Description

one

The invention relates to equipment used in the mining industry for discharging ore from a cleaning space in floor-breaking systems with face release.

A device for producing and loading ore is known, comprising a body made in the form of a shell mounted on a frame with a reception in the upper part, covered by a movable gate of an arched shape, the longitudinal guides along which the shutter moves, enter the zone of the blocked opening 1.

It is also known a device comprising a housing, a movable slide with guides, a movement mechanism, longitudinal rods fixed on the inner surface of the housing.

A disadvantage of the known technical solutions is the difficulty of airing and dust suppression in a dead end, which reduces sanitary and hygienic working conditions.

The purpose of the invention is to improve the working conditions.

This goal is achieved by the fact that a device for ore production, including a housing, a movable gate with guides, a movement mechanism and longitudinal rods fixed on the inner surface of the housing, is provided with a pipeline with a fan, the longitudinal rods are hollow and

10 communicates with the pipeline, and in the gate channels are made with nozzles installed therein on the inner surface of the gate and means for connecting the nozzles to a water supply source.

The drawing shows the proposed device, a longitudinal section, I The device for the production of ore has a body 1 of arched shape with an opening in

20 of the upper part, movable pickup 2 with hydraulic cylinders C, installed in guides 3. Inside the case there are fixed rods 5 with a mechanism of 6 perr, grip of hydraulic cylinders. The vertical hydraulic jacks 7, the horizontal hydraulic cylinders 8 and the base 9 form the mechanism for moving the device o Moving shutter 2 is reinforced with longitudinal 10 and transverse hollow stiffeners. Inside the longitudinal ribs, piping 11 is installed, terminated by nozzles 12, and on the other side the piping is connected by a manifold 13, Which is connected to the water supply by a flexible hose. The longitudinal rods 5 are hollow and connected. interconnected by a pipeline 15 connected to the ventilation system.

The operation of the device is as follows. -

The device is installed at the dead end of the end face at a distance from the end face equal to the thickness of the ore layer being fought off. By vertical jacks 7, the body 1 is raised above the base 9 and spreads out in the working from axial displacement, fixing the interface of the cleaning working with the face. Next, the ventilation system is turned on, and depending on the ventilation pattern, fresh air is supplied to the face or it is sampled, and the central heating system is turned on, after Mego, the ore is collapsed. The crushed ore forms a pile inside the hull. By turning on the hydraulic cylinders k, the bolt is inserted all the way into the ore. Inside the hull 1, the loading machine enters and cleans the ore portion that has been released. As the ore is loosened before the toe of the gate, the latter is introduced to a greater depth, blocking the outflow of ore. After the stems of the hydraulic cylinders 4 are fully extended, their stop is intercepted by the interception mechanism 6.

After cleaning the released batch, the Loading Machine is retracted to a safe place and the shutter is completely retracted inside the hull. As the shutter is pulled out of the escarpment,

the next portion of ore. This includes irrigation and ventilation systems.

When the discharge of the entire layer is completed, the irrigation and ventilation crucible in the device is turned off and the device moves to a new location by the size of the collapse step of the entire layer. This is done in the following sequence. The spacer Bejj of the hydraulic jacks 7 is removed and the housing 1 is lowered onto the base 9. Then the hydraulic cylinders 8 are turned on, which move the housing 1 along the base 9 to the stroke of the rods, then the hydraulic jacks 7 rise above the base 9 and shorten the hydraulic cylinders 8 to the base under the housing. By repeating these operations, the device is moved to the required distance.

The use of the proposed device makes it possible to improve the sanitary and hygienic working conditions in the downhole zone with face release.
