This paper briefly introduces the natural geography and regional geological conditions of the Mentoukou Village coal mine, Longquan Town, Mentougou District, Beijing, and analyzes the problems of the mining geological environment and secondary geological disasters. According to the actual site conditions, the authors put forward the engineering design of treatment and management. Through combining mining environmental engineering and landscape architecture engineering design, it provides valuable experience for both the management of mining environments and amelioration of living environments.
