Abstract
The invention provides a coal mine drilling blowout preventer comprising an orifice casing. A blowout preventing shutter is fixedly connected to the top of the orifice casing through flanges, and each of two ends of the blowout preventing shutter is connected with a wheel disc through a lead screw. The coal mine drilling blowout preventer is reasonable in structure, small in size, high in strength and high in safe reliability. By the adoption of two blowout preventing facilities, sealing property and blowout preventing effect are good, and sudden blowout of water or gas coal dusts can be prevented. The coal mine drilling blowout preventer using the flanges for connection is simple to operate and convenient to demount and maintain, and the upper and lower two blowout preventing facilities can be detached and used individually.
Description
Technical field
The present invention relates to the Coal Mining Technology field, be specifically related to the device that a kind of coal mine down-hole drilling prevents water in coal seam or gas ejection.
Background technology
In process of coal mining, due to complicated geology, contain a large amount of gas or water in some coal seams, affected the normal exploitation in colliery, therefore first need boring carry out extraction or water is discharged gas before coal mining.When rig creeps under coal mine, when running into coal seam gassy, invar this be inflammable and explosive gas, can, from boring China and foreign countries spray, to Safety of Coal Mine Production, great threat be arranged; And, when running into the coal seam that water content is large, have a large amount of water or coal slurry to spray from aperture, worsened operating environment, and constructor's personal safety has also been had to certain threat; When serious, when the water yield sprayed is larger, limited by drainability, can flood the production of ，Gei colliery, tunnel and cause heavy economic losses.Water logging tunnel or work plane and the drilling gas burst explosion accident that occurs now and then, had a strong impact on the safety problem of the normal exploitation in colliery.For fear of the generation of this type of accident, mostly at drilling orifice, blowout hookup is installed so that in the situation that burst by gases at high pressure or liquid in the blowout hookup control hole in aperture, spray outward.But the blowout hookup function of using at present is too simple, only around drilling rod, wrap up a circle rubber ring, can prevent that a part of water is sprayed onto hole external, once but hydraulic pressure is excessive, the sealing of the rubber ring that can conflict, and its blowout prevention effect is undesirable.
Summary of the invention
The present invention will solve above-mentioned deficiency exactly, and the blowout hookup that when a kind of effective underground boring construction is provided, boring water outlet and gas ickings are gushed out, for the drilling construction personnel provide the operating environment of a safety, is guaranteed the safety of constructor in drilling operation.
In order to reach above-mentioned effect, the invention provides a kind of coal mine drilling blowout hookup, comprise orifice sleeve, described orifice sleeve top is connected with the blowout prevention flashboard by flange, and the two ends of described blowout prevention flashboard are connected with wheel disc by screw mandrel.
Described blowout prevention flashboard periphery is provided with sealing ring.
Described blowout prevention flashboard upper end is provided with the blowout prevention pad, and described blowout prevention pad top is provided with the gland of fastening blowout prevention pad.
In order further to strengthen the effect of blowout prevention, prevent that a small amount of gas or liquid from spraying by flashboard, the present invention also can be provided with weep pipe in described blowout prevention flashboard upper end, and described weep pipe and described blowout prevention flashboard are affixed by flange.
Described weep pipe upper end is provided with the blowout prevention pad, and described blowout prevention pad top is provided with the gland of fastening blowout prevention pad.
Described weep pipe be two symmetrically arranged, weep pipe is provided with valve.
Device for preventing blowout of drill holes of the present invention is provided with upper and lower twice blowout prevention facility, first be flashboard to the cassette blowout prevention, second is the release blocking type.Select this twice blowout prevention facility according to the geology characteristic in boring place, as water content in coal seam or gas amount, when fewer, the one blowout prevention facility that can be used alone gets final product; If measure when larger, twice blowout prevention facility will be used simultaneously, and the effect of blowout prevention is better.
When using, first the first flashboard is fixed on the orifice sleeve of drilling orifice by flange cassette blowout prevention facility, then connects second release blocking type blowout prevention facility by flange.And when hole water outlet or gas are emerged, by two ends wheel disc rotary screw, screw mandrel drives flashboard radially to central motion, makes the flashboard fluid sealant clamp drilling rod, thereby annular space is realized to sealing, the water yield of boring or an outstanding watt fusain bits amount are reduced to more than 99%.Have a small amount of water or ickings to gush out from flashboard and drilling rod gap, entered the second release and stopped in the blowout prevention facility, spray a small amount of water or ickings and just flow away from weep pipe, and that the blowout prevention on its top is lined with gland is fastening, avoided air-flow etc. to release from here.Through twice, blowout prevention can realize the blowout prevention technology requirement of boring substantially, thereby has guaranteed bore operation environment and staff's safety.
The present invention compared with prior art has following benefit:
1, the present invention is rational in infrastructure, volume is little, intensity is high, security reliability is strong;
2, because it connects by flange, it is simple to operate, dismounting is easy to maintenance, and the removable independent use of upper and lower two cover blowout prevention facility;
3, two cover blowout prevention facilities, its sealing performance and blowout prevention are effective, the prominent spray of waterproof or gas ickings;
4, anticorrosive, oil resistivity, resistance to acids and bases are strong, long service life.
