作者 杨军忠 《中国金属通报》 2024年第12期47-49,共3页
我国对铝土矿资源的需求越来越大,露天采矿是广西等堆积型铝土矿采矿最常用的一种方式,具有很多的优点,投资时期短、效益高、生产速度快、采矿节约成本等,但是,露天采矿也会对地质环境带来更多的地质危害,这是由于露天采矿都是在地表进... 我国对铝土矿资源的需求越来越大,露天采矿是广西等堆积型铝土矿采矿最常用的一种方式,具有很多的优点,投资时期短、效益高、生产速度快、采矿节约成本等,但是,露天采矿也会对地质环境带来更多的地质危害,这是由于露天采矿都是在地表进采矿工作,这就很容易引起边坡发生崩塌以及雨水冲刷渗漏造成的水体污染、石漠化、植被荒漠化。因此,要对露天采矿的矿山地质环境进行治理和恢复,这样才能实现可持续发展,更好的保护环境。 展开更多

Archaeological sites are most visible records of our cultural heritage, These sites are often constructed of stone threaten by geomorphological processing, pollution, urbanization, public access, groundwater seepage and geological hazards, such as rock falls. These archaeological sites suffered deterioration and failure of some parts. Environmental hazards are the main agent responsible for the monument degrading knowledge of intensity of environmental hazards together with their aggressiveness characteristics surrounding the monumentally area which is important during all phases restoration process (both previous and to be executed in situ). The main geo-environmental hazards which affect the monuments under investigation; weathering, air pollution, seismic activity. 展开更多
