Abstract: In order to solve the contradiction between the protection of water resources and mining, according to the classified research result of aquifer-protective mining (APM) conditions in shallow coal seam during normal mining process of 32202 longwall coalface of Bulianta mine in Shendong mining area, the min-ing height is determined to be below 5.3 m and large power of hydraulic support and large power and high reliability equipment are selected to ensure that advance rate of coalface is greater than 15 m/d after demonstrating APM mechanism and feasibility. After coalface mined, the water level observation of ground well shows that the water level of No.10 observation well located in the middle of the coalface stabilizes gradually after about 25 days and relatively increases 0.66 m compared to the ground while the water level of No.18 observation well near the tail entry stabilizes after about a month and relatively reduces 0.87 m compared to the ground. The Quaternary loosened aquifer is less affected by the variation of water level and the main plant species of the surface can grow normally. The industrial test shows that aquifer-protective mining technology which features fast forwarding in the long wall coalface can be successfully applied in suitable geological conditions. What’s more, the research can provide reference for ecological environment construction and increases coal recovery rate for the shallow seam of mines with our country.
