Under the new rules, coal mining enterprises will put aside at least CNY 30 ($4.80) for each ton of coal output of mines that have high levels of gas and CNY 15 ($2.40) for other less dangerous mines. The standard is set at CNY 5 ($0.80) for surface mines. The funds will be used for improving safety facilities, safety education and preventions of health damage, underground shelters and monitoring equipment.
