Abstract: In order to solve the existing problems of low lifting capacity and high production cost of Shanghe-Wangyu Mining Area of Lunan Mining Co.,Ltd.,the joint development of Shanghe mining section and Wangyu mining section which are under construction is designed,based on the fully utilization of the existing development projects,the optimization of the development system of ShangheWangyu Mining Area is done by means of comprehensive comparative analysis method.According to the construction status and design situations of the development system of ShangheWangyu Mining Area,two integrated development schemes and one subdivision development scheme are proposed.The comprehensive comparative analysis of the three schemes are conducted from the aspects of infrastructure investment,infrastructure time,annual operating expenses,downtime and maximum capacity improvement.Finally,the integration and development scheme of Wangyu main well is determined as the best one among the three alternatives.The scheme can not only effectively solve the problems of insufficient lifting capacity and high production cost,but also has little impact on normal production of the mine,which provides a certain space for expansion of the mine and generating more significant economic benefits.
