s2, converting the tunneling progress of the tunneling machine into coordinate data, wherein the conversion method comprises the following steps:
X＝X 0 +JX*SIN(θ)
Y＝Y 0 +JX*COS(θ)，
wherein: (X) 0 ，Y 0 ) The initial point coordinates of the roadway; JX is the propulsion progress, and the position data of the heading machine is obtained; θ is the gradient of the working face, and is obtained through attribute parameters of the roadway; (X, Y) is the current tunneling position coordinates;
s3, feeding back and displaying the (X, Y) position to the mine map, wherein the specific method is to replace the initial coordinate of the roadway with the (X, Y) coordinate, so that the rendering and displaying of the two-dimensional engine of the roadway in the free drawing area are realized, the roadway length is automatically extended according to the position of the heading machine, and the propelling progress is automatically adjusted according to the position of the coal mining machine.
