本文重点介绍了在岩中巷对采空区积水探放技术在鹤煤八矿3002（北）积水区进行疏放水的研究与应用，通过实施运用该探放水技术，成功的将3002（北）采空区内大量积水疏放干净，确保了3004（北）煤巷工作面的安全掘进以及后期3004（北）采煤工作面的安全回采。%This paper focuses on the application and study of the technology of detecting and discharging water from goaf area with rock lane to detect and discharge the water from the Hebi Coal Eighth Coal Mine 3002 (North) water area. Through the implementation of the technology of detecting and discharging water, a lot of water in 3002 (North) goaf area was successfully discharged, thus ensuring the safe boring of 3004 (North) coal roadway working face and the safe recovery of later 3004 (North) coal working face.
