"The significance of the protest now is to make them realise the numbers they are looking to seal in the mine. This morning the two Solid Energy vehicles came and stopped. The drivers shook their heads, reversed and slowly drove away."
Prime Minister Bill English has agreed to meet a deputation from the families next Wednesday, followed by submissions to the parliamentary select committee on Thursday.
"I don't think Solid Energy will change its mind so it is now time to bring an independent body in. Solid Energy has to step aside - move on. I think they have under-estimated our stance," Monk said.
Anna Osborne, whose husband Milton was among the 29, said the past six years had been tough on the families.
"If Bill English is going to offer lip service then I'm not interested. We want action and action speaks louder than words," Osborne said.
"We are pushing not only to get our men out but because we all need to know the root cause behind every underground accident to ensure others don't have to go through the heartache of losing their sons, husbands or brothers, like we have."
