Description

One is bowed hole drainage arrangement

Technical field

This utility model relates to mine deslagging technical field of drainage, is specifically related to one and bows hole drainage arrangement.

Background technology

Coal mine underground construction relates to gas drainage under suction, and hole of bowing in construction drill is more, and hole internal water accumulation affects gas drainage under suction effect, Affect extraction pipeline gas density, the pore volume water of bowing of boring need to be discharged, to improve mine gas drainage effect, it is ensured that boring is just Often use.

Shanxi Luan Group Yuwu Coal Co., Ltd. proposes utility model patent: ZL201320027859.2 " To the hole deslagging drainage arrangement of bowing of boring under Zhong ", the pore volume water of bowing of boring can be discharged, have certain effect, but also have not in application Foot.

The hole drainage arrangement of bowing of prior art, in actual use, defective existence, and need to be improved.This practicality The defect of hair person of good sense's thoughts prior art can be improved, and spy concentrates on studies and coordinates repetition test, finally proposes one design Rationally and be effectively improved the utility model of prior art defect.

Summary of the invention

This utility model technology is, for mine gas drainage problem, effectively to discharge the pore volume water of bowing of boring, it is ensured that ore deposit The normal table that mountain produces.

The technical solution of the utility model is:

One is bowed hole drainage arrangement, and it is described that it includes that air pipe, sealing of hole bar, upper drain pipe, lower drain pipe is characterized in that Air pipe one end is uncovered, other end iron plate welded seal, and there is osculum at iron plate center, welded nut outside osculum, spiral shell Mother is furnished with bolt, welds described upper drain pipe inside osculum, and air pipe opening end connects flexible pipe and is socketed with described sealing of hole bar； Air pipe is further connected with arm of calming the anger, and arm of calming the anger is equipped with snap joint and valve；Described upper drain pipe, lower drain pipe are placed in In air pipe and sealing of hole bar, lower drain pipe lower end has sieve aperture, upper drain pipe, lower drain pipe to have adapter to be connected.

This utility model carries out draining for hole of bowing extraction borehole, quickly the connecing on arm of calming the anger of air pipe during use Head accesses pressure wind by high-pressure rubber pipe, and pressure wind enters sealing of hole bar through air pipe, and boring internal water accumulation pressurized wind pressure acts through down Drain pipe, upper drain pipe are discharged, and after boring hydrops is drained, close pressure air valve, screwing bolts.

This utility model once can discharge multiple boring hydrops, saves boring water discharge time.During draining, by brill It is continuing to supply pressure wind in hole, and can grasp whether drilling and sealing leaks gas in time, check sealing quality, cut bulge test simultaneously Step.Whether hydrops can be had in simplicity, fast decision boring.The equipment that this utility model uses can reclaim, recycling. Substantially increase gas drainage under suction concentration after using this utility model, shorten the gas drainage under suction time, decrease gas control impact The engineering time of mining operation.

This utility model is applicable to mine deslagging technical field of drainage.

Detailed description of the invention

Embodiment 1:

The hole draining of bowing of the extraction borehole of certain coal industry company have employed this utility model, the hole draining dress as it is shown in figure 1, one is bowed Putting, it includes that air pipe 1, sealing of hole bar 2, upper drain pipe 3, lower drain pipe 4 is characterized in that described air pipe 1 one end is uncovered, Other end iron plate 5 welded seal, there is osculum at iron plate 5 center, welded nut 6 outside osculum, and nut 6 is furnished with bolt 7, row Welding described upper drain pipe 3 inside water hole, air pipe 1 opening end connects flexible pipe 8 and is socketed with described sealing of hole bar 2；Air pipe 1 is also It is equipped with arm 9 of calming the anger, arm 9 of calming the anger is connected to snap joint 10 and valve 11；Described upper drain pipe 3, lower drain pipe 4 are placed in In air pipe 1 and sealing of hole bar 2, lower drain pipe 4 bottom has sieve aperture, upper drain pipe 3, lower drain pipe 4 to have adapter 12 to be connected.

Embodiment is as in figure 2 it is shown, air pipe 1 is processed by Ф 50mm coating steel pipe, and it on, welding Ф 19mm calms the anger arm 9, Calm the anger and be connected to 10mm snap joint 10 and valve 11 on arm 9, connect 10mm snap joint 10 with Ф 10mm high-pressure rubber pipe, with pressure wind Device is connected, and is used for accessing pressure wind, can provide blast to multiple drainage arrangements as shown in Figure 2.Air pipe 1 open at one end, another End is with iron plate 5 welded seal, and the osculum setting Ф 16mm is stayed at iron plate 5 center, and welds the nut 6 of Ф 16mm, and row is used in inner side Water pipe 3(4 divide coating steel pipe) weld with iron plate 5 center preformed hole, nut 6 is connected with the bolt 7 of Ф 16mm, it is ensured that Air tight.Air pipe 1 is connected flexible pipe 8 with sealing of hole bar 2 with Ф 50mm and is connected, and connects flexible pipe 8 external iron wire colligation, and often holds colligation Number of channels is no less than 4 circles, it is ensured that air tight and de-by pressure wind pressure punching during draining.Lower drain pipe 4 uses 4 points of 3800mm length Pvc pipe, lower drain pipe 4 one inserts away from about 1m at the bottom of drilling hole, and the 4 points of pvc pipes of joint at the bottom of hole need to process sieve aperture, and one with upper Drain pipe 3(coating steel pipe) connect, between be connected with Ф 20mmPE adapter 12, and carry out colligation with thin wire.Boring hydrops After drained, close this drainage arrangement, open valve 11 and can carry out gas drainage under suction.

Can suppress with this utility model drainage arrangement and test envelope, be tightened by Ф 16mm bolt 7 after drained water, valve 11 continues Close, then supply pressure wind in boring, when pressing the malleation table on wind manifold head show to reach 0.2～0.3mpa, close and press Becalm only voltage supply, if pressure can keep pressure not decline, illustrate that drilling and sealing effect is preferable, if pressure declines, brill be described Hole sealing of hole gas leakage, need to re-start sealing of hole.

From in December, 2014, my company starts trial edition utility model drainage arrangement hole of bowing extraction borehole and arranges Water, and irregularly joined a regular shift or class by management personnel and implement this work, by before draining with draining after boring actual measurement gas density analysis, Using this drainage arrangement to substantially increase gas drainage under suction concentration, its increase rate is 3～50%.Particularly under five exploiting field return air The go down the hill hole using effect of bowing of construction of mountain, adhesive tape is more obvious, five exploiting field gas total arm gas density from 5% to bringing up to 15% to 18%.Five three, exploiting fields every cyclic advance of going down the hill improves about 60m from about 20m, saves drilling construction expense 800,000.
