when properly exhibited these should also add a lot of depth to our collection.

That's right, not too common. The more I like this sample, the fluorites are well developed with an interesting structure (kind of intergrown cuboctahedral crystals?) and have a wonderful dark blue colour in contrast with the associated minerals. Panasqueira is not a main focus of mine but I like the minerals from that deposit - especially when they are combined in such a colourful piece!

Tobi

Pity Panasqueira is not your mine too. :)
I will be posting some pictures of another Fluorite specimen soon in which the Fluorite occurs as frosted blue cubic crystals with Fluorapatite.
We also have some very nice Cassiterite specimens from Panasqueira too, nothing like the material we have from Viloco, but still an important addition to our suite of Panasqueira minerals.

Mineral Collecting at Panasqueira
During most of the life of the Mine, its owners and operators have had a strict no mineral collecting policy. One of the conditions of employment requires all workers in the mine to have bags, helmets and work clothing checked before they leave the mine.
In Barroca Grande, the mine operates a mineral shop. Mine workers are encouraged to take any specimens they find in the mine during the course of their working activities to the crystal shop. The proceeds of the sale of the minerals so found benefit the shareholders and the local community. This is a really fine win-win situation for all parties.
