Abstract
The utility model discloses an exploit drainage device for a coal mine, which comprises a drainage pipe, wherein the drainage pipe is inserted in a drainage drill hole, the outer side end of the drainage pipe is connected with a water duct by a flange, wherein the water duct is provided with a control valve. The exploit drainage device for the coal mine is simple in structure, can conveniently and quickly conduct drainage work to a mining area of the coal mine, has no need of rebuilding a settling tank and is convenient to use.
Description
Technical field
The utility model relates to a kind of colliery with visiting jettison gear.
Background technology
In Coal Production,Original spy technology that discharges water adopts the rig punching, and direct and goaf conducting discharges water, and need sedimentation basin be set in advance, and labor intensive reduces work efficiency.Because boring itself is uncontrollable to current size and toxic and harmful outburst amount, cause the work plane can't ordinary production, visiting needs stopping production between blowoff period, finishing of mine production task is affected.
Summary of the invention
The purpose of this utility model is to provide a kind of colliery with visiting jettison gear, and it is simple in structure, and the gas-liquid flow that can visit in the boring that discharges water coal mine gob is effectively controlled, and guarantees the work plane ordinary production.
The purpose of this utility model is achieved in that a kind of colliery with visiting jettison gear, and this device comprises a drainage tube, and drainage tube is inserted in the drainage boring, and the outboard end of drainage tube is connecting a water-supply-pipe that has by-pass valve control by flange.
The utility model adopts prefabricated sleeve pipe to visit jettison gear, by pre-buried drainage tube in boring, has reached current controllable operating in holing.After the boring conducting, withdraw from drilling rod, to rig down, mounted valve connects water-supply-pipe in the transportation lane with bend pipe, and Open valve is gushed out to current size in holing and goaf toxic and harmful and to be controlled.Adopt this device, reduced artificial input, need not to be provided with sedimentation basin, improved work efficiency.In to goaf ponding processing procedure, work plane still can ordinary production, need not to stop.Because the application of this device, the possibility of gushing water takes place when having solved the leading pre-explosion of stope, realized safe back production, for the colliery later stage is visited the work of discharging water and establishes solid technical foundation.In work progress, can reduce artificial input, save the lot of materials expense, do not influence production task, can improve work efficiency, for mine increases tangible benefit.This apparatus structure is simple, and the gas-liquid flow that can visit in the boring that discharges water coal mine gob is effectively controlled, and can carry out draining to coal mine gob quickly and easily, need not to build sedimentation basin again, guarantees the work plane ordinary production, and is easy to use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a main TV structure schematic diagram of the present utility model.
The specific embodiment
A kind of colliery is with visiting jettison gear, and as shown in Figure 1, this device comprises a drainage tube 4, and annular retaining pawl is being set on the axial periphery wall of drainage tube uniformly at intervals, withdraws from boring in order to prevent drainage tube 4 under powerful hydraulic action.Drainage tube 4 is inserted in the drainage boring 5, and the outboard end of drainage tube 4 is connecting a water-supply-pipe 1 that has by-pass valve control 2 by flange 3.The utility model is simple in structure, can carry out draining to coal mine gob quickly and easily, need not to build sedimentation basin again, and is easy to use.
Claims (2)
1. a colliery is with visiting jettison gear, and it is characterized in that: this device comprises a drainage tube, and drainage tube is inserted in the drainage boring, and the outboard end of drainage tube is connecting a water-supply-pipe that has by-pass valve control by flange.
