    摘要: Roofs of underground excavations are supported by forming sheet-material elements into tubes whose diameter can be varied by changing the overlap between the longitudinal edges of the rolled-up sheet material, standing the tubes upright to bear against the roof and the floor of the excavation, and filling them with hardenable material in flowable condition which, after hardening, will form a roof-supporting column.

    摘要: Process and device for controlling longwall shearing and heading machines along a cut horizon between coal and rock. The horizon is produced by a cutting tool arrangement attached to the machine and followed by a sensor which distinguishes between coal and rock. The values measured by the sensor are converted to control impulses which guide the cutting tool in the cut horizon. Mineral samples are taken, continuously or at short distances apart, behind the cutting tool arrangement, and the sample material is analyzed in the sensor. The result of the analysis is compared with a standard value and the deviation from the theoretical value is used as the value of the control impulses.

    摘要: A method of single-entry mining of coal and analogous minerals is disclosed, which permits substantially 100% extraction of the coal or other mineral in a seam. All operations are carried out under hydraulic steel roof supports adjacent the mine face; farther back the roof is supported by non-yielding cast-in-situ pillars of quick-setting concrete rather than coal pillars or other supports. Mining machinery for these purposes is also disclosed.

    摘要: In hinge tracks with rubber mountings (5) in which rubber-lined tubular steel bushes mount track pivot pins (20), the pin ends are usually provided with screwthreaded projection portions so that the steel bushes (10) are motion-free braced relative to each other and relative to the track pivot pins (20) by means of nuts. In order to improve the useful life of the rubber mounting (5) and reduce maintenance, a rubber-lined spreadable bush (10) with at least one dividing gap (11) is proposed instead of the tubular bush. The internal width (25) of the bush (10) which is pressed into position is less than the diameter (27) of the track pivot pin (20). The inserted track pivot pin (20) expands the bush (10) which is pressed into the chain link member (1). In that case the track pivot pin (20) is braced in the bush (10) and is fixed in its longitudinal direction by frictional engagement and in the peripheral direction by frictional engagement and/or positively locking engagement. The screw for bracing the bushes (10) are eliminated and an increase in the rubber mounting surface is achieved by virtue of using the screwthread space of the screwthread arrangement. That affords an increased service life for the rubber mounting in a maintenance-free design configuration.

    摘要: A belt-type Caterpillar for track-laying vehicles and snowmobiles, incorporating individual replaceable belt segments, in which each belt segment incorporates a base member consisting of rubber including tensile-loaded inserts which encompass a traction or tie anchor transversely supported within the rubber in the region of the connecting locations for the belt segments. The connecting locations which are formed as hinge members vulcanized into the belt segments include tubular sections with inserted tubes or track pins, as well as arms arranged at a lateral spacing from each other, whereby the arms retain the tie anchor which is formed as a connecting pin or bolt. The inserts consist of at least two endless fabric bands or webs arranged at a spacing adjacent each other, the arms terminating proximate a nonelastic bending region of a rubber or track dog, or transversely stiff traverse, and in which the hinge members possess laterally arranged arms.
