JOHANNESBURG (Reuters) - South Africa's National Union of Mineworkers (NUM) said on Friday its members will go on strike at state-run power utility Eskom, the sole provider of electricity in Africa's most industrialised economy, from Aug. 8. The strike will cause damage to business, NUM General Secretary David Sipunzi told a media briefing. (Reporting by Ed Stoddard; Writing by TJ Strydom; Editing by Stella Mapenzauswa)
