Abstract:

Traditional classic drainage pump houses in underground mines suffer from complex structures, high construction difficulty, long construction cycles, and harsh working environments. To address these drawbacks, this paper proposes a design concept and solution for a trenchless water distribution drainage pump house. By replacing traditional water distribution tunnels, water distribution shafts, suction shafts, and suction shaft niches with a continuously arranged suction shaft, the design achieves a simpler structure, higher mechanization during construction, reduced labor intensity, shorter construction periods, and easier long-term operation. Compared to traditional classic drainage pump houses, the construction period is shortened by 1.5 months, and the construction investment is reduced by 0.711 million yuan, a decrease of 9.7%. This approach has broad applicability and potential for promotion in both coal and non-coal mines.
