Synergistic and complementary safety supervision mode in coal mines: a case of coal mining companies in China

摘要

Effective safety supervision guarantees coal mine safety production. However, the traditional supervision mode in Chinese coal mines cannot fully realize the synergistic and complementary effects of elements (i.e., safety inspectors) of safety supervision system, which causes information-isolated island, application-isolated island, and resource-isolated island. To overcome these deficiencies and improve the efficiency of safety supervision, a synergistic and complementary safety supervision mode (SCSSM) was explored in this study. After the applicability analysis of the synergistic and complementary management idea, this study creatively introduced the proposed idea to the safety supervision in the coal mine. On the basis of the deficiencies of the existing safety supervision mode and the advantages of synergistic and complementary management, the SCSSM was then established and its definite operation method was also provided. Finally, the new safety supervision mode was applied in Xinwen Mining Group Xin Julong Co., Ltd. with definite implementation method and comparative analysis. Results show that the new safety supervision mode uses lesser safety supervision resources than the traditional one. Meanwhile, the checking and rectification efficiency of hidden dangers and the project qualified rate are improved. Moreover, the number of accidents is reduced, which has significant safety, economic, and social benefits. This study can realize the synergistic and complementary effects of elements of safety supervision to improve the level of coal mine safety supervision and has high value of popularization and application.
