Кафяви въглища

Кафявите въглища са вид въглища с по-висока калоричност (2500 – 5000 kcal) в сравнение с лигнитните въглища.[1]

В сравнение с лигнитните съдържат по-малко влага (15 – 20%). Кафявите въглища се използват за отопление и за производство на електроенергия.

Кафяви въглища в България

Запасите на кафяви въглища в България възлизат на около 300 млн. тона. Те имат палеогенска възраст. Бобовдолският басейн е с най-големи запаси – около 190 млн. тона или 60% от запасите на кафяви въглища в страната. Въглищните пластове са на дълбочина до 700 m. Това налага подземния им добив. Благодарение на тях функционира ТЕЦ „Бобовдол“.[1]

Непосредствено след Освобождението започва експлоатацията на Пернишкия басейн. Въглищата му се използват за производство на електроенергия в ТЕЦ „Република“.[1]

Около 18% от запасите на кафяви въглища се намират в мина „Черно море“ край село Рудник, област Бургас.[1]

Други находища са край Николаево, село Брежани, както и в Разложкия и Кюстендилския басейн, които са с неогенска възраст.[1]
