Water burst emergency water plugging wall device and application method thereof

Abstract

The invention discloses a water burst emergency water plugging wall device and an application method thereof, and includes a water burst emergency water plugging wall device and an application method.The application method comprises: at the moment of water burst, the device responding immediately, a gas generator in an inflation wall firstly reacts rapidly, large amount of generated gas rapidly strutting the inflation wall, then a high-pressure water-injection pump rapidly injecting water to the inflation wall, and a water burst one-way valve on a water burst wall working face side making bursting water inject into the inflation wall, to make the inflation wall expand rapidly; when the inflation wall is horizontally abutted against with a roadway, high-strength filaments in the inflationwall being completely stretched to generate a powerful constraining force, to make the inflation wall only expand along a section of the roadway subsequently, continuing to inject water, a water plugging wall continuously extruding with the roadway, to generate high friction force, so as to achieve an emergency water plugging wall effect. When a working face is unsealed, through controlling a valve, hydrops plugged by the working face can be discharged according to water discharge capacity. The device is good in emergency water plugging effect, and is simple in process and high in efficiency.

Description

Technical field [0001] The invention relates to the technical field of coal mine safety, and the specific field is a water inrush emergency water blocking wall device and an application method thereof. Background technique [0002] In the production process of coal mines, mine water is often seen flowing into or flowing into roadways or working faces. This is mine water. The sources of mine water include surface water, aquifer water, old kiln water and fault water. Mine water inrush refers to the sudden and abnormal influx of water from the aquifer into the mining face, which increases the amount of water inflow from the mine and causes the flooding of local mines or the entire mine. The occurrence of mine water inrush is affected by various factors such as geology, hydrogeology, mining conditions, etc., and is the result of multiple factors. Preventing flooding is the most critical and urgent problem faced by production in rich water mining areas. There are currently five trea...
