China Approves Four Mandatory Mine Safety Standards Effective in 2027

China's State Administration for Market Regulation and the National Mine Safety Administration have approved four mandatory national standards to tighten safety controls in the mining sector, set to take effect on March 1, 2027. The standards establish China's first mandatory regime for surveying hidden geological hazards, mandating full risk censuses every three years. They also introduce rigorous technical requirements for lithium-ion batteries operating in confined, high-gas underground environments, reflecting a broader policy drive toward early-stage accident prevention.

By establishing mandatory national standards, Chinese regulators are setting legally binding technical baselines for hazard identification and underground electrification. These rules place direct responsibility on mining enterprises to identify latent geological threats—such as mined-out voids and water channels—before accidents occur, while curbing fire and explosion risks linked to new energy equipment in underground tunnels.

China's market and mine safety regulators have approved four mandatory national standards aimed at strengthening accident prevention in the country's extractive industries, according to a Xinhua report published by People's Daily. The standards were organized by the National Mine Safety Administration and issued by the State Administration for Market Regulation, which also houses the Standardization Administration of China. All four standards will officially take effect on March 1, 2027. Among the measures highlighted by authorities is the Specification for Census of Hidden Disaster-Causing Factors in Mines, described as China's first mandatory national standard system targeting hidden risks in the mining sector. The standard institutes a formal regime requiring enterprises to conduct a comprehensive hazard census every three years, accompanied by differentiated, zone-by-zone mitigation and routine supplementary checks. The census framework sets binding professional criteria and clarifies enterprise responsibility across different types of mines. It mandates complete coverage of critical risk vectors, including abandoned underground voids, complex geological structures, water pathways, and gas accumulations. In addition, the rule standardizes the full workflow of risk identification—spanning geophysical prospecting, core drilling, and sample testing—to outcomes management, aiming to address hazards at the source. A second highlighted standard, Technical Specifications for Lithium-Ion Power Batteries Used in Underground Mines, focuses on the risks posed by equipment electrification in hazardous environments. Developed to address the specific perils of confined spaces and high-gas concentrations found underground, the standard establishes technical safety thresholds at both the individual battery cell level and the broader battery module level. State media did not publish the specific titles or technical parameters of the remaining two approved standards in the release. Together, however, the newly adopted rules reflect a regulatory strategy designed to institutionalize pre-emptive risk control across China's mining operations before equipment and geological vulnerabilities cause fatal workplace incidents.
