Pyllau Glo yng Nghymru/ Coal Mines in Wales

Roedd angen mawr am lo ar gyfer tanwydd i’r diwydiannau copr, gweithfeydd haearn a rheilffyrdd. Defnyddiwyd glo hefyd i gynhesu adeiladau ac i goginio bwyd. Roedd De Cymru yn enwog yn fyd eang am ei byllau glo. Yn Bari roedd y porthladd allforio glo mwyaf yn y byd. Caerdydd oedd yr ail gan fod glo yn cael ei gludo yno ar y rheilffordd.

Ar ôl y Rhyfel Byd Cyntaf, roedd llai o ofyn am lo wrth i ddiwydiannau ddefnyddio olew a phrynu glo’n rhatach dramor. Dioddefodd y pyllau glo, collodd 14,000 o ddynion eu gwaith wrth i 241 o byllau glo orfod cau.

Coal was an important commodity to fuel the copper, ironworks and railway industries. Another important purpose of coal was to heat buildings as well as to cook food. South Wales became famous globally for its coal mines. Barry was the largest coal exporting port in the world and Cardiff was the second largest as coal was transported there by rail. After the First World War, there was less demand for coal due to industries using oil. Cheaper coal was also imported. The Welsh coal mines suffered. By 1936, 140,000 men had lost their jobs as 241 mines were closed because they were not making enough money.
