Abstract
The utility model discloses a drainage drill hole anti-gas device of an outburst mine. The drainage drill hole anti-gas device of the outburst mine comprises a dust-falling box, a gas collecting tube, a connecting tube and a gas coal collecting box. A dust-releasing opening is arranged on the lower end of the dust-falling box, a coal-releasing opening is arranged on the lower end of the gas coal collecting box, the dust-falling box is communicated with the gas coal collecting box through the connecting tube, and the gas collecting tube is connected with the upper right portion of the dust-falling box through a valve. A dust-stopping screen is fixedly arranged inside the dust-falling box in inclined mode, right space of the dust-stopping screen is communicated with the connecting tube and the gas collecting tube, left space of the dust-stopping screen is provided with an exhaust tube, and the exhaust tube is connected with an underground gas drainage pipeline. The drainage drill hole anti-gas device of the outburst mine can not only prevent gas outburst from causing accidents to operating personnel in the process of drilling, but also solve the problems that drilling dust pollutes environment and gas exceeds a limit.
Description
Technical field
The utility model relates to and belongs to the anti-gas spray orifice of the projecting mine extraction borehole technical field that transfinites.
Background technology
Along with the increase year by year of China's coal-mine mining depth, the quantity of coal and gas outburst mine also increases year by year.The essential measure that solves mine coal and gas outstanding problem is the extraction coal-bed gas, no matter is to wear in layer mash gas extraction boring or the process along the boring of layer mash gas extraction in construction, and the situation of high pressure gas spray orifice usually can take place.The gas spray orifice of weak intensity can cause the tunnel gas exceeding limit, exists to cause gas explosion accident hidden danger; The cinder that high-intensity gas spray orifice carries also can cause the personal injury accident of " object strike " class to the constructor.The coal dust of ejection can cause dust harzard, worsens the worker laboring environment.The processing method that mine is commonly used is to strengthen the ventilation of construction tunnel, and dilution gas prevents gas exceeding limit; The operating personnel departs from drilling orifice drilling rod direction, avoids object to hit injury; Increase dustproof water curtain or use dust arrester, reduce dust concentration, reduce dust harzard.After taking these measures, obtain certain effect, but do not tackle the problem at its root.
The utility model content
The purpose of the utility model provides and a kind ofly can prevent effectively that the gas spray orifice causes the accident in the process of drilling, and can solve the anti-gas device of the dustproof projecting mine extraction borehole of drilling.
To achieve these goals, the utility model comprises: depositing dust case, discharge, tube connector, gas collection coal bin are provided with in depositing dust case lower end and put the dirt mouth; Be provided with coal discharge outlet in gas collection coal bin lower end; Be communicated with by tube connector between depositing dust case and the gas collection coal bin, be connected with discharge through valve, be set with resistance dirt screen cloth in depositing dust case inner inclination at depositing dust case upper right quarter; Resistance dirt screen cloth rightward space is communicated with resistance with tube connector and discharge
Dirt screen cloth leftward space is provided with exhaust tube, and exhaust tube is connected with the fire damp extraction pipeline.
Described screen cloth leftward space top is provided with firedamp sensor and drencher head, and drencher head is connected with water inlet pipe.
Like this, in the process of drilling, the gas collection coal bin is fixed on drill hole; Exhaust tube is connected with fire damp extraction negative pressure line, and drilling rod passes the gas collection coal bin through sealing ring and punches, and gas and ickings are gushed out along drilling rod in the punching process; Ickings falls into gas collection coal bin bottom; Gas gets into the screen cloth rightward space through tube connector, after resistance dirt screen cloth further purifies, is discharged by exhaust tube.Need the freezing period of certain hour for sealing of hole medicament behind the sealing of hole with cement paste and can't be connected with negative pressure extraction system immediately the time, can the discharge on screen cloth rightward space top be connected on the extraction pipe of sealing, be used to discharge the gas of gushing out in the sealing of hole extraction pipe.Can prevent that the gas spray orifice causes the accident to operating personnel in the process of drilling, can solve drill dustproof contaminated environment and gas exceeding limit problem again.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain.
Fig. 1 is the on-the-spot mounting structure sketch map of the utility model.
The specific embodiment
Can know that by Fig. 1 the utility model comprises: depositing dust case 1, discharge 7, tube connector 9, gas collection coal bin 13.Be provided with in depositing dust case 1 lower end and put dirt mouth 17, be set to insert formula coal breakage plate, be used for regularly removing the coal dust that falls in the depositing dust case 1.Be provided with coal discharge outlet 12 in gas collection coal bin lower end, be set to insert formula coal breakage plate, be convenient to regularly remove the boring ickings.Be provided with sealing ring 14 in gas collection coal bin 13 left sides, when drilling rod 15 punches, prevent that gas from spilling on rib 10.Be communicated with by tube connector 9 between depositing dust case 1 and the gas collection coal bin 13.Also be connected with discharge 7 at depositing dust case 1 upper right quarter through valve 6, do not solidify good and can't be connected with negative pressure extraction system immediately the time, can discharge 7 be connected to envelope for sealing of hole medicament behind the sealing of hole
On the good extraction pipe 8, open valve 6, be used to discharge and take out the gas of gushing out in the hole in advance.Be set with resistance dirt screen cloth 18 in depositing dust case 1 inner inclination, resistance dirt screen cloth 18 rightward space are communicated with tube connector 9 and discharge 7, and resistance dirt screen cloth 18 leftward space are provided with exhaust tube 2, and exhaust tube 2 is connected with the fire damp extraction pipeline.Resistance dirt screen cloth 18 leftward space tops are provided with firedamp sensor 3 and drencher head 5, and drencher head is connected with water inlet pipe 4.Firedamp sensor 3 can be connected to the mine gas monitoring system, and the real time on-line monitoring gas density according to the situation that gas density changes, is judged the gush out size of intensity of boring 11 gas, combines the degree of depth of boring 11, judges the generation gas unusual position that gushes out.Water inlet pipe 4 can be connected to the dustproof water lines in down-hole, is used for regularly cleaning resistance dirt screen cloth 18 and guarantees that gas circuit is unimpeded.During on-the-spot actual the use, depositing dust case 1 is placed on the ground 16, and gas collection coal bin 13 is fixed on drill hole, utilize the utility model can be simultaneously to construction drill and sealing of hole gas suction by drilling in advance.
