摘要

In order to prevent and relieve coal mine water hazards in China, mine water accurate detection and efficient control techniques were studied based on applications of multiple drilling methods. Surface directional drilling was applied in deep buried areas to cover main detection and governance region. Radial jet drilling technique was applied to control shallow area, marginal region and directional drilling blind area. In areas with no ground drilling condition, underground drilling technique was applied. Accurate detection method was developed by analyzing multi source data obtained through different drilling methods. Study showed that faults can be identified by directional drilling logging data and radial jetting process data. To enhance control efficiency, non-blind borehole layout method was studied by using different kind of drilling methods comprehensively.
