In order to solve the problem of the adaptability of the 81304 working face of the Yangquan Mining group No. 1 Mine, with theoretical analysis, numerical simulation, field measurements and other research methods, the thickness of the coal seam and gangue thickness were analyzed, the strength of the coal seam and the influence of the sheet gangue, the degree of development of the coal seam and roof cracks, the dip angle and pitch angle of the working face, the number and size of the geological structure and its influence were studied, it was concluded that the risk of mining is higher if 81304 working face adopts the large mining height. Through the comparative analysis of technical and economic indexes such as retraction time, recovery rate, and equipment investment between IML and DHT mining face, it was concluded that IML was more advantageous for face 81304. According to the relationship between the height of the coal wall and the area of the coal gang, the cutting height is not higher than 4.0 m.
