The method of ore transportation realized by truck lifting system of side side adit and shaft in open-pit mine

Abstract

The method for realizing ore transportation by the side adit and shaft truck lifting system of an open-pit mine belongs to the technical field of open-pit mineral material transportation. It overcomes the need to set up a crushing station in the pit by using a belt conveyor for transportation in the prior art, and build a belt conveyor road, which occupies a large area in the pit. The problem of space and the greatly reduced efficiency of mineral transportation methods dominated by heavy-duty trucks is characterized by the establishment of an adit at the bottom of the side of the open-pit mine, and the laying of two-lane trolley tracks on the truck transportation channel established on the ground of the adit , on the track of the trolley, there is a trolley on the right and a trolley on the left, and a vertical shaft is established at a safe place on the ground outside the open-pit mine boundary. And the programmable control system, the beneficial effect is that there is no crushing station in the pit, and there is no need to build belt conveyors and arrange belt conveyors, which reduces the engineering cost, retains the mobility of heavy-duty trucks, improves transportation efficiency, and reduces operating costs.

Description

The method of realizing ore transportation by the truck lifting system of the side gangway and the vertical shaft of the open-pit mine technical field The invention belongs to the technical field of open-pit mineral material conveying, and particularly relates to deep ore and stripping for open-pit mine excavation field. The method of realizing ore transportation by the side gangway and the vertical shaft truck lifting system for the open-pit mine conveying. Background technique [0002] With the continuous growth of the demand for natural resources, open-pit mining continues to develop towards large-scale development. It is a technical problem that must be solved to transport the deep ores and strips that have been mined in the mining field to the ground. current technology Among them, the traditional transportation methods are road transportation or combined transportation. The most commonly used equipment for road transportation is self-unloading heavy-duty trucks. ...

Problems solved by technology

[0003] One is to use the belt conveyor for transportation, which requires the ore to be small in size. The ore after blasting needs to be further crushed before it can be transported by the belt conveyor. Therefore, a crushing station needs to be set up in the pit to make the material meet the conveyor requirements of the belt conveyor, thus reducing the system cost. Mobility, the crushing station also occupies a large space in the pit, and the construction cost of the crushing station is relatively high. When a mobile crushing station is used, the moving work of the crushing station is also very complicated;

[0004] Second, it is necessary to rely on a stable side to build the belt conveyor road to meet the needs of the belt conveyor layout;

[0005] The third is to transport through the belt conveyor. In addition to the power consumption of the conveyed materials, the power consumption of the belt conveyor system itself is also relatively large. Moreover, the ordinary belt conveyor is limited by the dynamic accumulation angle of the material and the friction coefficient between the material and the belt. , the lifting inclination angle can only be around 18°. For the belt conveyors that generally convey bulk materials, the maximum conveying lifting angle is required to be no more than 16°, resulting in a large area for the layout of the belt conveyor, a large amount of engineering, and a long conveying route.

If the inclination angle of the belt conveyor is increased, the force of the material falling downward during the transportation process will increase, and the phenomenon of material scattering will be serious. When the ore with high hardness is transported, the belt wear will be large and the aging will increase, which will increase the maintenance of the equipment. volume and maintenance costs;

[0006] The fourth is to directly use heavy-duty trucks for transportation. As the climbing height increases, the return road becomes longer and longer, which greatly reduces the efficiency of heavy-duty truck-based mineral transportation methods.

This utility model provides that the lifting frame is driven by a linear motor to move up and down, so as to realize the parking and lifting of general vehicles such as cars. The driving power of the lift is small, and the deep ore and stripped material transportation in the open-pit mine excavation site, if heavy-duty trucks are used for transportation, the heavy-duty trucks used are generally 90T mining dump heavy-duty trucks, with a full load of 90 tons and an empty load. The mass is 28 tons, and the overall dimensions are 8710mm long, 3504mm wide, and 4250mm high. and translation components are unable to meet the lifting needs of such heavy-duty trucks
