The characteristics of narrow and closed structure and complex geological conditions are that professional support technology (such as steel arch support) is adopted to ensure safety. Roadway ponding mainly originates from geological structures (such as aquifers and fault cracks), human factors (such as roof collapse and unsealed drilling) and surface water penetration, and can cause the roadway to be flooded, equipment to be damaged and even water to be permeated, so that personnel safety and production efficiency are seriously threatened. Generally, when a worker pumps and drains accumulated water, the pumping and draining efficiency and water level control of the accumulated water are mainly concerned, and monitoring and analysis of water quality parameters are omitted.
