Abstract

The utility model provides a device for draining the water accumulated in a gas drill hole under a coal mine well by means of pumping. The device comprises a pressure ventilation pipe, an extraction pipe, a stop valve, a suction branch, a drainage pipe, a drainage device and the like. The suction branch is connected with the pressure ventilation pipe and the extraction pipe by a tee joint and two valves. The drainage pipe is arranged at one end of a drilling orifice, is internally sheathed in the suction branch, is punched and penetrated from the wall of the suction branch at the exterior of the orifice, and is inserted into the extraction pipe and the drainage device. Due to the joint function of the positive pressure of the pressure ventilation pipe and the negative pressure in the extraction pipe, the water accumulated in the drill hole can be quickly drained.

Description

Pump drainage coal mine underground gas borehole ponding device
Affiliated technical field
The utility model relate to a kind of can pump drainage coal mine underground gas borehole ponding device, be particularly useful for down to boring.
Background technology
According to " the outstanding regulation of control coal and gas " requirement, a large amount of coal (rock) mash gas pumping drilling needs under the coal mine to construct.Along with the prolongation of time, the water in coal (rock) the slabbing crack is assembled in boring, forms ponding gradually to boring the inside down, and under the big situation of coal (rock) layer water content, even the short time internal drilling just can be filled with ponding.Boring in ponding influence the gas pumping effect to a great extent, some in addition can't extract gas out, cause very big waste.
Summary of the invention
In order to solve down the ponding problem in boring, the utility model provides a kind of pump drainage coal mine underground gas borehole ponding device, can get rid of the ponding in boring down easily, helps carrying out gas pumping.
The technical scheme that its technical problem that solves the utility model adopts is: this device is made up of pressure ventilation pipe, exhaust tube, stop valve, suction branch, gutter and tailrace etc.Suction branch is connected with pressure ventilation pipe, exhaust tube with two valves by a threeway.Gutter is positioned at a section of drilling orifice, in be enclosed within the suction branch, pass from suction branch tube wall punching in the outside, aperture, insert exhaust tube and tailrace.
The function of this device realizes as follows:
Under the situation of normal mash gas extraction, stop valve 3 is closed, and stop valve 4 is opened, and the gas in the boring enters exhaust tube through suction branch and gutter and taken away.When having ponding in the boring, close stop valve 4, open stop valve 3, compressed air enters boring through pressure ventilation pipe and suction branch and makes formation malleation in the boring, at this simultaneously, the negative pressure that exhaust tube produces makes and forms certain vacuum in the gutter, and both actings in conjunction make the water in the boring enter tailrace water is discharged through water inlet, the gutter of gutter.After treating that water has been arranged, close stop valve 3, open stop valve 4, can normal mash gas extraction.
The beneficial effects of the utility model are: this device is simple to operate, does not need electricity consumption, avoids the explosion-proof managerial trouble of underground coal mine electrical equipment.
Description of drawings
Accompanying drawing is a schematic diagram of the present utility model.Pressure ventilation pipe 1, exhaust tube 2, stop valve 3, stop valve 4, suction branch 5, gutter 6 and tailrace 7 among the figure.
The specific embodiment
Pressure ventilation pipe 1 is the steel pipe of φ 50-108mm; Exhaust tube 2 is the two anti-plastic pipe of φ 200-250mm; Suction branch 5 is the two anti-plastic pipe of φ 75mm, length 10m; Gutter 6 is the two anti-plastic pipe of φ 5mm, and length is less than brill Hole depth 0.5m, it is the plastic pipe of 0.3m that its end (being called water inlet) that is positioned at foot of hole is installed one section φ 50mm length, suitable uniform aperture around this section plastic pipe is so that water inlet and filtration foreign material prevent to stop up gutter; Tailrace 7 is made up of float and several groups of valves, is made by specialized factory.
