in front of the feeder hopper 40 for a distance of at least 20 feet the dipper 50 can also be raised a substantial distance for excavating a bank 59 for example the continuous mining machine 10 can have the dipper 50 raised to a height of 75 feet without undue stress the continuous mining machine 10 has been described for use with boom 45 which is of a one piece construction if desired a boom could be constructed in two parts this is described in conjunction with the embodiment generally 64 shown in fig4 similar components are identified by the same numbers as previously described in conjunction with embodiment 10 except they are shown as primed the twin booms are identified as 45 39 and 69 and although not shown will have the dual feet as described previously with respect to boom 45 and feet 42 and 43 boom 45 39 will be supported by the mounting 71 interconnected by the support 70 which in turn is connected to the mounting 72 on the frame support 27 the boom 69 is connected to the mounting 71 and is supported through the cable 73 which connects to the bracket 74 and to the mounting 72 extending from the frame support 27 another difference in the embodiment 64 is the proportionately shorter feed conveyor 66 for feeding material to the crusher 17 it also has a hopper 67 to receive material from the dipper 50 still another difference in this embodiment 64 is the outlet conveyor 61 having a different form of load side 62 but a similar return side 63 it will be noted that a standard twin or dual.
