GA-RANKUWA - The state on Monday asked the Ga-Rankuwa Magistrate's Court for another postponement in the case involving 259 Lonmin employees.
The workers were part of the 3,000 protesters who clashed with police at the Marikana mine, where 34 people were shot dead and 78 others injured.
According to prosecutors, police are still investigating the matter and need more time to conclude their probe.
Only 24 workers appeared in court on Monday to face charges of murder and public violence.
The state said miners should not be granted bail because it could jeopardise the case.
The prosecution called the head of the Potchefstroom detective unit, Gideon van Zyl, to testify in the case.
He said workers should be kept in custody while police finalise their investigation.
The court also heard from a state witness who said police were checking if the miners had previous criminal records and pending cases.
