Fifth coal mine, mine shall be in accordance with the unit's water situation, to fulfill the needs of water prevention and control professional and technical personnel, complete special survey water equipment, the establishment of specialized survey water operations team.
Hydro-geological condition is complicated, very complicated coal mine, mine, except in accordance with the first paragraph of this article shall, should also set up a special control institutions.
Sixth Strip coal mine, the mine shall establish and improve flood control and responsibility, disaster prevention and control technology of management system, flood forecasting systems and water troubleshooting, system of governance.
Seventh coal mining enterprises, mine water control of the unit shall be compiled long-term and annual plans, and their implementation. Article eighth coal mine, mine mine field within and around regional hydrogeological conditions are not clear, effective measures should be taken to identify water.
In front of a water hazard identified, non-extractive activities.
Found mine flooded when shall immediately stop the flood threat of mining in the region, the withdrawal of workers to a safe location, effective security measures, analysis finds water causes.
The Nineth coal mining enterprises, mine water prevention education and training of workers to ensure employees have the necessary knowledge of water control, improved water control work skills and the ability to resist floods.
