A shelter for deep well and underground driving

Abstract

The invention provides a shelter for underground mining in deep wells, which relates to the technical field of underground mining. In the present invention, when the device is opened, the motor drives the turntable to rotate, the turntable drives the top wheel to rotate, and when the top wheel is in contact with the sliding plate, the sliding plate drives the moving rod to move, the moving rod slides inside the insert block, and the insert The block will limit the moving rod, the limiting plate will prevent the moving rod from leaving the insert block, the sliding plate will pull the return spring, when the sliding plate moves, the ejector rod will move, the ejector rod will drive the roof to move, and the dust screen will cover the dust. , to prevent dust from entering the interior of the housing frame from the top of the frame, when the top wheel is not in contact with the sliding plate, the reset spring drives the sliding plate to reset, the sliding plate drives the moving rod to reset, and the sliding plate drives the top rod to reset, so that the top The rod is reset to make the roof vibrate, preventing the top of the roof from accumulating and causing the roof to collapse.

Description

technical field [0001] The invention relates to the technical field of underground mining, in particular to a shelter for deep well underground mining. Background technique [0002] In coal mine production, underground mining is the most important way, so it is of great practical significance to study underground mining technology. The application of underground mining technology must be adapted to the situation of coal mine geology and coal seam distribution. And make a good mining plan in advance, determine the application and support of the equipment. In open-pit mining, direct mining is generally used, but in underground mining, due to the constraints of environment, equipment and other conditions, top-to-bottom mining is usually used. With the continuous development of mining technology, directional mining methods have gradually been widely used. [0003] When mining underground, for safety reasons, shelters will be installed underground. Most of the existing shelter...

AI Technical Summary

Problems solved by technology

[0003] When mining underground, for the sake of safety, shelters will be installed underground. Most of the existing shelters use light steel as a bracket for installation. However, when this kind of shelter is in use, if the collapsed area is directly above the shelter, such as coal mines, there will be more soil falling, and coal will easily accumulate on the top of the shelter. Once the weight is too large, it will easily cause dodging collapse of the roof
