According to the characteristics of the ecological infrastructure of coal-based cities, the ecological infrastructure is divided into two subsystems:natural infrastructure subsystem and artificial infrastructure subsystem. According to each subsystem and its main components(such as atmosphere, green space, hydrology, traffic and transportation), 36 indicators were selected to establish the evaluation system. In addition, the evaluation model was established by means of mean square deviation method and composite index method, and a dynamic analysis was carried out on the ecological infrastructure quality of Huainan City in 2006-2015. The results show that the composite index of ecological infrastructure in Huainan City in 2006-2015 remained at the medium level, and the natural infrastructure at the worse and poor levels, while the artificial infrastructure remained at the medium and excellent levels.展开更多

This project aims to address the extensive impact of coal mining on the environment, infrastructure, and overall safety, focusing on the Shigong River area above the working face. The study employs qualitative and quantitative analyses, along with on-site engineering measurements, to gather data on crucial parameters such as coal seam characteristics, roof rock lithology, thickness, water resistance, and structural damage degree. The research encompasses a multidisciplinary approach, involving mining, geology, hydrogeology, geophysical exploration, rock mechanics, mine surveying, and computational mathematics. The importance of effective safety measures and prevention techniques is emphasized, laying the foundation for research focused on the Xingyun coal mine. The brief concludes by highlighting the potential economic and social benefits of this project and its contribution to valuable experience for future subsea coal mining.展开更多
