Abstract
The utility model relates to a device for drill hole construction under a coal mine shaft, in particular to a hole-sealing pipe and hole device for a drill hole with kilometer depth, which solves the technical problem that a pipe section of a high gassy mine shaft for sealing a drill hole with the kilometer depth is easily blocked. The hole-sealing pipe and hole device structurally comprises a hole-sealing pipe with length of 6 inches located in the gas drill hole, the hole-sealing pipe is externally connected with a four-way joint with hole diameter of 6 inches, and the four-way joint with the hole diameter of 6 inches is externally connected with a four-way joint with the hole diameter of 4 inches. An upper-end pipe hole of the four-way joint with the hole diameter of 6 inches and an upper-end pipe hole of the four-way joint with the hole diameter of 4 inches are respectively provided with pipelines connected with a main pumping pipeline, a lower-end pipe hole of the four-way joint with the hole diameter of 6 inches is connected with a gas-water separating device pipeline, and a lower-end pipe hole of the four-way joint with the hole diameter of 4 inches is closed. The hole-sealing pipe and hole device is simple in structure reasonable in design and good in using effect. An accident of overloaded gas due to the fact that the drill hole with the kilometer depth is blocked is avoided.
Description
Technical field
The utility model relates to a kind of coal mine down-hole drilling construction and uses device, is specially a kind of km drilling and sealing pipe and opening arrangement.
Background technology
4 cun PVC hole sealing tubes are adopted in km boring without exception in the work progress before wellblock, east, Si He ore deposit and western wellblock, and effect all shows well.But in the process in the 1# hole of in the 0802 km drill site of Westbound, constructing; Gas pressure big (move back bar accomplish to extract gas scale out be 37m3/min after measure this boring) in the hole when moving back bar; The aperture connects 3 times 4 cun negative pressure pipes and still fails to satisfy the demand, and repeatedly causes return gas exceeding limit accident.At the bottom of moving back bar to hole, during motor (exposing 1.5 meters), the crown drill phenomenon takes place, motor is withstood on the rig, can't draw off.Find that through after the on-site inspection km boring adopts 4 cun pvc pipes to carry out sealing of hole, but the bit diameter that my ore deposit km rig adopts is 96mm; The hole sealing tube caliber is too little, and when bit part retreated to the sealing of hole pipeline section, the space was very narrow and small between drill bit and the hole sealing tube; Be merely the annulus of 1mm, cinder can be easy to accumulate in drill bit and the hole sealing tube narrow space in the hole, if the cinder gathering is too much; When especially the dirt band phenomenon being arranged in the work progress; When the slag that returns out was the bulk cash, the aperture was stopped up and will often be taken place, and cinder is easy to the aperture is blocked in the hole.Gas gathers manyly more more in the hole, and pressure can increase gradually, when increasing to a certain degree, also can cause spray orifice, and the constructor is constituted safety hazard.
Summary of the invention
The utility model provides a kind of km drilling and sealing pipe and opening arrangement in order to solve the technical problem of highly gassy mine km drilling orifice sealing of hole pipeline section easy blocking.
The technical scheme that realizes the utility model is; A kind of km drilling and sealing pipe and opening arrangement, structure comprise six cun hole sealing tubes that are positioned at gas boring, are externally connected with six person's pulses on the wrist footpath four-way at hole sealing tube; Six person's pulses on the wrist footpath four-way is externally connected with four person's pulses on the wrist footpath four-way; Six person's pulses on the wrist footpath four-way is respectively equipped with the pipeline that is connected the extraction main line with the mouth of pipe of four-way upper end, four person's pulses on the wrist footpath, and six person's pulses on the wrist footpath four-way lower port is for connecting the moisture trap pipeline, the mouth of pipe sealing of four-way lower end, four person's pulses on the wrist footpath.
Compared with prior art, it is 160mm that the utility model adopts external diameter, and internal diameter is that the PE160 pipe of 140mm carries out sealing of hole, and diameter is that drill bit and the spatial volume between the hole sealing tube of 96mm is original 60 times.When drill bit retreated to the sealing of hole pipeline section, water in the hole and cinder can be discharged smoothly.Even in work progress, the situation that can effectively avoid the aperture to stop up when running into dirt band takes place.And increased the four-way in one six person's pulse on the wrist footpath, linked to each other by PE160 hole sealing tube in six cun four-ways and the hole, then; Four cun four-ways are connected with six person's pulses on the wrist footpath four-way by reducing; Increase a four-way, increased by the four cun armouring pipes in a place again accordingly and inserted the extraction main line, four cun four-way end openings are subsequent use mouthful.Impurity such as the cinder spoil that produces in the drilling process are just separated at six cun four-ways, the effect that four person's pulses on the wrist footpath four-way also still plays sealing drilling rod endways and derives methane gas.
The utility model is simple in structure, and is reasonable in design, and result of use is good.When the boring of wellblock, west, Si He ore deposit 0802 drill site construction 2# km, used the said device of the utility model, construction finishes until the 2# hole, and the aperture phenomenon of blocking did not take place one time.Nearly 100 borings of constructing altogether of this zone do not take place in the via hole and the aperture phenomenon of blocking again, even there are a large amount of dirt bands not stop up the aperture in the drilling construction process, have thoroughly stopped to stop up the accident that causes gas exceeding limit because of the km drilling orifice yet yet.
Description of drawings
Fig. 1 is the structural representation of the utility model
Fig. 2 is the A-A sectional drawing of Fig. 1
Among the figure: 1-four person's pulses on the wrist footpath four-way, 2-six person's pulses on the wrist footpath four-way, 3-connect moisture trap pipeline, six cun hole sealing tubes of 4-, 5-coal body, 6-pipeline, 7-pipeline, 8-drill bit.
The specific embodiment
Meaning as shown in Figure 1; A kind of km drilling and sealing pipe and opening arrangement, structure comprise six cun hole sealing tubes 4 that are positioned at gas boring, are externally connected with six person's pulses on the wrist footpath four-way 2 at six cun hole sealing tubes 4; Six person's pulses on the wrist footpath four-way 2 is externally connected with four person's pulses on the wrist footpath four-way 1; The mouth of pipe of six person's pulses on the wrist footpath four-way 2 and four-way 1 upper end, four person's pulses on the wrist footpath is respectively equipped with pipeline 6,7, six person's pulses on the wrist footpath four-way 2 lower port that are connected the extraction main line and is the four-way 1 lower end mouth of pipe sealing of connection moisture trap pipeline 3, four person's pulses on the wrist footpath.
