The invention provides a coal cutter virtual-real fusion positioning scheme based on a laser radar. The coal cutter virtual-real fusion positioning scheme comprises a bottom layer data processing system, a data correction system and a virtual reality system. Two two-dimensional laser radars, a tilt angle sensor and a speedometer which are installed on the coal mining machine are used for collecting attitude data of a support and the coal mining machine, and relative position information and absolute position information of the coal mining machine in a working face are obtained through resolving modules arranged in a fine positioning system and a coarse positioning system after the attitude data are corrected through a data correction system. Simulation motion of a cutting propulsion process is realized in a virtual reality environment, position information of the coal mining machine is obtained through man-machine interaction, and judgment of confidence of a positioning result is given at the same time.
