In the context of increasing demand for coal mine resources in China’s current socio-economic development, traditional mining methods have been difficult to effectively meet the requirements of safety production and environmental protection. As a result, coal mine filling mining technology has emerged, which can effectively achieve the goal of controlling surface subsidence in practical applications, while also significantly improving the recovery rate of coal resources. Based on this, this study will first elaborate on the characteristics of filling mining technology, and then analyze the key points of the application of supporting technology for mechanical and electrical equipment in the corresponding working face based on actual cases, in order to provide support for improving the efficiency of coal mining.
