The Associated Press reports operators of the Pasta de Conchos mine should have avoided a build-up of gases and coal dust by installing ventilation or sealing off affected areas that could have avoided the February 19 explosion.

A summary of the commission's report details the fault lay with the mine's management and in part with the country's labour department, which failed to enforce demands made on the mine.

"The disaster was caused in part by negligence and serious omissions by the operators of the mine, given that they did not comply in a timely way with measures demanded by labour authorities," the report said.

"There was also negligence and omission on the part of authorities at the Labour Department because they did not ensure the implementation of the measures ... or order the mine closed."

Sixty-three miners died in the explosion and attempts to retrieve the bodies were called off after the site was deemed too unsafe to enter and likely to be contaminated with toxic gas. Only two bodies were pulled from the mine before rescue efforts were halted.

Mine operator Grupo Mexico SAB de CV has insisted the mine met safety standards. Five of the mine's management were ordered to stand trial on negligent homicide charges by a judge in March last year.
