The hollow rock bolt 10 is shown inserted in the borehole 11 in the rock formation 12 * The channel 13 ₉ which leads through the interior of the rock bolt " can either be used as a vent for the borehole 11 or as a channel for the mud" with respect to the surrounding Gestelnsformation 12 14 has a wedge in threaded engagement with the bolt rod 10, as well as support members 15 xm & iodine These parts are disposed on opposite sides of the Bolsenstange and the wedge 14 is disposed between;

If the continuity of the channel formed by the bore 13 in the zen rod is preserved, the bracket is provided with shoulders 18 and 19 and a central bore 20. Shoulders 18 and 19 create a gap between the central part of the Bracket and the end 21 of the bolt rod, whereby a channel is obtained which extends laterally in opposite directions ¹ in connection with the bore 13. The hole 20 under = supports this effect in that it forms a gleichacbsigem channel, and it is preferable that both of these assemblies ₉ are present. However, one of the arrangements · = »can only fulfill the g-.vsck ο The combined lateral and equiaxed channels lead to a better discharge of the sludge and further reduce the possibility that the channel could be" blocked "by rocks or the like .

Bas hole 20 should be slightly smaller than the channel 13 des öes ^ einsbol2iens, in order to "diminish the possibility - that a foreign body enters the hole 20 and as
