Abstract: The complex spatial-temporal distribution of goaf and the serious ground pressure appearance are the key technical problems restricting the recovery of tungsten ore residual resources in Southern Jiangxi Province.In order to solve the problem of recovery of tungsten mine residual resources in Southern Jiangxi Prpvince，based on the concept of "synergetic mining"，consideration of resource exploitation and hidden danger treatment，this paper puts forward the key technical scheme of synergetic mining （exploration supervision mining） for the detection of goaf，real-time monitoring of microseism and synergetic mining of residual mine in Southern Jiangxi Province，and the engineering case of a typical tungsten mine in Southern Jiangxi Province is analyzed.The results show that according to the complex spatial-temporal distribution characteristics of 31132 ore block，the whole geological model and goaf model are constructed on the basis of three-dimensional fine detection technology，and the residual ore form and quantity are accurately obtained.The ore estimation error is less than 10%.On this basis，the mining plan is made for the top pillar，the bottom pillar and the inter pillar according to the local conditions.The IMS micro-seismic monitoring system is established in the process of residual mining to monitor and forewarn the stability of the mined out area of 31132 block stope in real time，and to deal with the mined out area in cooperation with the methods of goaf closure and cemented filling，so as to realize the organic unity of the hidden danger treatment of the mined out area and the recovery of residual ore resources，complete the recovery of all the residual ore in the top pillar of 31132 stope，and create conditions for the recovery of the intermediate pillar.The above study results can provide technical reference for safe，efficient and synergetic mining of tungsten residual resources in Southern Jiangxi Province.
