Abstract: The mining technology of orebody with interlayer or broken zone has always been a critical problem in mining industry. Aiming at the above orebody with interlayer or broken zone ， different mining methods are adopted to carry out adaptive mining on upside and downside deposit. However， restricted by geologic characteristics， operation safety and mining cost， the method of mining simple orebody and giving up complicated orebody is usually adopted， which caused a permanent loss of mineral resources. In this paper， guided by the concept of "synergetic mining"， the synergetic mining technology of complicated difficulty mined orebody with interlayer or weak broken zone is proposed. According to the basic principal of the mining technology， the mining operation of interlayer or weak broken zone can be done firstly， so， the security risks can be removed fundamentally and the goal of the synergetic operation of mining process and synergetic management of ground pressure can be realized， besides that， the technical benefits of synergetic mining can be maximized. Taking a phosphorite mine and a copper polymetallic mine for the study examples， according to the specific mining technical conditions of them， the synergetic mining scheme of interlayer removal and groove cutting with different thickness of interlayer and upside and downside deposit is proposed. At the same time， based on the idea of pressure synergy or environmental regeneration， a synergetic mining scheme of weak broken oxidation zone is developed to improve recovery efficiency and security. The proposed synergetic mining schemes in this paper can provide technical reference for the mining operation of similar orebodies in our country， besides that， the practice guidance value of "synergetic mining" concept in the mining operation of similar complex difficult mined orebodies is enhanced to some extent.
