METHOD FOR CONTROLLING TIMBERING IN BED PLANE AND DEVICE FOR IMPLEMENTING THE SAME

摘要

FIELD: mechanized cleaning systems and units in developing coal beds. SUBSTANCE: method includes step-by-step moving of base beam with tails, and timbering sections with mutual lateral displacement of the base beam with tails about timbering sections. Base beam and timbering sections are displaced by turning the tails and goaf-side timbering sections about base beam to the side opposed to the direction of base beam displacement when moving. Device includes base beam comprising links and tails the ends of which are coupled to displacement hydraulic jack, and sections placed between. Tails are made in the form of two-arm levers hinged to the links of base beam. Tail ends are provided with stopping mechanism on the side of base beam. Stopping mechanism is made in the form of two-way hydraulic jack the case of which has rests. Tail end is made in the form of a fork with the rest placed in. EFFECT: improved control. 3 cl, 4 dwg
