镜铁山矿区山高坡陡,植被稀疏、坡面破碎、沟道强烈侵蚀、流域内松散固体物质储量丰富,环境地质条件较差。矿区沟谷泥石流具有多期性,目前处于发育旺盛期,泥石流暴发频率较高,灾害严重,直接威胁着矿区的安全生产。本文在深入探讨泥石流发育特征的基础上,系统论述了泥石流的防治工程对策,采用生物工程与拦挡工程措施可有效的减轻泥石流灾害,逐步恢复区域生态环境,取得良好的防治工程效果。
The mountainous and steep slopes of Jingtishan Mining Area are steep with sparse vegetation, broken slope and strong channel erosion. The loose solid material in the basin is rich in reserves, and the environment and geological conditions are poor. The debris flow in the gully area of the mining area is of a multi-period nature. At present, it is experiencing a vigorous development. Debris outbreak frequency is high and the disaster is serious, directly threatening the safe production in the mining area. Based on the in-depth discussion of the development characteristics of debris flow, this paper systematically discusses the countermeasures of prevention and treatment of debris flow, and adopts bioengineering and block engineering measures to effectively reduce the debris flow disasters and gradually restore the regional ecological environment and achieve good prevention and treatment results.
