Abstract

The invention relates to equipment for underground mining of minerals. The goal is to increase the efficiency of the support on inclined formations by reducing the exposure of the roof and increasing its stability. The unit-mechanized lining includes sections that have overlaps with the front brackets. Guiding beams (NB) 2 are located between the sections. The front ends of the NB 2 are pivotally connected to the intermediate beams (PB) 3 of the conveyor 4. The rear ends of the NB 2 are connected with the help of hydraulic jacks, advances 5 and 6, located in NB 2. In the horizontal plane, PB 3 are located at an angle to the longitudinal axes of NB 2 and 657 (Л О5

The unit-mechanized lining functions as follows,

In the initial static position of the mechanized support section, the location of the bottom,

The device also provides additional autonomous stability of sections when they are shifted, since each section moves directionally and stably in the space between the combined guide beams with oriented autonomous directions between the roof and the soil and the bottom is stable, due to the step size of the slide the support sections are interconnected with each other and with the conveyor according to the set-aggregative principle — by means of hydraulic jacks, advancing the combined guide bars to and the base of the conveyor with prombalki and protrusions.

The harvester, moving along the conveyor belt mainly from the bottom up, carries out the excavation of the next strip of the reservoir mineral, for example coal. At the same time, due to the diagonal location of the jab at an angle j- relative to the dip of formation B, the coal driven off and submerged in the combine is transported by the conveyor along the bottom. In the case of squeezing the formation or its collapse, as well as rolling the pieces of coal along the conveyor, they roll and press down to the bottom, dramatically reducing the speed of movement, which ensures the safety of the wellbore space during the excavation of minerals on inclined formations.

As the combine moves, the mechanized lining sections are successively unloaded, moved to the face, and bulged between the top and bottom of the formation. FIG. marked the position of the 26 bases of the sections after shifting

As all sections are moved, the front extension of the conveyor is carried out along the entire length of

The proposed unit-unit mechanized support for inclined mineral formations provides an increase in the efficiency of complex-mechanized working faces on inclined formations with a diagonal location of the bottom. The device provides autonomous, without any external control actions from the operator or a special control system, directed movement of the support sections and the conveyor base at a diagonal

The device also provides the unification of the lining sections when using them on a gentle and inclined seams with a diagonal arrangement of the bottom (except for the bottomhole formation)

In addition, the device provides the ability to use complete-modular mechanized lining in another face, for example, in the right, which corresponds to a mirror image (FIG.), While the upper bevels 9 and the lower bevels that are symmetrical to them, as well as the steps of the guide beams automatically change places. with preservation of the qualities
