Roof sandstone water is mainly reserved, weak recharge, and easy drainage feature. We take preemptive water drainage measures. It improved digging construction environment, reduced the threat to safety and production. On the mining face, we first explore and then drain, construct drainage channel to lower the water level, eliminate threats to face, and lay the foundations for mine safety.
