Abstract
The utility model discloses a kind of geomantic omen converter, comprise supervisor, two arms are connected on supervisor top, article one, arm is extraction link, another arm is geomantic omen link, and on two arms connection control switch, after the utility model adopts the use of extraction geomantic omen converter, from original two or three classes even the more time be reduced to only need within 30 minutes to 40 minutes, just can solve gas release problem, draw out methane concentration between 15 ﹪ to 20 ﹪ through actual measurement, again quarrel mouth yellow mud is shut and then carried out extraction, gas drainage results is more obvious, accelerate construction speed and improve worker's efficiency.
Description
Technical field
The utility model relates to a kind of geomantic omen converter, belongs to coal seam technical field of construction.
Background technology
Guizhou is rich in a large amount of coal resource, and right most of colliery is all that high methane is projecting coal bed, and because ore deposit coal seam gas-bearing capacity is large, in work progress, bit freezing, crown drill phenomenon are very serious, cause great difficulty to construction.
Summary of the invention
The purpose of this utility model is: provide a kind of geomantic omen converter, and the method is mainly improved rig geomantic omen tail, realizes geomantic omen tail and extraction end can be changed mutually, realizes the object of pressure release, to overcome the deficiencies in the prior art.
The technical solution of the utility model
A kind of geomantic omen converter, comprises supervisor, and connect two arms on supervisor top, an arm is extraction link, and another arm is geomantic omen link, and on two arms connection control switch.
In the converter of aforesaid a kind of geomantic omen, supervisor arranges air pressure test point.
Owing to adopting technique scheme, compared with prior art, after the utility model adopts the use of extraction geomantic omen converter, suction arm negative pressure is utilized to carry out the gas release problem in the boring of deep hole extraction solution to boring, from original two or three classes even the more time be reduced to only need within 30 minutes to 40 minutes, just can solve gas release problem, draw out methane concentration between 15 ﹪ to 20 ﹪ through actual measurement, again quarrel mouth yellow mud is shut and then carried out extraction, gas drainage results is more obvious, accelerates construction speed and improves worker's efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing to the utility model with being described in further detail, but not as to any restriction of the present utility model.
Embodiment of the present utility model: a kind of coal seam deslagging construction method, wind deslagging or water deslagging mode is adopted to construct, large when running into coal-bed gas pressure, when construction is not entered or is not returned water, rig is shut down, close air intake water end (W.E.), geomantic omen converter other end extraction end is connected on extraction arm, gate valve is opened, be connected with extraction arm negative pressure, quarrel mouth yellow mud is shut simultaneously, utilize the negative pressure in extraction arm to carry out deep hole extraction to the boring of Hot work in progress, gas pressure in boring is discharged.
A kind of geomantic omen converter needed for said method, as shown in drawings, comprises supervisor 1, supervisor 1 arranges air pressure test point 4, connects two arms, 2, arm 2 on supervisor 1 top for extraction link, another arm 2 is geomantic omen link, and on two arms 2 connection control switch 3.
During concrete use
In construction, wind deslagging or water deslagging mode is only adopted to construct in advance, large when running into coal-bed gas pressure, when construction is not entered or is not returned water, rig is shut down, close air intake water end (W.E.), geomantic omen converter other end extraction end is connected on extraction arm, gate valve is opened, be connected with extraction arm negative pressure, " Four proofings apparatus " slag outlet yellow mud simultaneously my team now used is shut, the negative pressure in extraction arm is utilized to carry out deep hole extraction to the boring of Hot work in progress, gas pressure in boring is discharged, facts have proved, carrying out boring release at employing geomantic omen converter only needs normally intermittently to construct for 30 minutes to 60 minutes, solve bit freezing in boring, crown drill and do not return water problems, detect at the measuring point on the converter of extraction geomantic omen simultaneously, when deep hole extraction is carried out to boring, gas density can reach 60% ~ 80%.
After adopting the use of extraction geomantic omen converter, suction arm negative pressure is utilized to carry out the gas release problem in the boring of deep hole extraction solution to boring, from original two or three classes even the more time be reduced to only need within 30 minutes to 40 minutes, just can solve gas release problem, draw out methane concentration between 15 ﹪ to 20 ﹪ through actual measurement, shut slag-drip opening with yellow mud again and carry out extraction, gas drainage results is more obvious.Accelerate construction speed and improve worker's efficiency.
Wind deslagging or water deslagging mode is only adopted to construct, large when running into coal-bed gas pressure, when construction is not entered, rig is shut down, closes air intake water end (W.E.), geomantic omen converter other end extraction end is connected on extraction arm, gate valve is opened, be connected with extraction arm negative pressure, utilize the negative pressure in extraction arm to carry out deep hole extraction to the boring of Hot work in progress, gas pressure in boring is discharged.
