The Wales National Mining Memorial and Gardens will be unveiled in Senghenydd at lunchtime.
It features a path, with tiles each dedicated to the 198 mining disasters that have happened across Wales.
More than 5,000 people have died in those disaster over the last 250 years; more than 1,000 in the last 100 years.
There is also a tile acknowledging the lives lost in other mining explosions and tragedies, and mining-related illness.
This tile includes a reference to the four victims of the Gleision disaster, in 2011, with the hope that it will be the last such tragedy.
A wall of remembrance will also mention all of the men who died at the two Senghenydd disasters, in 1913 and 1901.
The day of commemoration will begin with the sounding of the original Universal Colliery pit hooter, which will ring out down the Aber Valley at 8.10am, as it did 100 years ago.

The National Union of Mineworkers say they're still hopeful that the troubled Unity Mine near Neath can be saved, after it was announced that the plant had been placed into administration.
Bosses at the drift mine - which employs 220 people - were meeting with apprentices today, with administrators due to meet the rest of the workforce on Monday.
Richard Morgan reports.
"The potential investment and returns for that investment are huge in this particular mine" says Wayne Thomas, from the National Union of Mineworkers.
"The access is already there, and the working methods could be adapted slightly.
"But the investment returns are there for the longer term, and I think there's stability there... for these individuals in South Wales who want to work in coal mining."
Economy Minister Edwina Hart says the Welsh Government is continuing to work with the owners of Unity Mine to secure its future.
"Over the last few years, the industry has experienced difficulties with the fall in global coal prices which have placed considerable financial pressure on operators" she says.
"While we are working with company to offer assistance, in compliance within state-aid rules, there are wider financial pressures and challenges that have meant that the company has had to take this decision."
"Discussions with third party investors are on-going, and I welcome the Director’s intention to protect the current work force while fundraising negotiations are continuing with various parties to seek to secure the long term future of the Mine and its highly skilled workforce."
