The invention relates to the mining industry and can be used during transport of rock from the tunnel face.

A well-known method of transportation of rock mass from the face, including the gasket through the mine workings to the track, feed him cars and their subsequent loading of a mass of rock and hauling trucks winch or horses. This method is non-productive as modern harvesters "cut" per shift significantly more coal than can take the trolley.

There is a method of transportation of rock mass from the face using a scraper conveyor. The rock mass is fed from the harvesting machine to a conveyor and is "pumped" from the bottom, and in advance of the face conveyor is increasing, i.e. make it a breakout. This method is time-consuming, because, as the capacity of the pipeline, it becomes quite heavy and long, quickly wear out, requires a lot of energy due to friction of the chains and scrapers (Mining and underground construction. Part III. Construction technology of horizontal and inclined mine workings. Experience in the construction of horizontal mine workings. http://bibliotekar.ru/shravochnik-71/118 .htm).

There is also known a method of transportation of rock from the tunnel face using two belt conveyors - stationary and suspended. Art is transient pipeline is located on the grounds of generation, above it is the loader that is associated with the harvester and moving on to the monorail, suspended from the frames of permanent lining. Due to "overlap" material handler on the stationary conveyor is provided the opportunity to promote slaughter at a distance of 60 meters without breaking the conveyor chain. When promoting the slaughter of over a distance of 60 meters stationary conveyor lengthen. The disadvantages are that the material handler clutter the faces and does not fit into hypsometry (forms) develop, because the conveyor belt should be straight. In addition, the pipeline it is necessary to build the entire length of vyrobky, which is long enough (Mine and underground construction. Part III. Construction technology of horizontal and inclined mine workings. Experience in the construction of horizontal mine workings. http://bibliotekar.ru/shravochnik-71/116 .htm).

The closest to the invention is a method of transportation of rock from the tunnel face, including the loading of the rock mass in the vessel to transport with loading facilities, as containers for transportation of rock mass using the trolley, served on laid through the mine workings to the track, with their subsequent loading of a mass of rock and hauling of electric trolleys in combination with maneuvering winches (Mine and underground construction. Part III. Construction technology of horizontal and inclined mine workings. The main processes in the construction of the chamber openings. http://bibliotekar.ru/shravochnik-71/118 .htm). This method is non-productive as modern harvesters "cut" per shift significantly more coal than can take the trolley.

The objective of the proposed method is to improve the effectiveness and simplicity by eliminating expensive equipment, resulting in increased performance.

The task is solved in that the method of transportation of rock from the tunnel face includes alternate supply in the loading area of the containers for transportation of rock mass, loading of the rock mass in the vessel with loading facilities and their transportation from the face. In contrast to a container trolleys in the proposed method as containers for transportation of rock mass using the packaging and transportation of these loaded containers is carried out in limbo on the monorail, installed in the upper area of the face.

In private versions of the method can be used Tara capacity, the geometry of which allows their compact styling prior to submission to the loading area, made of plastic or other soft materials.

Thus compactly folded capacity to supply the mobility of the load can be suspended on the monorail or laid under the monorail.

Various embodiments of containers.

You can use containers in the shape of the Cup and to feed into the loading area is nested into each other.

You can use folding capacity, prior to submission to the loading area is folded and hung on the monorail, which in-turn is fed into the loading area spread.

You can use as containers of soft bags.

The proposed method provides significantly better performance in comparison with hauling trucks as a lump sum at the bottom can be designed for the loading capacity is significantly larger total volume.

In comparison with the conveyor means in the proposed method the equipment is concentrated near the bottom, with all the development-free equipment. Reduction of the consumption of the equipment used and the complexity of its installation. Throughout its long production remains one of the monorail, present in any case to ensure the delivery of people and materials.

This method can be used in any hypsometry slaughter, because the monorail does not require straightness either in vertical or in horizontal planes, which increases the performance of this method.

The method also provides security, because PR is "packaging" of the rock mass paleodelta greatly reduced and there is no typical conveyor transport of peresypav.

The invention is illustrated by drawings.

1 schematically depicts the loading of the rock mass in the tank-glasses.

Figure 2 schematically depicts the loading of the rock mass in folding capacity.

Figure 3 schematically depicts the loading of the rock mass in the "soft bag".

The method can be carried out as follows.

Example 1

To combine 1 monorail 2 filed compactly stacked glasses 3 (figure 1) or a cylindrical tank 4 (figure 2). Glasses 3 or folding of a cylindrical tank 4 lead in working condition as follows: glasses 3 are separated from one another, and each of the cylindrical containers 4 straighten using a folding bar 5, is placed in the tank 4. With the help of a loader 6 average rock mass, carry out the loading of the rock mass in the 3 cups or containers 4, bring the 3 cups or containers 4 to the destination, unload them, and then carry out the compact stacking of containers 3 or 4, hung them on the monorail 2 and transported them to the combine harvester 1. The cycle repeats.

Example 2

To combine 1 serving compactly stacked containers in the form of soft bags 7, arranged in a set of 8 (figure 3). Are preparing containers for loading, separating one bag 6 from the other, then use the loader 5 hang each bag 6 on the monorail 2, carry out the loading of the rock mass in the bag 6, Tr is sportabout them to the destination, unload them, and then carry out the compact stacking of the bags 6, and transported them to the combine harvester 1. The cycle repeats.

In examples 1 and 2, issuance of filled containers in the "loaded" position performs standard monorail disalvos. Turnout compactly set (empty and loaded containers is performed on a periodic traveling.

The inventive method improves the performance of the transport process due to the absence of expensive equipment, the possibility of using faces with any hypsometry and the optimum ratio of the occupied volume of the vessel for loading rock mass (tare) in a compactly stowed (folded) condition and capacity of the harvester.
