1, select mining: according to the easier issues first, Deep briefly after complex principles of mining; the same conditions of the coal layer, the first test drilling, sum up experience, find out the law, and gradually promote the use.
2. Partition isolation mining: use the method of leaving the coal pillars in the isolation mining area and setting up the water gates to reduce the influence range of the water inrush from the floor.
3. Change the layout of the roadway: reduce the faults, reduce the number of roadway crossings, and reduce the intersection area of ​​the roadway. The intersection of the roadway and the lower exit of the coal mining face should avoid small faults as much as possible, and the small faults should be reinforced when they cannot be avoided.
4, coal mining methods: the use of filling mining, partial mining, inclined longwall mining, layer mining; shorten the length of the working surface, improve the speed of the working surface; correctly determine the direction of the working surface.
