SU1229341A1 - Method of pouring muck off dump slopes - Google Patents

Description

The invention relates to the mining industry and can be used in the recultivation of overburden heaps, for example, in: laying slopes.

The purpose of the invention is to expand the field of use of dumping during the removal of the slopes of rock and soft rock dumps by providing the possibility of adjusting the angle of execution, life, and safe technology of work.

The method is carried out as follows.

When flattening the blade slope, for example, 20 m high (the angle of natural slope 35), two metal beams 115 m long are installed at an angle of 10 °, for example, 20 m between the rollers. Rollers are overlapped with removable elements 1 and 9 for example metal 10 m wide sheets that form a slope. The parameters are determined by the bearing capacity of the beams and the bulk density of the scrap. The resting angle largely depends on the coefficient of the surface friction. Nowadays there are materials with a very low coefficient of friction, which allows loads to move over their surface under their own gravity even at low angles. In the process of dumping, the overburden is poured out on the discharge area onto the beams covered with removable sheets. Moving

down to the receiving area under the action of their own gravity, they reach the base of the beams and pour out into the dumping container into the lowest undocked cell. As soon as it is filled, for example, the next sheet is pulled off with a bulldozer, thus another cell is exposed, where the rock is collapsing and so has given, it is upwards to the surface of the blade.

as a result, the slope acquires the shape. Upon completion, the entire structure is dismantled and installed elsewhere along the front of the groundwork.

To prevent possible gaps in moving rocks on metal sheets, it is allowed as an additional force. The use of rifle monitors, hydro-impulse guns and bulldozers. In the latter case, the metal sheets are replaced with more durable material, such as concrete slabs.

The use of hydromonitors and hydropulse guns is effective if the rock is moved but the surface is arranged in the form of a gutter.

For a more intensive movement of rocks on metal sheets, the sliding surface is attached to a parabolic profile, and on-site vehicles are elevated from overburden or concrete.

1. METHOD FOR FILLING BREEDS FROM SLOPES, including unloading the rocks at the unloading site of the upper slope element and moving them along the slope to the base of the slope to the receiving platform under the action of gravity from top to bottom, characterized in that, in order to expand the area of use of dumping when flattening slopes of dumps rock and soft rocks by providing the ability to control the flattening angle and safe technology of work, before starting unloading the rocks on the slope of the dump form a container for unloaded rocks Then, laying between the unloading and receiving platforms at an angle of flattening of the bearing beams with detachable elements forming a ramp installed on them, and as the rocks move along the ramp and the reservoir is gradually filled with rocks, the removable ramp elements are removed alternately from the bottom up. 2. The method of pop. 1, characterized in that the upper part of the supporting beams is made parabolic concave. 3. The method of pop. 1, characterized in that the unloading of the rocks is carried out from the elevation, which is arranged on the unloading platform at the top element of the ramp. SU _а „1229341
