POWERED TUNNELING AND STOPING COMPLEX (UNIT) Russian patent published in 2001 - IPC

FIELD: mining industry; applicable in driving of mine workings and stoping. SUBSTANCE: powered tunneling and stoping complex includes support units, each of which has guard, roofing wit canopy, hydraulic props and base. Support units are connected with common frame and with base beam by means of advancing hydraulic jacks. Base beam consists of interconnected sections. Complex also includes combine actuating member with turning device, dust suppression means, transportation devices, power station and control panel. Frame is telescopic and consists of parts interconnected by means of tongue-and-groove joints. Base beam is hinged to frame extensible part. Turning device of actuating member is installed on base beam. Support units located at roof and floor of bed are mirror combined in vertical plane. Frames may be hollow and provided with hydropneumatic elevators and inlet ports for dust suction. Turning device of actuating member may be installed on base beam for motion. Base beam may consists of lengths whose width equals support unit width and may be provide with rack of combine propelling device. Turning device of actuating member my be fixed to one length of base beam. Actuating member may be made with boom whose hollow part has screw conveyer or hydropneumatic elevator. Roofing canopy may be provided with brackets for fastening of drilling machines for roof bolting and with mounting seats for installation of transportation devices, for instance, gathering arms. EFFECT: extended field of complex application, higher productivity of powered stoping breakage faces, increased advance rate, unification of mining equipment. 6 cl, 13 dwg
