Technical field

The present invention relates to a kind of gas drainage devices more particularly to a kind of for clearing up coal mine gas extraction drill hole collapse hole Device and its application method belong to coalmine ventilation equipment technical field.

Background technique

Coal mine gas is taken out in drilling construction, is influenced by factors such as geological structure, condition of coal seam occurrence, drilling construction is frequent The phenomenon that encountering weak structure country rock unstability leads to collapse hole after being disturbed by drill bit, borehole failure is caused, one-tenth porosity is lowered.Especially When being construction negative angle drilling, more water and the boring mud that cannot be discharged can be remained in foot of hole, leads to gas drainage pipeline Foot of hole cannot be descended, and a large amount of water and boring mud enter extraction pipeline in sealing of hole extraction, seriously affect gas drainage results.Mesh Preceding not mature drilling deslagging device, the slagging-off effect of pressure wind water is restricted by drilling depth, and the meeting in slag removal Secondary Disturbance is formed to drilling weak structure coal petrography, increases the probability of collapse hole.

Summary of the invention

The technical problem to be solved by the present invention is provide a kind of device for clearing up coal mine gas extraction drill hole collapse hole and Its application method, big to solve current firedamp taking-out discharging drilling slagging-off and collapse hole processing difficulty, at high cost, effect is poor, not can guarantee The problems such as gas drainage results.

The technical scheme is that a kind of for clearing up the device of coal mine gas extraction drill hole collapse hole, it includes boring mud The top of storage barrel, connecting tube and negative pressure connecting tube, the boring mud storage barrel is equipped with cover board, in the bottom sidewall of boring mud storage barrel On set out cinder notch, be respectively equipped with baffle, primary filter, secondary filter and three-stage filtration from bottom to up in boring mud storage barrel Net is fixedly connected with brings down stocks water valve, dreg inhaling pipe and adapter tube on the cover board, and dreg inhaling pipe connects opening device, adapter tube by connecting tube By negative pressure connecting tube connecting valve, valve is connected on coal mine high negative pressure gas drainage under suction main line.

The dreg inhaling pipe is inverted L shape structure, and the outlet end of dreg inhaling pipe extend into the lower section of primary filter and is located at baffle Top.

The baffle is in tilted layout and is fixedly connected with boring mud storage barrel inner wall, and the bottom end of baffle is close to slag notch.

The primary filter, secondary filter and three-stage filtration net it is horizontally disposed and with boring mud storage barrel inner wall is fixed connects It connects, primary filter mesh number < secondary filter mesh number < three-stage filtration mesh number.

It is a kind of for clearing up the application method of coal mine gas extraction drill hole collapse hole device, the method step are as follows: one, by valve Door is connected on coal mine high negative pressure gas drainage under suction main line, then by opening device connecting conduit, conduit transfer to foot of hole or At collapse hole；Two, opening device is opened, negative pressure of suction leads to the top of conduit, i.e., at drilling blocking, by pulling and pushing conduit back and forth, So that tamper enters boring mud storage barrel by connecting tube and dreg inhaling pipe；Three, tamper passes through primary filter, second level mistake respectively After strainer and three-stage filtration net filtration, tamper is blocked in boring mud storage barrel, closes valve and opening device, opening are slagged tap Mouth removes tamper, so repeats above operation, until drilling cleans up.

The beneficial effects of the present invention are: compared with prior art, using technical solution of the present invention, present apparatus construction letter Single, safe and reliable, compared to the technology of existing cleaning drilling blocking, the present apparatus is taken out by gas pumps the negative pressure generated as dynamic Power has the characteristics that easy to operate, at low cost, effect is good.
