At least one miner was killed at Kom-Durte gold mine in Isiolo North after it collapsed.
Police said a second miner was injured and rushed to hospital after the Monday evening incident.
Ali Maran Ali was among those doing mining activities at Kom Durte when it suddenly collapsed and killed him on the spot.
Other miners managed to escape the scene. Police said another miner was injured in the incident amid calls for measures to address such accidents.
This is the latest such incident to happen at the gold mine site.
In February this year, at least three people were killed at the site after it collapsed.
Governor Abdi Guyo said his administration was offering help to those affected. He said they would take measures to ensure the safety of the miners.
The scene is Merti town, 75 kilometres from Isiolo town.
In May last year, the government ordered an immediate ban on unlicensed mining activities in the Kom region of Merti subcounty.
This was for, among other measures, an environmental audit.
The officials said then the miners were using heavy machines to crush stones in their artisanal activities, overlooking the environmental impact.
They directed those involved in the mining activities to stop operations as the National Environmental Management Authority conducts an environmental impact assessment to give the ecological guidelines before mining operations can resume.
Nema officials were directed to carry out the environmental impact assessment and give a report as soon as possible.
The gold miners were ordered to seek licenses from all the relevant government authorities before embarking on the work.
