Abstract Floor water outburst caused by structure is one of the common forms of mine water damage, and underground control is difficult and expensive. Taking the regional exploration and control of Gubei Mine as an example, this paper introduced the technical scheme, implementation process and effect verification of regional exploration and control technology in structural control. Through the construction of forty-three directional horizontal branch holes, advanced regional exploration and high pressure grouting were carried out. The results showed that the ground area exploration control technology had less risk, higher grouting pressure, and better control effect than underground control construction, which provided a basis for safe mining in mining area.
