The invention relates to mining and can be used in the development of steep coal seams stripes in the fall.

The purpose of the invention is to expand the operational capabilities, increase productivity and safety of work on the Sh. IET plot when mining steep coal seams in the fall bands. FIG. 1, 2 shows a complex, a general view; in fig. 3 — support of the complex mate; in fig. 4 — borehole section, side view.

The complex consists of one working cleaning unit (excavation machine) 1 and a second cleaning unit 2, located in re-assembly on a new strip, cut-in mechanized lining of furnaces 3 and a niche-cutting unit 4. Working cleaning unit 1 from the coal-fired furnace 5 is equipped with a fixture 6, consisting of a section of the main 7, equip- ing, forcibly adjustable in mosh, bearing and direction of the formation with an overhang, itnaya fence 8, and an auxiliary section 9, interconnected by means of hydraulic jacks of movement 10.tim 6 kinematically coupled to the cleaning machine 1 and furnace 3. The mechanized bolting unit 4 Nishe- threaded complex equipped with an additional section 11, the goaf side opirayusheys 12 mounted on the extreme portion 13 in the shield support assembly 2 peremontiruemogo purification.

The preparation of the site for the development by the complex consists in passing a split (coal-discharge) furnace 5, mounting mechanized lining of furnaces 3 therein, and also using a mounting niche 14 using a niche-cutting unit 4 and installing cleaning switchboard unit 1 therein. oven 5 is held only once. For the subsequent lanes, a ventilation furnace 15 is detached from the coal-fired detachable sections of the mechanized support from the coal massif. The installation of the niche-cutting unit 4 also takes place only once in the mounting niche 6-7 m long in preparation of the section, and for the subsequent lanes this unit holds the niche 6-7 m longer than the length of the mounted cleaning unit. The complex contains shield lining 16 and a conveyor belt 17 connected with lashing mathnik-telescopic levers 18 with feed jacks 19 and swings 20. To enable reassembly of the lining sections of the furnaces in the inter-racks of the unit, the bottom rails of each section are fitted with rigidly attached bases protective covers 22 in the form of a U-shaped stand with rounded corners. On the covers of the 22 sections of the suspension 23 are placed the supports of 24 telescopic levers 18. Shortened Kutkovye

guard sections 25 are provided with protective covers also above hydraulic posts 26, which are located at the level of the bottom sections of the remaining sections. This allows the winch cable to pull the lining section of the furnaces onto the protective covers 22 of the fill posts of the 26 Kutkov sections 25, and then lift it to the installation site in the ventilation oven. A mounting device 27 in the form of a sliding table that is forcibly moved along the dip and uprising of the reservoir relative to the Kutkov sections with hydraulic jacks pivotally connected by one ends with this table and the latter with the base of the section is placed on the fill posts of sections 25.

The operation of the complex must be organized in such a way that while the operating switchboard unit runs its strip to the height of the floor, the second cleaning unit must be dismantled, transported to the ventilation horizon and mounted in the mounting niche.

The operation of the cleaning unit for the performance of one cycle of coal excavation begins with a notch of the conveyor belt by a wave at the roof of the formation with one or two jacks, starting from the drive head. After the notch for the full stroke of the first jack of the feed, the first linear section is shifted by a step of shifting and spreading it, then a second and subsequent steps are made along the notch - along the bridge. After finishing the notch and shifting of all linear sections, the remaining bundles of coal are crushed, and then simultaneous shifting with thrust of the base sections and their spreading. After that proceed to the rewiring section of the lining of the furnaces. For this, the section is unloaded, folded into the transport position and retracted under shield shield. Immediately after dismantling the lining section of the kilns, the lining of the mates is moved to secure the side rocks in this place. Then, the furnace securing section is moved in the inter-rack space of the cleaning unit to the ventilation oven and is installed in this furnace. To reduce the time for the implementation of one cycle, the processes of cutting the conveyor belt, shifting the linear sections and moving the lining section of the furnaces under the unit can be combined in time.

The work on the mounting niche is as follows.

Directly after moving a low-cutting unit to the slider of the advancement, section-by-section delivery and installation of shield support sections of the reassembled cleaning unit under the protection of additional section 1 is carried out. Processes for excavating coal through a cutting assembly and delivering shield support panels can also be combined in time.
