Problems solved by technology

[0004] For some large water mines, in order to prevent a large potential outburst (inrush) of water, two or three drainage pipelines have to be arranged, plus water supply pipes and air pressure pipes, so that four or three trips are arranged on the side of the roadway Five trips of pipelines, these pipelines are not specially hung on the side by anchor bolts, or are pulled and hoisted by roof bolts or anchor cables, which will add a large additional load to the roof or side of the roadway, which will easily cause roadway enclosure. rock failure or instability, which is one
Second, mine water inrush is a potential threat, which may or may not come out, regardless of whether the water will come out or not, it is necessary to pre-install drainage pipelines sufficient to relieve the potential water inrush, which will cause a particularly large underground roadway pipeline project. , the cost of underground installation is increased, resulting in huge waste
[0005] It can be seen that if a water inrush occurs, the mine drainage system may not be able to drain in time. If a large number of drainage pipes are laid, it will cause additional damage to the roadway and increase the cost

Embodiment 1

[0021] Such as figure 1 As shown, an emergency drainage and rescue system for underground water disasters includes a water supply pipe 3 installed underground, a drainage pipe and a pressure air pipe 1; Pipe 2.3; a pressure air pipe three-way valve 1.2 is installed on the side of the pressure air pipe 1 facing the direction of the roadway or the working face, and a water supply pipe three-way valve 3.2 is installed on the side of the water supply pipe 3 facing the direction of the roadway or the working face; A drainage pump 1.4 for draining water when a water inrush occurs is installed on the pressure air pipe 1; a water supply pipe for controlling water supply from the water supply pipe to the working face and roadway is installed between the water supply pipe 3 and the three-way valve 3.2 of the water supply pipe. The upstream control valve 3.1 of the pipe, the water supply pipe and the upstream control valve 3.1 of the water supply pipe are connected through a variable dia...

Embodiment 2

[0026] Such as figure 2 The underground water disaster emergency drainage rescue system shown is an emergency drainage rescue system for underground water disasters, which includes a water supply pipe 3, a drainage pipe and a pressure air pipe 1 installed in the underground; the drainage pipe includes the main drainage pipe 2 and the main drainage pipe 2. The branch drain pipe 2.3 connected to the pipe 2; the pressure air pipe three-way valve 1.2 is installed on the side of the air pressure pipe 1 facing the direction of the roadway or the working surface, and the water supply pipe three-way valve is installed on the side of the water supply pipe 3 facing the direction of the roadway or the working surface 3.2; the water supply pipe 3 and the pressure air pipe 1 are respectively installed with a drainage pump 1.4 for draining water when water inrush occurs; a water supply pipe is installed between the water supply pipe 3 and the water supply pipe three-way valve 3.2 to control...

Abstract

The invention discloses an underground flood damage emergency water draining rescue system and method and belongs to the field of mine water seepage emergency water draining. The specific scheme is that the existing water supply pipe, the existing pressure ventilation pipe and the existing drain pipe are utilized, and upstream valves and three-way devices with valves are installed on the water supply pipe and the pressure ventilation pipe. The water drain valve end is closed under the normal condition to enable the original water supply and pressure ventilation functions to be achieved. Under the emergency condition, the upstream valves in the water supply and pressure ventilation directions are closed, the three-way devices with the valves are opened, so that the water supply pipe and the pressure ventilation pipe can serve as temporary drain pipes, two more drain pipes are obtained, and the draining amount of 300m<3> / h can be increased according to the capacity of 150m<3> / h of each drain pipe. The system and method can basically prevent or reduce major water burst accidents and win precious time for handling of the water burst accidents.

Description

technical field [0001] The invention relates to a mine permeable emergency rescue system, in particular to an underground water disaster emergency drainage rescue system and a rescue method thereof. Background technique [0002] When a flood disaster occurs, time is life and time is money. According to past experience, after flooding accidents, the drainage system is not perfect and the emergency response is not timely. Some enterprises pay more attention to production than safety, and have no spare materials and equipment for emergency rescue and disaster relief. The rescue efficiency is low and the rescue effect is poor; After the accident, drainage equipment will always be dispatched from various parties, and such pictures of rushing to transport emergency equipment have often appeared in news reports. Some enterprises formulate emergency plans for water disasters, but in fact they fail to implement them properly. When the water inrush disaster comes, it will either cau...
