Due to historical reasons, Zhongcun Coal Mine was classified as a "complex hydrogeological mine" in 2016. The mine can only organize production at 80% of the approved production capacity, which severely restricts the development of the mine.

　　Only by changing the "hydrogeological type" of the mine can the original approved production capacity of the mine be restored. In the past four years, all employees of Zhongcun Coal Mine have focused on this goal, made concerted efforts, worked hard, and carried out various water prevention and control work, and strictly followed the comprehensive water prevention and control measures of "physical exploration first drilling verification and geochemical exploration follow-up" to prevent water. The comprehensive improvement of the system, equipment update, staffing, technical training, and full-staff training has been completed. A set of water hazard prevention and control work system with "Nakamura characteristics" was developed. The prevention and control of water hazards in Zhongcun Coal Mine has achieved good results.

　　In 2018, it was assessed as a "water hazard prevention and control model mine" by the Jincheng Emergency Management Bureau and the Group Company. In 2019, the mine's "water hazard prevention and control evaluation system" was assessed as the third prize of innovation achievement by the Shanxi Coal Association.

　　Since the beginning of the year, the Zhongcun Coal Mine has successfully completed the change of production factors in the mine after applying layer by layer and on-site inspections by the provincial, municipal and county energy bureaus, and fully affirmed the mine water prevention and control work.

　　Recently, Shanxi Provincial Energy Bureau announced the production factors of Zhongcun Coal Mine with Document [2020] No. 159. The announcement shows that the hydrogeological type of Zhongcun Coal Mine has been changed from "complex" to "medium", and the approved production capacity has been restored from 720,000 tons/year to 900,000 tons/year. This move will help Zhongcun Coal Mine's next safe production and effective production. Important milestone.
