The specific embodiment
With reference to figure 1, the lower structural representation to the boring drainage system that Fig. 1 provides for the utility model embodiment.
As shown in Figure 1, what present embodiment provided is lower to the boring drainage system, comprises hole sealing tube 1, extraction pipeline 2, air line 3 and water trap 4.
The outlet air end of air line 3 is arranged in the hole sealing tube 1 and extends to the bottom of hole sealing tube 1, and the upper end of hole sealing tube 1 is communicated with extraction pipeline 2, and the water inlet of water trap 4 is communicated with extraction pipeline 2.
Under the colliery in the hole pumping and mining process, need to carry out sealing of hole to boring, hole sealing tube 1 is arranged on the sealing of hole section of boring, the lower end of hole sealing tube 1 extends to the depths of boring, the top and bottom of hole sealing tube 1 have opening, the negative pressure suction force that extraction pipeline 2 provides to hole sealing tube 1 is taken the gas in the boring away.
Particularly, air line 3 can comprise presses wind house steward 31 and a plurality of pressure wind to be in charge of 32, and a plurality of pressure wind are in charge of 32 and all are communicated with pressing wind house steward 31, and each pressure wind be in charge of 32 respectively deep to a hole sealing tube 1 the bottom and be communicated with this hole sealing tube 1.Extraction pipeline 2 can comprise extraction house steward 21 and a plurality of extraction air line 3, and a plurality of extractions are in charge of 22 and are communicated with extraction house steward 21, and each extraction is in charge of 22 and is communicated with a hole sealing tube 1.Air line 3 and extraction pipeline 2 adopt the blast main structure, can carry out extraction to a plurality of hole sealing tubes 1 simultaneously, can improve extraction efficient.
The below specifies lower principle and the course of work to the boring drainage system that above-described embodiment provides:
Open air line 3, blow out by will hole internal water accumulation and gas of air line 3 interior pressure wind, beat simultaneously extraction pressure pipe road 2, utilize extraction pipeline 2 negative pressure that ponding and gas in the hole sealing tube 1 are carried out extraction, then utilize the water trap 4 of installing on the extraction pipeline 2 that ponding is discharged, thereby reach expection draining purpose.
Concrete principle is explained as follows, and when being full of ponding in the boring, during pressure that the hydraulic pressure that ponding produces discharges greater than coal-bed gas, the gas in the boring can not discharge by boring, and extraction pipeline 2 mash gas extraction concentration and flow value are close to being zero.During ponding in extraction pipeline 2 is extracted part boring out, the interior water column of boring reduces, and hydraulic pressure also decreases, and coal-bed gas pressure is during greater than water column pressure, part gas can on float to the water surface, and obtain certain gas extraction concentration and flow.
But extraction system negative pressure is difficult to overcome the pressure that atmospheric pressure gives water column in the hole, so the negative pressure of extraction pipeline 2 can only be extracted part ponding in the boring out, seriously restricts gas pumping efficient.
What the use present embodiment provided is lower to the boring drainage system, and boring internal water accumulation and gas are by the mouth of pipe place of the pressure wind of air line 3 to hole sealing tube 1, and simultaneously, the negative pressure of extraction pipeline 2 is extracted the ponding and the gas that blow out in the hole sealing tube 1 out.
Occlusion pressure air pipe line 3 after the boring internal water accumulation is drained utilizes extraction pipeline 2 normal mash gas extractions; Again assemble and normally during mash gas extraction, can again open air line 3 when the boring internal water accumulation, pressure wind and the hole sealing tube 1 interior negative pressure of utilizing air line 3 to provide drain the water away jointly.
What present embodiment provided is lower to the boring drainage system, at the hole sealing tube 1 interior air line 3 that arranges, carry pressure wind by air line 3 to the bottom of hole sealing tube 1, press wind the ponding in the boring can be blowed to the mouth of pipe place of hole sealing tube 1, extraction pipeline 2 provides negative pressure to hole sealing tube 1, the pressure wind of air line 3 and the negative pressure acting in conjunction of hole sealing tube 1 in boring ponding and ponding discharged by water trap 4, thereby can improve the extraction efficient of the interior gas of boring.
On the basis of above-described embodiment, lower to boring drainage system also comprise controller 5 and a plurality of control valve 6, each control valve 6 is arranged on one and presses wind to be in charge of on 32, and controller 5 is electrically connected with described a plurality of control valves 6, with the unlatching of controlling each control valve 6 or close.Particularly, controller 5 can adopt programmable logic controller (PLC), and control valve 6 specifically can adopt electromagnetic valve.
Can realize pressing wind automatically to open or close by controller 5 and control valve 6, thereby the realization discontinuous be discharged automatically to the boring internal water accumulation.Unlatching that can setup control valve 6 or the time of closing, and then control is to the efflux time of the ponding in holing.
