Self-moving-type disaster isolation sluice wall

Abstract

The invention relates to the technical field of coal industries, in particular to a self-moving-type disaster isolation sluice wall. The self-moving-type disaster isolation sluice wall comprises a sluice wall body and a control mechanism; the sluice wall body is movably arranged in a roadway, can continuously move forwards along with advancing of a driving working face, and is used for isolating the roadway into a hectometer danger-relieving area and a normal working area; the sluice wall body is provided with an upper sluice gate and a lower sluice gate, and the control mechanism is used forcontrolling opening and closing of the upper sluice gate and the lower sluice gate. By means of the self-moving-type disaster isolation sluice wall, the urgent demand of coal mining work for securitycan be effectively met, unmanning of the hectometer danger-relieving roadway, closing of disastrous accidents and mechanization of personnel evacuation are achieved, fiver disasters of water, fire, gas, coal dust and roofs during roadway drivage are reduced or removed, and injuries and death of coal mining personnel are reduced.

Description

technical field [0001] The invention relates to the technical field of the coal industry, in particular to a self-moving disaster isolation gate wall. Background technique [0002] At present, the five natural disasters in coal mines refer to: floods, fires, gas explosions, coal dust, and roof accidents. [0003] 1. Flood [0004] A large amount of flooding swallowed the tunnel in a short time, causing the death of all the staff. Usually the survivors cannot be rescued, the remains cannot be recovered, and the tunnels are also abandoned. Water inrush and permeation accidents may also occur in coal mining above confined water and in damaged areas of small coal kilns. Underground water inrush and small coal kiln water seepage accidents are far more than coal mining water seepage accidents under water bodies. [0005] 2. Fire [0006] Worst case scenario in coal mine accident. Unlike general fires, there are many combustibles (coal) around. If the exit of the tunnel is b...

AI Technical Summary

Problems solved by technology

[0005] 2. Fire

If the exit of the tunnel is blocked by heat and smoke, and a lack of oxygen occurs at the same time, it will usually cause serious casualties

[0007] 3. Gas explosion

[0009] 4. Coal dust

[0011] 5. Roof accident

If our support is not timely or the support strength is not enough, it is easy to cause the roof rock layer of the working face to break and fall, causing casualties and property and equipment losses. This is what we call a roof fall accident.
