WALL CONTINUOUS MINING AND CONTINUOUS FILLING WATER-PRESERVED COAL MINING METHOD, AND WATER RESOURCE MIGRATION MONITORING AND WATER DISASTER EARLY WARNING METHOD

A wall continuous mining and continuous filling water-preserved coal mining method, and a water resource migration monitoring and water disaster early warning method. In the coal mining method, a normal wall working face is divided along the strike direction into "mining-filling" and "mining-retaining" mining blocks alternately arranged; no coal pillar is retained between mining roadways in a "mining-filling" mining block (1), and a roadway with the excavation completed is filled; narrow coal pillars (10) are retained between mining roadways in a "mining-retaining" mining block (2), and a roadway with the excavation completed is not filled.In the early warning method, an infrared thermal imaging system is used for observing surface infrared radiation information of an excavation space, and predicting and forecasting a dynamic disaster such as backfill object or narrow coal pillar instability. An water resource migration monitoring and water disaster early warning system is used for comprehensive monitoring, e
