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.

摘要： A mining machine applicable to fluidized mining and a mining method therefor are provided herein. A microwave transmitting mechanism, a liquid jet drill rod and a cutter-head are arranged at the head of a first excavation device of the mining machine. The ore body in front is first processed by the microwave transmitting mechanism and the liquid jet drill rod to reduce the strength of the ore body, which facilitates subsequent mining of the ore body, lowers the hardness requirements of the cutter-head, and reduces the wearing of the cutter-head. With this mining machine mining the ore body, the mined ores can be directly converted, under the ground, into resources in the easily transportable form, without transporting the ore to the surface for conversion, which saves the cost of transporting the ore to the surface.
