In the Coal Production process, can form the goaf behind the seam mining, because the goaf is striden the junk leakiness space is arranged behind the roof collapse, the goaf has seeping phenomenon after a period of time, and this ponding is called as old empty water.The water accumulating volume size of the old empty water in goaf is relevant with near the water recharging degree this goaf, and old generally speaking dead zone all has ponding to exist, and long more ponding of time is many more.Old empty water is one of basic water damage of facing of mine, and the old empty water in upper strata can threaten the exploitation in lower floor coal seam, high-orderly can threaten the exploitation of low level with layer coal seam with the old empty water of layer.
It is the basic skills and the means of the empty water of anti-punish-old that spy discharges water; Spy discharges water and comprises " spy water " and " discharging water " two contents, if old dead zone is anhydrous, can carry out normal digging activity after detecting; If old dead zone has water then need take unrestrained measure with the water drainage, begin digging operation afterwards again.During spy discharges water and implements perhaps drilling towards the eminence goaf with a layer lower tunnel in the general using rig hole of drilling towards the day-coal goaf in lower floor coal road road, and therefore visiting discharging water boring basically all is to go up uphole or even vertically go up uphole.
Because goaf bottom precipitation in the ponding process has chip class thin particulate matters such as coal slime rock dust; So when visiting the boring that discharging water and getting through the unrestrained old empty water of gob floor; Let out along with under the current; The shale thing is carried gets into boring, occurs clogging so visit the port of export of the boring that discharges water in discharging water through regular meeting, and it is minimum to make old empty water can not get old empty water waterdrainage amount unrestrained or boring.
Blocked for boring, common processing method one is to utilize rig repeated multiple times open-work, with the deposit mediation, passes through boiling water stream then and discharges water; The 2nd, carry out porous through the hole of drilling more and discharge water.The problem that these two kinds of methods exist is: 1, the probing workload is big, engineering cost is high, the length that expends time in, and rig passes through perforate and removes the back if plug-hole must move back again and repeat open-work once more; 2, it is blocked that existing method and technology fail fundamentally to solve effectively boring, can not guarantee to remove the problem that current do not take place to stop up once more during boring discharges water after boring.
The utility model content:
The purpose of the utility model will provide a kind of old empty water unrestrained anti-blocking aperture apparatus of holing, with taking a lot of work of overcoming that existing method exists, time-consuming, cost is high, can not effectively solve the problem of boring plug-hole simultaneously.

The above-mentioned support ring of going up is fixedly connected on the reducing step.
Be connected with tube connector between above-mentioned biscuit cutter and the stay pipe.
Contrast can be known; Prior art is only washed the stifled shale thing of nose end open through mediation boring and by current; But because the complicated component of charges in the old dead zone has materials such as coal cinder, coal slime, rubble, rock dust, along with old empty water flows in discharging water; Current carry the shale thing and possibly compile the aperture again and stop up boring once more, and problem is manifested once again.The utility model has changed uncertainty and the low guaranteed property of prior art in solving plug-hole; Not to manage to dredge the shale thing; But propose to prevent that through pre-buried pipe the shale thing from getting into the anti-blocking method of boring, bury stay pipe in advance underground in the bottom, goaf of drill tip, and make the pre-buried pipe mouth of pipe exceed the shale layer; breakthroughly Thereby a large amount of old empty water can freely be flowed down through the high-order aperture of reproducing; The shale thing generally can not get into boring simultaneously, has reduced the possibility of the blocked water proof of holing, and has greatly increased the success rate of the unrestrained old empty water of single boring.
Compared with prior art, the following advantage of the utility model tool:
1, utilize stay pipe to do dummy hole and penetrate the shale layer, stop in the unrestrained water that the shale logistics goes into boring, it is blocked fundamentally effectively to prevent to hole;
2, adopt this method to visit and need not repeatedly open-work in the engineering that discharges water or move the brill punching again, saved drilling project amount and engineering time, greatly improved operating efficiency, reduced engineering cost;
3, this equipment mechanism is simple, is convenient to processing and fabricating;
4, this installs easy to use simple and directly, is convenient to the Field Force and manipulates;
5, this device applicability is strong, applicable to various slewing drilling machines in down-hole and drilling tool.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is at length explained.
