Open-air slope coal mining and transporting device and working face rapid transferring method thereof

Abstract

The invention aims to provide an open-air slope coal mining and transporting device and a working face rapid transferring method thereof. The open-air slope coal mining and transporting device comprises a sliding steering system, a travelling slewing system and a material conveying system. The sliding steering system comprises sliding boots mounted on the front portion of a main beam of a truss, steering device sleeves and sliding boot guiding cylinders, wherein the steering device sleeves and the sliding boot guiding cylinders are mounted on the main beam of the truss; telescopic rods are mounted inside the steering device sleeves; and idler wheels are mounted at the lower ends of the telescopic rods. The travelling slewing system comprises a crawler travelling mechanism, a slewing bearing and a slewing disc, and a connecting frame is mounted on the slewing disc and fixedly connected with a cross beam of the truss. The material conveying system comprises the truss and a belt conveyormounted on the truss. The open-air slope coal mining and transporting device is open-pit coal mine large-scale transporting equipment and is used for efficiently transporting coal cut by a continuousminer to an open-air square, the number of unit frames of a conveying device can be increased according to the mining depths of chambers, after deep mining of the current chamber is completed, the open-air slope coal mining and transporting device can be quickly transferred to the adjacent chamber, thus the working efficiency is high, and flexibility is achieved.

Description

technical field [0001] The invention belongs to the field of mining machinery, and in particular relates to an open-pit side coal mining transportation device and a method for quickly transferring a working face. Background technique [0002] In domestic open-pit coal mining, due to the irregular shape of the ore field and the small area of ​​the stope, a large amount of coal is pressed on the sides, and the secondary recovery is difficult, resulting in waste of coal. At present, a number of open-pit coal mining enterprises in Inner Mongolia are trying to use continuous coal miners to carry out side-side coal mining operations with reloading conveyor belt conveyors to recover most of the side-side pressed coal, which has better solved the problem of waste of resources. However, when the continuous coal mining machine is used in conjunction with the reloading conveyor belt conveyor, there is a problem of intermittent transportation, which causes the coal cut by the continuous...

AI Technical Summary

Problems solved by technology

However, when the continuous coal mining machine is used in conjunction with the reloading conveyor belt conveyor, there is a problem of intermittent transportation, which causes the coal cut by the continuous coal mining machine to be unable to be transported to the open square in a timely manner; after the deep mining of the current chamber is completed, it is necessary to move When reversing, it takes a lot of manpower and material resources to transfer the transport belt conveyor to the next chamber working face, resulting in a serious imbalance between the mining time and the transfer time, which seriously affects the improvement of production efficiency
