摘要： A mine field layout method suitable for fluidized mining of coal resources is provided. A main shaft and an air shaft are provided in the mine field, the bottom of the main shaft is located in the shallow horizontal coal seam zone, and the bottom of the air shaft is located in the deep horizontal coal seam zone. The horizontal main roadways are arranged at two boundaries along the strike of the coal seam, and inclined main roadways are arranged at two boundaries along the dip direction of the coal seam. Connecting roadways are located inside the mine field and are in communication with the horizontal main roadways. In the coal mining stage, the coal resources can be converted into the fluidized energy product and/or electricity by an unmanned automatic mining machine. The energy transmission pipelines arranged in the main shaft and the roadways transport the fluidized energy product and/or the electricity to the ground. This mine field layout reduces the number of shafts and roadways for coal lifting, transportation, drainage, ventilation, and power supply. Therefore, the construction and maintenance costs of the roadway are reduced. In addition, there is basically no residual coal pillar left in the mine, and the recovery ratio is high.