Embodiment 1
Referring to Fig. 1-Fig. 2; The anti-blocking aperture apparatus of a kind of unrestrained boring of old empty water comprises the expanding mechanism that is provided with on drill bit 1, stay pipe 2, pipe nipple 7 and the stay pipe 2 that connects successively from top to bottom, is provided with spilled water hole and passes through thread connection between the two on drill bit 1 and the stay pipe 2; Stay pipe 1 passes through splined with pipe nipple 7; The tube wall internal diameter of stay pipe 2 is up big and down small, and transition position is provided with the reducing step, and described expanding mechanism comprises support ring 6, spring 4, following support ring 9 and linkage; Last support ring 6 is connected with the two ends of spring 4 respectively with following support ring 9; Two free ends of two linkages are fixed in support ring 6 respectively and are arranged in the vertical chute of offering on the tube wall 8 with following support ring 9, two linkages, and last support ring 6 is fixedly connected on the inwall of stay pipe 2.
In order to be provided with conveniently, last support ring 6 is fixedly connected on the reducing step in the stay pipe 2.
The above drill bit is that outer rim is the form of structure of wedge shape, can change the gradient and the thickness of drill bit during use according to the boring stopping state, stops up section so that drill bit passes smoothly;
The utility model method for using is: after spy discharges water boring whole hole withdraws from drilling rod; If the flow of old empty water is little in the boring; Or the no old empty water outflow that is blocked of holing; Can on common drilling rod, connect pipe nipple 7, then install on the pipe nipple 7 spring 4 of having packed into, support bar 5, on the stay pipe 2 of support ring 6 and play support ring 9, connection drill bit 1 on stay pipe 2 again.Because boring is to go up uphole, under the action of gravity of drill bit 1 and stay pipe 2 things such as grade, spring 4 receives force compresses, and support bar 5 closes up in chute 8.To be in this device that closes up state and put into hell, and owing to there is spline to connect between pipe nipple 7 and the stay pipe 2, can drives pipe nipple 7 after drilling rod rotates and rotate, pipe nipple 7 rotations can drive stay pipe 2 successively and rotate with drill bit 1.The normal upwards cleaning bottom of hole of beginning creeps into, because this device has drill bit 1, the boring idol has the hole of collapsing undergauge can not influence normally to creep into.Drill bit 1 gets into the plug-hole place, strengthens pump amount pump pressure and washes away the plug-hole material, and suitably increase the rig rotating speed; But creeping into feeding rate will control well; Sweep out the plug-hole thing up to drill bit 1 and get into the goaf, this moment, slush pump can pressure release, if termination of pumping and dismantle the water pigtail that is connected between drilling rod and the water pipe; Have a large amount of old empty current in the drilling rod and come out, show that the goaf and the mouth of pipe that this device has got into foreign material such as being full of water, rubble, coal slime have been higher than the shale layer.Under the extruding of shale thing, stay pipe is swept along in the shale thing, and stop to creep into this moment; Withdraw from drilling rod downwards; Spring 3 extends at once and opens support bar 5, and stay pipe 2 is fixed in the old dead zone in the foreign material such as shale thing, makes that support bar is unlikely in discharging water afterwards falls into boring.After support bar opens, progressively drilling rod is withdrawed from boring, can begin formal unrestrained water, reduce to absolute altitude place, drill bit aperture up to the water level of old empty water is dredged.Also can continue unrestrained old empty water its water level reduced to minimum spilled water hole place absolute altitude if spilled water hole all stops up this moment, and the aperture of spilled water hole is little, and having the shale thing to get in the pipe can be washed away and can plug-hole by top-down flowing water.
This device is the disposable articles for use that make, and gets into behind the goaf not recyclablely, though material has consumption, compared with manpower and materials and time cost that open-work or new punching are again consumed, overall benefit is far better.
Because the mixed and disorderly complexity of old dead zone deposit if the thickness of shale thing is bigger, can increase tube connector according to its thickness between drill bit 1 and stay pipe 2, this tube connector is that normal basket gets final product.
