Abstract: In order to solve the deep mining water hazard prevention problem and to optimize the regional control scheme, the deep mine water detection and governance techniques of Xingtai deep mining area regional control engineering based on 3-D directional drilling was studied. The 3-D directional borehole structure and portioning holes layout were introduced to improve the flexibility and to manage mining process and mine water control process orderly. Study results shown that the control system can control the existing water inrush points, reduce the probability of water inrush, and timely block the new water inrush points to provide technical guarantee for the whole deep mining process. Research results can provide a reference for deep mine water regional control engineering design and implementation.
