Spiral coal-loader type underground coal storage device

Abstract

The invention spiral coal-feeding type underground coal-storing device belongs to mining and mechanism, relates to a coal pit underground tunnel engineering and a device which stores underground coal and buffers the coal transferring system. Only vertical coal bins is adopted so far in the nation, which structurally requires altitude difference, toughening up the tunnel arrangement of some sub-horizontal coal bed by increasing the rock tunnel works, while discomforting the split charging and transferring of coal and dirt. The invention provides with a coal-storing device which is adaptive to underground mining and buffering the coal transferring system by being installed in the horizontal tunnels in the coal mine, not only solving the problem that the horizontal coal bed underground tunnel arrangement is of large tasks, but also acquiring advantages suck as simple, reliable, easy transportation, very small increase of cost while increasing the coal bin capacity which meets the needs of high adaptability and high economical efficiency.

Description

technical field [0001] The "screw coal loader type underground coal storage device" of the present invention belongs to the field of mining and machinery, and relates to a coal mine underground roadway engineering technology, a mechanical device for storing underground coal in a coal mine and buffering an underground coal transportation system. Background technique [0002] In mining engineering production, in order to buffer the impact of failures during coal transportation, improve the reliability of transportation, effectively ensure the continuous production of mining face, and improve the utilization rate and work efficiency of transportation equipment, it is necessary to install underground Coal bunkers. At present, vertical coal bunkers are used in China. Vertical coal bunkers require height differences in structure, which brings difficulties in increasing the amount of engineering for the roadway layout of near-horizontal coal seams, and is not convenient for the sepa...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art, to provide a coal storage device suitable for buffering the transportation system in underground mining projects, which is installed in the horizontal roadway of the coal mine, not only to solve the problem of rock roadway projects in the vertical storage of near-horizontal coal seams The problem of large quantity, and the equipment is simple, reliable, and easy to carry. When the capacity of the coal bunker increases, the cost increases very little, so as to meet the high adaptability and economical requirements of the large-capacity coal bunker.
