Abstract

The invention relates to mining promet for mining steep seams of high-power coal in a fall with the collapse of the goaf. The purpose of the invention is the expansion of operational capabilities. Mechanized lining contains several rows of sections of the same type, each of which has an overlap 2, a hydraulic post 5 that is hinged to it, a base 4 rigidly connected with an overlap by means of supports 3. The base 4 is made with a window in which the hydraulic post 5 is placed. The supports 3 are equipped with hydraulic cartridges 6 for spreading into adjacent sections. Overlap 2 is connected along the longitudinal axis using fingers 7 and their fixing elements, and along the transverse axis plates 8 with openings in which fingers 7 are placed. This connection of the support sections allows you to quickly and reliably change the width of the support depending on the thickness of the formation , to work under the lining at the same time with several mechanohydraulic combines. 3 il.

Description

The invention relates to the mining industry and can be used in the development of steep seams of high-power coal in the fall with the collapse of the developed space.

The purpose of the invention is the expansion of operational capabilities.

Figure 1 shows a General view of the lining, section aa in figure 2; figure 2 - section bb in figure 1; on fig.Z - view of the lining section in a perspective view.

The mechanized lining for mining powerful steep seams of coal includes interconnected along the longitudinal and transverse axis of the lining of section 1. Each section contains an overlap 2, to which two supports 3 are fastened with bolts

bolted to the base 4. The overlap is reinforced with stiffening ribs on the inside. A hydraulic post 5, made telescopic, is attached to the ceiling using a ball joint. The supports are equipped with hydraulic cartridges 6 for thrusting into adjacent sections. In each row, the overlap 2 is interconnected along the longitudinal axis of the hinged fingers 7 and the locking elements. Along the transverse axis, the overlapping 2 rows are connected to each other by a hinge with the help of plates of 8 s. holes in which fingers are placed. The bases 4 are provided with windows for accommodating hydraulic posts 5, and the supports are provided with windows 9 in which the pressure main is laid. The ventilation and passage of the attendants is carried out according to

pressure main. A flexible overlay is laid on top of the sections.

Depending on the thickness of the formation, the required number of rows of sections is accumulated.

The unit is processed in a downward order. Under the proposed support, coal is taken out of the ditches using mechanical combi-type combines of the type K-56 MG, the ditches are drawn at an angle of 5-7. The coal repulsed and mixed by the combine's working body is transported by gravity along the grooves to the coal-burning stove, after the coal has been dredged, the hydraulic stands are pushed along by the hydraulic posts and the flooring is the same as both previously located in the support sections. After excavation, the ditches for the entire length of the block work out the rear sight. Working out of the rear sight is possible either by the return stroke of the combine, or after the turn of the combine upstream. After the ditch has been taken out and the rear sight is removed, the gutters are dismantled and, reducing the rack, lower the whole row of supports. Hydraulic cartridges are in an open position and only when lowering a number of supports in the case of wedging sections are reduced, which facilitates the landing. This removes all chips from

lying to the front of the board, with a height of 2.0-2.5, after which the next chips are taken out. The proposed support provides ventilation at the expense of general depression, as well as due to the increased flexibility of support, it is possible to ensure the complete extraction of coal at variable hypsometry formation.

Fo rmu l and z o b r e te n Mechanized roof support for machining thick steep seams, including sections connected along the longitudinal and transverse axis, containing overlaps and hinges connected to them that, in order to expand operational capabilities, each section is provided with a base rigidly attached to the overlap by means of supports equipped with a hydropatron for spreading into the next section, and made with a window for accommodating a hydraulic post; their sections along the longitudinal axis of the support are made in the form of fingers and their fixing elements, and along the transverse axis in the form of plates with holes in which the fingers are placed.
