Apparatus for introducing stowing material into cleared-out spaces of an underground mining working

摘要

The apparatus comprises supporting mounts A, AK arranged next to one another and a blowing line 2 which is composed of individual length portions LA1, LA2, LA3, etc. and which is fastened to blowing walls 12, 12a, 12b positively guided on the roof-member portions of the supporting mounts A, AK located on the same side as the stowing. The length portions LA1, LA2, LA3, etc. are longitudinally displaceable and vertically shiftable relative to the blowing walls 12, 12a, 12b extending parallel to them. The length portions LA1, LA2, LA3 etc. can be shifted jointly with the blowing walls 12, 12a, 12b transversely relative to the longitudinal direction of the longwall face. <IMAGE>
