[0030] like Figure 1 and Figure 2 As shown, the utility model provides a comprehensive mining face equipment 110 test system, including: a studio 100, a display screen 200 and a controller 300, the studio 100 is used to install the comprehensive mining face equipment 110; the display screen 200 is installed in the window of the studio 100, the display screen 200 is made of transparent material, and the mining height curve of the comprehensive mining face equipment 110 and the cutting template curve of the comprehensive mining face equipment 110 are displayed in real time on the display screen 200; the controller 300 is electrically connected to the comprehensive mining face equipment 110 and the display screen 200. The controller 300 displays the information of the comprehensive mining face equipment 110 through the display screen 200, and the controller 300 controls the operation of the comprehensive mining face equipment 110.

[0031] That is to say, the staff is placed on one side of the display screen 200, and can observe the comprehensive mining face equipment 110 in the studio 100 through the transparent display screen 200, and can well observe the specific working conditions of the comprehensive mining face equipment 110, and find problems in time and make correct adjustments.
