Couto Mineiro do Lena (Alcobaça, Batalha e Porto de Mós), Distrito de Leiria, Portugal


- Several inactive coal/lignite mines in Batalha, Porto de Mós and Alcobaça municipalities.

Also known as "Minas da Batalha" the group of occurrences clustered in the concession "Alcanadas e Chão Preto" was one of the most important poles of Couto Mineiro do Lena (CML), wide set of coal mines/lignite layers aligned in the direction N - S along the right bank of the Lena River, which stretched for more than 10 km by the municipalities of Batalha and Porto de Mós.

Founded in 1925, the CML gathered 44 concessions some of which with no productive expression. These mines explored the levels of lignite interstratified in the Upper Jurassic carbonate complex, which were known by many outcrops, where there seems to be notes of mining activity since the first half of the eighteenth century.

Apart from the mines of Alcanadas should also be noted in this set of concessions, the mines of Bezerra, which provided until the late thirties the best coal in the region, Ferrarias and Vale Grande.

Couto Mineiro do Lena - as coorednadas indicadas são as da mina principal Bezerra ~39.60 N, -8.82 W

O Couto Mineiro do Lena, localizado na região de Porto de Mós–Batalha–Alcobaça, na envolvente da Serra dos Candeeiros, integrou diversas concessões de exploração de carvão/lignite, com maior atividade entre o final do século XIX e a primeira metade do século XX.

Embora não exista uma lista completamente fechada, devido à natureza efémera e dispersa de muitas concessões, as principais minas e ocorrências conhecidas incluem:

Bezerra (Porto de Mós) – uma das mais importantes explorações da região
Chão Preto – associada à área da Bezerra
Vale de Bragadas
Casal de Vale de Ventos (Turquel)
Moinho de António Carreira (Turquel)
Cabeço do Veado
Vale da Gunha / Gunha
Vale do Lena – várias ocorrências dispersas
Características gerais
Tipo de recurso: lignite (carvão castanho)
Depósitos associados: formações sedimentares do Jurássico
Explorações: geralmente de pequena a média dimensão, muitas vezes descontínuas e dispersas, com galerias curtas ou explorações superficiais
Contexto histórico
Período de maior atividade: final do século XIX até cerca de 1920–1940
Muitas concessões foram atribuídas em 1922, marcando um pico de registos mineiros
Uso da produção: consumo local e pequenas indústrias
Situação atual
A maioria das minas encontra-se abandonada
Estruturas podem estar colapsadas ou ocultas
Vestígios visíveis são raros: escombreiras, cortes no terreno ou entradas de galerias
Interpretação geográfica

O couto mineiro desenvolve-se ao longo de um eixo N–S com mais de 10 km, acompanhando o vale do rio Lena. As minas concentram-se principalmente:
Entre Porto de Mós e Batalha – núcleo principal, incluindo Bezerra
Prolongando-se para sul até Turquel – áreas de explorações dispersas como Casal de Vale de Ventos e Moinho de António Carreira
Coordenadas aproximadas (referência)
Zonas e Coordenadas
Centro do couto mineiro 39.0 N, -8.0 W
Bezerra (principal) ~39.60 N, -8.82 W
Batalha / Lena médio ~39.65 N, -8.82 W
Turquel (minas dispersas) ~39.47 N, -8.90 W

Resumo:
O Couto Mineiro do Lena não corresponde a uma única mina, mas sim a um conjunto de explorações de lignite dispersas, destacando-se Bezerra, Chão Preto, Vale de Bragadas e as ocorrências de Turquel, como Casal de Vale de Ventos e Moinho de António Carreira.
