Problems solved by technology

The conveying angle of the belt conveyor used in this invention is generally not greater than 18°, which is far lower than the comprehensive slope angle of the side. The belt conveyor cannot transport and lift materials along the side, and can only enter and exit the ditch or enter and exit the side with a gentle excavation angle. Tunnels, entry and exit trenches or relatively fixed positions of entry and exit tunnels seriously restrict the advancement of internal drainage in open-pit mines

Embodiment 1

[0078] Such as figure 1 As shown, this embodiment is used in the working condition that the material loaded into the truck 2 by the mining equipment 1 is a small piece of material. The semi-continuous mining process system of the single mobile complete equipment is composed of the mining equipment 1, the truck The feeder 3 and the side lift conveyor 7 are composed. At this time, the mining equipment 1 includes an electric shovel, a hydraulic shovel, a loader, a bucket wheel excavator, a scraper and / or a surface mining machine and the like.

[0079] A mining method employing the above system comprises the following steps:

[0080] Step 1) Mining equipment 1 loads small pieces of material into truck 2;

[0081] Step 2) The truck 2 transports the small pieces of material to the mobile feeder 3 and unloads it into the receiving part of the mobile feeder 3 (or unloads it near the receiving part of the mobile feeder 3 and then uses a loader or Other auxiliary equipment is charge...

Embodiment 2

[0087] Such as figure 2 As shown, this embodiment is used in the working condition that the material loaded into the truck 2 by the mining equipment 1 is a small piece of material. The semi-continuous mining process system of the single mobile complete set of equipment is based on the first embodiment. A mobile reloading machine 6 is set between the machine 3 and the sidewall hoisting conveyor 7.

[0088] Using the mining method of the above system, on the basis of Embodiment 1, change step 3) to, the mobile feeder 3 transfers the small material to the receiving part of the mobile transfer machine 6, and the mobile transfer machine 6 will The small pieces of material are transferred to the side-side lifting conveyor 7, and the side-side lifting conveyor 7 lifts the small pieces of material to the pit and then enters the downstream process link.

[0089] The relocation process includes the following steps (excavation equipment 1 is always pushed along with the working face; t...

Embodiment 3

[0093] Such as image 3 As shown, this embodiment is used in the working condition that the material loaded into the truck 2 by the mining equipment 1 is a medium-block material. Above, a mobile secondary crusher 5 is set between the mobile feeder 3 and the side lift conveyor 7 . At this time, the mining equipment 1 includes an electric shovel, a hydraulic shovel, a loader, a bucket wheel excavator, and / or a scraper, and the like.

[0094] A mining method employing the above system comprises the following steps:

[0095] Step 1) Mining equipment 1 loads medium-block materials into truck 2;

[0096]Step 2) The truck 2 transports the medium-block material to the mobile feeder 3 and unloads it into the receiving part of the mobile feeder 3 (or unloads it near the receiving part of the mobile feeder 3 and then uses a loader or Other auxiliary equipment is charged to the receiving part of the mobile feeder 3);

[0097] Step 3) The mobile feeder 3 transfers the medium-sized mate...

Abstract

A semi-continuous mining system of single body movable type complete equipment comprises excavation equipment, a truck, a movable type feeder and a sidewall hoisting conveyer which are connected successively. According to the technical scheme, the excavation equipment is positioned on a working face, the movable type feeder, a movable primary crusher, a movable secondary crusher and a movable transfer machine are positioned in a pit, a head of the sidewall hoisting conveyer is arranged on the pit, the tail of the sidewall hoisting conveyer is arranged in the pit, and a middle section is mounted along a step of a sidewall; the truck goes there and back between the excavation equipment and the movable feeder; the sidewall hoisting conveyer has a self-moving structure, an aided moving structure and / or a fixed support structure which can be assembled and disassembled rapidly; and the sidewall hoisting conveyer can hoist and convey materials at a large angle (greater than 25 degrees), and can hoist and convey the materials along the side wall of an optional comprehensive slope corner. The semi-continuous mining system of single body movable type complete equipment has the advantages of simple structure, independent function, flexibility in operation, convenience in movement and the like, can be matched with the working face, and goes forward quickly on the inner row, the cost is low, and the utilization rate of the sidewall comprehensive slope corner of an open-pit mine is greatly increased.

Description

technical field [0001] The invention relates to the field of open-pit mining, in particular to a semi-continuous mining process system of single mobile complete equipment. Background technique [0002] Open-pit mines widely adopt single-bucket excavator-truck intermittent mining process, single-bucket excavator-truck-semi-mobile crushing station-belt conveyor semi-continuous mining process and single-bucket excavator-self-moving crusher-belt conveyor machine semi-continuous mining process. In the single-bucket excavator-truck intermittent mining process, the trucks are transported through the side walls, and each step of the side walls needs to be equipped with a vehicle passage, resulting in small side slope angles, large stripping volumes, large blasting ranges, and large truck transportation volumes. The environmental pollution is serious, and the trucks have a long return transport distance and high energy consumption, which further aggravates the environmental pollutio...
