Resource sustainable exploitation-utilization strategy of the Laochang in Lancang,Yunnan

Resources exploration of the Laochang mining area,Lancang,has obtained a great breakthrough in recent years,not only increased greatly in traditional resources,but also discovered a new medium-sized Cu deposit and a large-extra large potential porphyry Mo(Cu) deposit in deep.Resource crisis in the mine has been relieved and a new development opportunity has been found.On the basis of analysis to status,potential and sustainable utilization of resources,and according to the geological characteristics,degree of exploration and utilization difficulty of mineral resources in the area,they can be divided into traditional resources,the recent replacement resources and mid-long term replacement resources.The paper also points out that people should protect the traditional resources in storage capacity and extend their service life.Recent replacement resources are expected to explored and used gradually through the combination of exploration and mining.The exploration and comprehensive evaluation on the mid-long term replacement resources should accelerate to take over the safety of resource fully.
