The invention discloses a ground double-hole combined water inrush prevention method for overlying strata movement monitoring and
bed separation water drainage. The ground double-hole combined water inrush prevention method is suitable for treatment of overlying separation flood after mining of a water-rich stratum mine and comprises the steps that a rock stratum movement monitoring
drill hole and a
bed separation water drainage
drill hole which are adjacent to each other are constructed in the middle of a working face along the trend corresponding to the
earth surface, the rock stratum movement monitoring
drill hole is formed to monitor internal movement information of an overlying rock stratum in the working face mining process, and the
bed separation development condition is mainly mastered; and the bed separation water drainage
drill hole is used for drilling and penetrating holes based on the bed separation
generation time fed back by rock stratum movement monitoring in the arranged rock stratum movement monitoring
drill hole, drilling and hole penetration are carried out, bed separation water is drained in a staged and controlled mode, and water inrush of the working face is prevented. The drilling depth, drainage and hole penetration of the bed separation water drainage
drill hole are guided by monitoring the change of the measuring points arranged in the upper rock stratum and the lower rock stratum of the bottom interface of an
aquifer. The
utilization rate of the bed separation water drainage drill holes is effectively improved through combination of the mobile monitoring drill holes in the rock stratum and the bed separation water drainage drill holes.
