as with rear guide means which are all pivotably fastened to the plough body basic element 20 a 20 b the ploughing tools 69 of both plough body basic elements 20 a 20 b are once again detachably fastened to a tool carrier 61 which can pivot relative to the plough body basic element 20 a and 20 b about a in this view non discernible pivot pin the two plough body basic elements 20 a 20 b are connected with the same fastening means 40 to a plough body of minimal width and thus minimal working height the depth of the relatively narrowly constructed mining plough amounting to roughly half the working height a driving block can be mounted on one of the fixing eyelets 92 for the person skilled in the art numerous modifications emerge from the preceding description which modifications shall fall within the range of protection of the appended claims in a further non represented embodiment a mining plough guided on both sides on guide bars or the like lying one above the other could also consist of a one piece plough body element all the advantages of being able to convert the same plough body to different working heights would then however be lost further while considerable emphasis has been placed on the preferred embodiments of the invention illustrated and described.
