Description
Technical field
The utility model relates to coal mine equipment, particularly a kind of mining gas discharging, coal-bed flooding integral type hole packer (or claiming to take out notes integral type hole packer, mining multifunctional hole packer).
Background technology
Along with the deep development of colliery industry, the improving constantly of management means.Small-sized accident all descends in integral body; Impact, coal conflict with gas, gas burst accident constantly takes place and large-scale accident is pressed like: ground; To phenomenon like this; Coal industry is taked following prophylactico-therapeutic measures: 1. the coal seam draws out methane: discharge the pressure that the pernicious gas in the coal seam produces through negative pressure, prevent that coal and gas burst accident from taking place; 2. fracturing: to the coal seam high pressure water injection, force the coal seam to produce the crack, increase gas permeability; Induce gas discharge in the coal seam; Reduce the coal seam internal pressure, softening coal seam and country rock reduce lithostatic stress; Effect dustproof, fire extinguishing is played in the generation that the prevention coal is outstanding with gas or the ground pressure is conflicted simultaneously again.In this case, coal-bed flooding, drawing out methane is operated in the colliery and prevents and treats major accident and take place, and seems particularly important.
The colliery industry is to these two work, and the hole that still draws out methane at present can only draw out methane, and water injection hole can only water filling, and both technologies are not related; Each oneself operation of row had not only bothered but also waste material, and labour intensity is big; Inefficiency, therefore, its improvement and innovate imperative.
Summary of the invention
To above-mentioned situation; For overcoming the defective of prior art, the purpose of the utility model just provides a kind of mining gas discharging, coal-bed flooding integral type hole packer, can effectively solve draw out methane, coal-bed flooding not only bothered but also waste material; Labour intensity is big, ineffective problem.
The technical scheme that the utility model solves is, comprises releasing pipe, antipriming pipe, air bag, extraction joint or water filling joint, and first releasing pipe is communicated with first antipriming pipe through the butt joint screw; First antipriming pipe connects second releasing pipe through the butt joint screw; Second releasing pipe connects second antipriming pipe through the butt joint screw, and second antipriming pipe connects extraction joint or water filling joint through hickey, and (the air inlet head can be contained in the antipriming pipe of air bag for air bag and air inlet head before being set with on first antipriming pipe; Also can be contained on the outer antipriming pipe of air bag; Providing the air inlet head among the figure is contained on the outer antipriming pipe of air bag), advancing has the gas tube that is connected in a fit of anger, on second antipriming pipe rear gasbag is housed; The pore of first antipriming pipe is communicated with preceding air bag through air guide port, and the pore of second antipriming pipe is communicated with rear gasbag through air guide port.
The utility model is simple in structure, and is novel unique, and one-object-many-purposes is convenient to use, high efficiency, and economical with materials has remarkable economical and social benefit.

The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
Provided by Fig. 1-4, the utility model comprises releasing pipe, antipriming pipe, air bag, extraction joint or water filling joint, it is characterized in that; First releasing pipe 1 is communicated with first antipriming pipe 10 through the butt joint screw, and first antipriming pipe connects second releasing pipe, 4, the second releasing pipes through the butt joint screw and connects second antipriming pipe 9 through the butt joint screw; Second antipriming pipe connects extraction joint or water filling joint 6 through hickey 3; Air bag 2 and air inlet 7 (the air inlet head can be contained on the antipriming pipe in the air bag, also can be contained on the outer antipriming pipe of air bag, provides the air inlet head among the figure and is contained on the outer antipriming pipe of air bag) before being set with on first antipriming pipe; Advance the gas tube 8 that is connected is arranged in a fit of anger; The pore 11a that rear gasbag 5, the first antipriming pipes are housed on second antipriming pipe is communicated with preceding air bag through air guide port 13a, and the pore 11b of second antipriming pipe is communicated with rear gasbag through air guide port 13b.
Described first antipriming pipe is the identical round tube of structure with second antipriming pipe; The round tube inwall has (have one or more passage at least and be parallel to big tube's axis) pore 11 (being pore 11a or 11b) and the medium holes 12 (being medium holes 12a or 12b) that links together with inwall respectively; Pore constitutes inlet channel; Medium holes constitutes medium channel, and interstitial hole constitutes and draws out methane or waterflood path.
The pore two ends of described first antipriming pipe are filled with shutoff material 14, and (or an end has the shutoff material; Unidirectional gas tube in the other end mounting pipe), constitute the sealing venting channels, the pore 11b of second antipriming pipe and medium holes 12b one end have shutoff material 17; Form ventilation or medium channel; The other end of pore 11b has inflation one way valve 16, and the other end of medium holes 12b has fast interface, and row's overflow lip 15 is arranged on the medium channel that medium holes 12b constitutes.
The working condition of the utility model is the utility model to be inserted in the extraction hole selected appropriate location; When the extraction hole is the nutation hole, behind the air bag, that the gap between releasing pipe and the hole wall is airtight before opening with air-compressed gas; Through the fast interface of rear gasbag, inject closed dielectric and get final product, open rear gasbag with air-compressed gas then; Prevent that medium is excessive, hole-sealing technology just is through with, and loading onto the gas drainage under suction head just can extraction; Behind the gas drainage under suction end-of-job, unload the gas drainage under suction head change the water filling joint just can water filling; After the extraction hole is when going up uphole, opens rear gasbag with air-compressed gas, that the gap between releasing pipe and the hole wall is airtight; Through the fast interface of rear gasbag, inject closed dielectric, open preceding air bag with air-compressed gas then; Prevent that medium from overflowing before excessive, the sealing of hole operation just is through with, and loading onto the gas drainage under suction head just can extraction; Behind the gas drainage under suction end-of-job, unload the gas drainage under suction head change the water filling joint just can water filling.
Can find out that by above-mentioned situation the utility model has realized that a hole is dual-purpose, has reduced the punching number, can draw out methane and can be to coal-bed flooding; Integrate and draw out methane and water-filling function, very easy to use quick, through on probation and test, but economical with materials 50%; And greatly reduce loaded down with trivial details punching labour intensity, and reduced the probability that kills drilling rod in coal seam punching, practiced thrift cost; Improved operating efficiency, saving of work and time, economic and social benefit is remarkable.
