A water inrush emergency water blocking method and water blocking device

Abstract

The invention relates to a water bursting emergency water blocking method and a water blocking device, and discloses a water blocking method and device, wherein the water blocking device is fixedly mounted by cooperating with anchor rods, and blocking is conducted through airbag inflating expansion. The water bursting emergency water blocking method is characterized by comprising the steps: the water blocking device is expanded, and the four corners of the water blocking device are connected and fastened with the support anchor rods; an outer connecting sleeve on the water blocking device communicates with an external pump body; a layer of anchor mesh is laid on the surface where the water blocking device is fixed, and fixed through the anchor rods, and the water blocking device is fixed;the water blocking device is filled by starting the external pump body; the water blocking device is gradually expanded, meanwhile, the anchor mesh is fastened, the expanded water blocking device is fixed, and thus the water blocking device can be tightly attached to the rock wall initially; and the water blocking device is completely filled and completely attached to the rock wall, emergency water blocking is completed, and subsequent reinforcement work is conducted. The water blocking method is simple, mounting and fixing are conducted based on the original support anchor rods, and the situation that fixing lacks in supporting is avoided.

Description

technical field [0001] The invention relates to a water inrush emergency water blocking method and a water blocking device thereof, and relates to a method and a water blocking device for rapidly blocking water inrush in a mine, belonging to the field of coal mine equipment. In particular, it relates to a water blocking method and a water blocking device which are fixedly installed in cooperation with anchor rods and blocked by inflation and expansion of an air bag.

[0002] At present, in the process of underground mining, the occurrence of water inrush accidents will lead to underground safety accidents, especially in water-rich areas, mine water often flows or pours into roadways or working faces. Mine water inrush refers to the sudden occurrence of water in the aquifer. Abnormal influx into the mining face, resulting in flooding of local mines or the entire mine. Mine water inrush is affected by factors such as geology and mining conditions, and is the result of a combination of factors. In the prevention of underground water inrush, It is carried out by leaving waterproof coal pillars, drainage and pressure reduction, aquifer reconstruction, aquifer reinforcement, construction of waterproof gates, grouting and water blocking, etc., but all focus on the prevention of water inrush, and no emergency response to sudden water inrush Especially in the complicated hydrogeological conditions of the mining area, the coal seam mining operation is threatened by the water body, which affects the safety of mining, and the above-mentioned prevention process, the construction process is complicated, the cycle is relatively long, and the emergency water plugging cannot be carried out quickly

[0003] Publication number CN108005719A discloses a water inrush emergency water blocking wall device and its application method, including a water inrush emergency water blocking wall device and an application method, and the water inrush emergency water blocking wall device includes an air-filled wall and a water-filled wall. A water-filled wall is provided on one side of the working surface of the inflatable wall, and a gas generating device is provided inside the inflatable wall, and a microprocessor is provided on the outer wall of the inflatable wall away from the water-filled wall, and the gas generating device and The inflatable wall is connected, and the upper part of the inflatable wall is horizontally provided with a water injection pipe, one end of the water injection pipe extends to the water inflatable wall, and the other end of the water injection pipe extends out of the inflatable wall and is connected to a high-pressure water pump. The lower part of the inflatable wall is horizontally provided with a drainpipe, one end of the drainpipe extends to the water-filled wall, and the other end of the drainpipe protrudes from the outside of the inflatable wall and is provided with an opening and closing valve. The inflatable wall and the water-filled wall The inner level of the inner level is evenly provided with high-strength fiber filaments, the area of ​​the water-filled wall away from the inflatable wall is the excavation area of ​​the working face, the excavation area of ​​the working face is equipped with a water inrush sensor, and the water-filled wall is far away from the outside of the inflatable wall The wall is uniformly provided with water inrush injection holes, and a one-way valve is provided inside the water inrush injection holes. In this invention, the inflatable wall is laid and expanded through the gas generator, so that it can be attached to the rock wall of the roadway to form a water blocking , but its water blocking effect on the water inrush point is poor, and it is only fixed by anchor rods. During the inflation process, the support is poor, and it cannot form a complete supporting water blocking

[0004] Publication number CN208379595U discloses a pressure relief and water blocking device for foundation pit inrush water, including a control valve, a drain pipe, water blocking filler and a packing mesh sleeve. The control valve is installed at one end of the drain pipe, and the packing mesh sleeve is sleeve-shaped. Structure, there are mesh holes on the side wall of the filler mesh sleeve, the filler mesh sleeve is set on the other end of the drain pipe, a filler cavity is formed between the filler mesh sleeve and the drain pipe, and a water blocking filler is placed in the filler cavity. When the water blocking device has a filler After one end of the net sleeve is placed in the water gushing hole of the foundation pit, concrete slurry is injected into the filler net sleeve, and the concrete slurry fills the gap between the water blocking fillers and flows out from the mesh hole on the side wall of the filler net sleeve to fill in the In the gap between the packing mesh sleeve and the water gushing hole, the device mainly blocks the water gushing hole by blocking the water gushing hole. The blocking range is limited, and the fixing method is fixed by barbs. The stability of the method is poor, and the plugging effect around the water gushing hole is poor
