Abstract: In order to popularize the underground reservoir technology in coal mine area, applying system engineering theory and method, we analyzed the standards about six key technologies of underground reservoir (water yield prediction, reservoir site selection, reservoir capacity determination, dam construction, safety operation, water quality guarantee), constructed the standards framework of coal mine underground reservoir technology and described its connotation. We proposed the implement method of coal mine underground reservoir technology standards based on PDCA circulation. According to these, we described the standard formulation and implementation of Shenhua Coal Mine underground reservoir technology, proposed suggestions for coal mine underground reservoir technology standards, which can provided technology guideline for widespread application of coal mine underground reservoir technology.
