AI Technical Summary

Problems solved by technology

As the mining depth increases, longer and longer winding roads are formed. At this time, the upward driving speed is about 10km / h, and the downward driving speed is about 35km / h. This requires the driver to be highly focused, and there will always be risk of major accident

Embodiment Construction

[0036] Fig. 1 has shown the inclined hoist 2 that is arranged in mining funnel 1 li, can have multiple hoists of the same form like this if necessary. The hoist is formed on a concrete foundation 3 and extends from the surface 4 to the bottom 5 of the funnel, which in the embodiment is at a depth of about 100 n from the surface 4 . The inclined conveyor or inclined hoist 2 with an inclination angle α of about 50° has a mobile platform 6 and a counterweight 7, which move in opposite directions through steel wire ropes 8, . . . 6, the other side is fixed on the counterweight 7. The steel cables 8, . Turn and be sent back to the steel rope drum 11 in reverse motion. The mobile platform 6 has supported a load truck 16 on a position to ensure safety. As shown in Figure 1, this vehicle has been loaded with mining materials from the bottom of the funnel 5 and transported upwards, so the counterweight 7 is located at the lower position towards the bottom of the funnel 5 . Mobile p...

Abstract

An inclined elevator for excavating an open cut mine in scopes has a traveling platform and counterweight coupled by cables whose upper and lower passes extend over upper and lower cable pulleys to the drum of a conveyor or drive machine. The cables can pass around a rerouting pulley which can be shifted on the foundation for the inclined elevator to compensate for increased depth of the excavation. The traveling platform which carries the car or truck for the mined material can have pins engaging in a bottom which is removable from the platform and can be locked in upper and lower positions relative to the foundation by pawls engaging in notches or recesses of the bottom.

Description

technical field [0001] The present invention relates to a kind of hoisting equipment for open-pit mines, especially for removing the ore seam and the tail gangue produced when mining is pushed horizontally on the stepped mining belt. Wide mining funnel. Background technique [0002] When carrying out mining operations on the ground, the surface layer above the ore seam must be stripped off earlier, and then the ore seam and the tailings must be removed. For this reason, minerals and strippings are mined on the so-called step section, that is, the stepped mining belt. Considering factors such as the strength of rock and soil, machinery equipment, and production economy, the height of the stair sections is about 15m on average. At the same time, in order to discharge gangue, an inclined plane is opened between the stair sections as a transportation channel. The deeper the ore seam is mined, the greater the opening of the resulting mining funnel that widens upwards by about 40...
