露天高岭土矿山地质环境问题与土地资源再利用研究

Geological Environment and Reuse of Land Resources of Open-pit Kaolin Mine

茂名市高岭土矿资源丰富,其中山阁矿区高岭土开采规模较大,矿区共形成10个高岭土采坑,对土地资源的破坏主要表现为挖损和占压。矿区实施露天采场截排水工程、边坡中部挡土墙工程等治理矿山地质灾害;采矿活动过程中,采取各种防护措施,减少水土流失,在施工结束后立即对破坏的土地进行整治,恢复原利用功能,控制土地资源的破坏。采矿结束后,复垦土地面积275.7353 hm^(2),土地复垦率为100%,完成土地资源保护和再利用。

Maoming City is rich in kaolin mineral resources,among which Shange mining area has a large kaolin mining scale.There are 10 kaolin mining pits in the mining area,and the damage to land resources is mainly manifested as excavation loss and occupation.Mining area adopts open-pit stope interception,drainage engineering,slope retaining wall engineering and so on to control mine geological disaster;in the process of mining activities,various protective measures should be taken to reduce soil and water loss,and the damaged land should be remedied immediately after the completion of construction to restore the original utilization function and control the destruction of land resources.After the end of mining,the reclaimed land area is 275.7353 hm^(2),the land reclamation rate is 100%,and the protection and reuse of land resources have been completed.
