Abstract: 1358 west working face is the first inclined mining face of Kailuan Qianjiaying Mining Branch, which formed a waterlogged space with a volume of 9,520 m3, waterlogged elevation of -613.4 m and waterlogged depth of 7.3 m. After the completion of 1358 west working face, there was still 0.2 m3/min moving water, which posed a water hazard threat to the working face. Through the construction of pressure-limited cycle water release in 1359 west duct, the threat of water damage in 1359 west working face was lifted, which ensured the safe production of the mine and accumulated valuable experience for future water control work in coal seam mining.
