The explosion was the result of high gas density due to poor ventilation, said Fu Jianhua, deputy director of the administration.

The administration's director Yang Dongliang said all licenses the coal mine possessed must be revoked and the site will be shut down permanently.

Liu Jie, deputy governor of Sichuan, said the Taozigou coal mine should be shut down "as soon as possible" and production at all coal mines in the province should be suspended for an overhaul.

Meanwhile, the number of casualties needs to be verified and the injured should be treated, Yang said.

He added that a thorough investigation into the cause of the accident should be carried out so that those responsible are dealt with in accordance with the law.
