摘要
Geo-environmental treatment projects and land restoration plans have not been implemented in many old mines of China.The government provides special policies and funding to solve the geo-environmental problems of those mines.It is necessary to bring up a set of design theory which is suit for Chinese conditions from the technical level.Based on the characteristics of the geo-environmental treatment projects of old mines,the paper puts forward the principle,index and process of the treatment projects and applies in the design of Fengshan limestone mine,Guangxi.The results show that:(1)The geological environment problems are complex and diverse,and the treatment projects involve a multi-disciplinary cross which are environmental geology,ecology geology,geotechnical engineering,environmental engineering and landscape works.It needs to consider the key indicators: geo-environment problems,feasibility,benefit and social demand.(2) the limestone mine in Fengshan is 134m high,and a collapse of 2.1×104 m3 happened and killed 6 people.The geo-environment problems include rockfall,rock collapse,land and vegetation destruction and landscape damage.Therefore,drainage,anchoring,rockfalls platforms and rock carvings are implemented for the purpose of transforming the mine into a sight spot in the park;(3) the treatment projects eliminate the geo-hazard and build the world-class carving attractions reflecting the benefit of the project management from the environment,economy and society aspects.
