The invention relates to mining. Designed for mechanization of processes when conducting horizontal, inclined and VOUT drilling modules and transport subsystem, consisting of loading and transport modules, usually performed in separate machines. Such sgpm reduce the time spent on the operation of loading rock mass. The peculiarity of the considered sgpm is that loading of the rock mass is a parallel operation of two loading machines (Loading machine in mining industry/ C. D. Irasci, O. P. Ivanov, A. S. Logvinov and other Novocherkassk, CUI, 1978, - S. 13, S. 16, Fig. 2.8 b). Disadvantages sgpm: the sequence of operations of the driving cycle; the impossibility of carrying out operations during the airing of production; provide a reliable protection working bottom space from possible fallout rocks or collapse of the great masses of the roof framing.

The closest to the overall layout and process flow of the holding and transportation of rock mass on the ongoing development is sgpm (Gorbunov C. F., eller, A. F., Buffoons C. M. principles of design burocracia tunneling systems. - Novosibirsk: Nauka, 1985, - S. 113 - 114). Considering sgpm consists of two mechanized lining, which acts as a basic element. Unconventional frame, driving trucks and power. The shields are moved by hydraulic cylinders. For this support arches set in a special chute. Each element of the guides at the junction of the sections are interconnected elastic elements present in the cavity of the guides, with the possibility of longitudinal movement, allowing the sections to move in two planes. Loading of the rock mass is in the trolley, moving through the Central part of the output.

The advantages of this sgpm are: partial alignment of the drilling operations of the set of holes and loading of the rock mass; a single design, which mechanized basic operation of the driving cycle with minimal movements in the development.

The disadvantages include the following: inability operations during the airing of production; the use of trolleys for transportation of rock mass lead to additional time spent on the exchange of trolleys.

The most progressive schemes sgpm are schemes with loaders. For example, with wedge loaders for bulk lumpy rocks (see author's certificate N 1684188, class B 65 G 65/00, 25/08 Conveyor for transportirovaniia loading module, for example, the bucket, for pollachi rock mass to the material handler.

The aim of the present invention is to increase productivity, increase the speed and level of mechanization of work when carrying out horizontal, inclined and rising mining browsercam way.

These objectives are achieved by the application of the system of mining machines, providing a combination of operations of the rock mass, drilling blast holes for anchors or bottom and erection anchor or polaramine-anchor lining puff, the combination of loading and ventilation output. In addition, the proposed system of mining machines eliminates the use of additional loading module for loading rock mass on conveyor. The system of mining machinery consists of two mechanized roof supports, drilling modules and handling subsystem, implemented on the basis of the V-loader, comprising sequentially arranged sloping reception with wedge elements and the inclined discharge portion, characterized in that the receiving portion of the loader is equipped with expanders in the form of wedge elements along his side is blenny inside a stationary wedge elements. Two-piece shield support provided with a breathtaking device, made interoperable with expanders material handler at the time of advancing roof support.

The material handler is located along the axis of the workings, and drill modules are arranged symmetrically with respect to the material handler. This equipment provides mismanaging work of drilling modules and handling subsystem.

The reception part of the loader allows you to work in the mode srivanalai that allows you to start the cleaning of the rock mass from the bottom till the end of time airing output.

The combination of the operations of loading rock mass and drilling blast holes for anchors or bottom is due to the fact that the cargo is being loaded by the loader, and drilling holes - drilling modules. All of the above equipment is in development and has the ability to combine their functions in time and space.

The proposed system of mining machines allows to achieve a high level of mechanization of all operations of the driving cycle, increase productivity and increase the rate of penetration preparatory myrabo the availability of powered roof supports, drilling modules and handling subsystem, implemented on the basis of the V-loader, comprising sequentially arranged sloping reception with wedge elements and the inclined unloading part. The reception part of the loader is equipped with expanders in the form of wedge elements along the lateral sides of the loader, with the ability to move perpendicular to the axis of the loader by means of hydraulic cylinders mounted inside the stationary wedge elements. The loader allows the user to work in the mode srivanalai. Two-piece shield support provided with a breathtaking device, made interoperable with expanders material handler at the time of advancing roof support.

The invention is illustrated by drawings.

Fig, 1 shows a layout diagram of the system of mining machinery for carrying out horizontal, inclined and rising mining Borovlyany way, consisting of cargo transport subsystem, executed in the form of wedge material handler 1, consisting of consecutive admissions with 2 mobile 3 and 4 fixed wedge elements and NaClO the Atami 9.

Drill the modules are moved along the guide beam 10, mounted on two mechanized roof supports. The loader allows you to work in the mode srivanalai.

In Fig. section 2 presents the material handler according to section a-a in Fig. 1.

The principle of work of the proposed system of mining machines next.

After charging, blasting holes and ventilation starts cleaning the rock mass on conveyor 1. When the rock mass is removed along the entire length of the loader, begin their work ureterocele V-6 material handler, they served the rock mass along the entire length of the wedge material handler at the receiving part 2 wedge material handler.

When a portion of rock removed, begins drilling downhole drilling modules 7.

After harvesting, the rock mass is advancing mechanized roof supports 8. Together with mechanized support moves the loader as follows: Widener V-6 material handler apart and the hooks 9, located on the powered roof supports 8, moving the supports to move the loader (Fig. 3).

After the support is moved, the continued drilling of bore-holes.

System gornoprohodcheskogo, made on the basis of wedge material handler, comprising sequentially arranged sloping reception with wedge elements and the inclined discharge part, wherein the receiving portion of the loader is equipped with expanders in the form of wedge elements along its sides can be moved perpendicular to the axis of the loader by means of hydraulic cylinders mounted inside the stationary wedge elements, and two-piece shield support provided with a breathtaking device, made interoperable with expanders material handler at the time of advancing roof supports.
