An integrated method of underground gangue transportation, crushing and filling in mines

Abstract

The invention discloses a mine underground gangue transportation, crushing and filling method, mainly comprising: adjusting expansion rack fastening nuts and rear moving drum bearing block nuts according to field conditions to allow a rubber belt to move back and forth; opening a speed control switch to start a motor; placing large gangue to be crushed onto a start belt, allowing to fall into a secondary crusher, and allowing the gangue crushed by the secondary crusher to enter a feeder; allowing the gangue to fall onto the rubber belt at a set speed and be transported to a filling region; after conveying the gangue to specified position of the filling region, opening a hydraulic push post to push a tamping plate to forwardly tamp the gangue pile; moving back and forth the front and rear moving drums and driving, through a track unit, a base and a steel frame to move as a whole in alternate manner, so that overall filling of the filling region is finished. The method herein has the advantages that, for instance, operation is easy, and steps are reasonable; the problem that the belts are complex to detach is solved; moving frequency of equipment is decreased; filling cost is reduced; working efficiency is improved.

Description

technical field [0001] The invention relates to an integrated method of gangue transportation-crushing-filling in mines. It is a self-designed method of using a self-designed multi-functional and fast underground gangue crushing and roadway filling mechanized device placed in the filling area for actual operation. It is specifically designed for mining transportation. How to use filling equipment. Background technique [0002] In coal mining, with the output of coal, a large amount of gangue will be produced. It is difficult to transport gangue underground, and the cost of raising the shaft is relatively high. In addition, after the gangue is raised into the shaft, it will form a gangue hill that occupies a large area and is seriously polluted. The gain outweighs the gain. The gangue is used in the way that the gangue is directly crushed and filled without going up the well. However, with the continuous filling of gangue, the gangue conveying device needs to be continuously...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the defects of multiple belts and frequent movement of filling and loading in the existing mine underground filling equipment, and provides an integrated method of underground gangue transportation, crushing and filling, aiming at solving the problem of belt conveyor lengthening, shortening and For the problem of frequent movement of equipment, a multi-purpose model is adopted to more effectively solve the complicated steps in the process of gangue from transportation to filling, and achieve the purpose of refinement and diversification of underground filling equipment in mines
