A method of recovering particulate material from a seam of such material within the earth bounded above and below by different material which comprises the steps of positioning in mining relation to the seam a continuous mining machine having a power driven mechanism thereon for moving the machine through successive seam material cutting cycles which include an advancing movement along a mined entry within the seam in a direction toward the working face of the seam; illuminating portions of the space surrounding the continuous mining machine including portions of the working face disposed forwardly thereof and adjacent portions of the roof, floor and side walls of the mined entry rearwardly of the working face; establishing electromagnetic signals indicative of the appearance of the illuminated portions of the working face of the seam and the adjacent portions of the roof, floor and side walls; transmitting the established electromagnetic signals to a remote control station; converting at the remote control station the transmitted electromagnetic signals to a continuous picture of the appearance of at least a selected portion of the illuminated portions of the working face of the seam and the adjacent portions of the roof, floor and side walls; and controlling from the remote control station the cutting cycle of the continuous mining machine so that the material cut during a cycle is cut from the seam up to the different material defining the roof and down to the different material defining the floor based upon visually distinguishing between the material of the seam and the different material which forms the roof and floor by viewing the continuous picture provided at the remote control station and apparatus for carrying out the method.
