Ecological Characteristics and Occupational Health Effects of Deep Mines in China: A Review

With the depletion of shallow mineral resources, deep shaft mining has become an inevitable trend, but there is a lack of systematic review on the hazards of deep shaft mining ecological environment on miners' occupational health. The aim of this paper is to study the impact and main hazards of deep shaft mining ecological environment on miners' occupational health, summarize the existing research results and reveal their limitations, and put forward the latest targeted improvement technologies. The conclusions show that the environmental characteristics of deep mine dust, noise, and high temperature seriously jeopardize occupational health. Pneumoconiosis has become one of the biggest threats, with nearly 14,000 new cases per year since 2009; harmful noise exposure is widespread in deep mines, directly jeopardizing occupational health, with a detection rate of 29.96% of hearing impairment among China's 480,200,000 miners; and the average ground temperatures at the current mining depths of -1,000 m and -2,000 m are 41.84 degrees C and 69.62 degrees C, respectively, which are very likely to trigger a variety of heat-related diseases in miners. Miners with a variety of heat-related illnesses. The hazards of these environmental features are seriously underestimated.
