Description

A kind of method of the wind and water combined spray for dust suppression of tunneling working face in tunnel
Technical field
The present invention relates to the dust collection method in a kind of tunnel, be specifically related to the wind and water combined spray for dust suppression of tunneling working face in a kind of tunnelMethod, belong to dust removing down-hole technical field.
Background technology
The construction of safety quality standard construction, the dustproof management work in down-hole seems more and more important, along with digging operation machineryImproving constantly of change degree, in the daily production process of getting working face, the return airway in tunnel is the main place of dust pollution.The wind and water combined spray dust remover that mine roadway the most often adopts at present, its principle is the purification that utilizes atomization flow distinguished and admirable to dust-ladenEffect, eliminates the dust in distinguished and admirable, but the defect of this method is, and 1, atomization flow disperses, and be subject to blast and tunnel endThe impact of face, control range is limited, and therefore dust removing effects is poor; 2, coverage is little, easily causes tunnel internal water accumulation, gives peaceThe management of total quality standardization effort has brought certain difficulty.
Summary of the invention
For addressing the above problem, the invention provides the method for the wind and water combined spray for dust suppression of tunneling working face in a kind of tunnel, atomization effectGood, the dedusting broad covered area of fruit, can not cause tunnel internal water accumulation.
To achieve these goals, in a kind of tunnel, the method for the wind and water combined spray for dust suppression of tunneling working face, comprises the steps:
1), driving face meet head on 50~150m place install one purification water curtain device; Purification water curtain device with anchor rod anchored in laneTop board place, road, and purification water curtain device is not less than 2000mm apart from roadway floor.
2), digging laneway length exceedes after 200 meters, and one Dust collecting net is being installed apart from return air inlet 30m place; Install Dust collecting net topThere is atomising device;
3), per pass purification water curtain device, Dust collecting net below are equipped with gutter.
Purification water curtain device coordinates Dust collecting net can effectively tackle coal dust, the atomising device shape that purification water curtain and Dust collecting net upper end arrangeBecome three-dimensional staggered form depositing dust, guarantee all standing of whole drift section; Ponding is thoroughly discharged by gutter, can not cause in tunnelPonding.
Further, one automatic sprayer of blasting installed at the gun diging face 100m place that meets head on, and blows out auto spraying in distanceOne purification water curtain device installed at device 10~50m place, front.
Further, fully mechanized workface meet head on 50m place install one purification water curtain device, dedusting fan is located on development machine.
Because tunneling method is mainly divided into big gun pick and combines pick, according to different tunneling methods, described purification water curtain device position is setPut difference, make dust removing effects reach optimum.
Further, between purification water curtain device and Dust collecting net, be provided with another road purification water curtain device, the jet flow of purification water curtain deviceDirection is all towards return air inlet direction.
Preferably, Dust collecting net comprises fixed Dust collecting net and pullable type Dust collecting net, and atomising device comprises supervisor and atomizer, mainPipe is made according to the bending curvature in tunnel, and supervisor is by short anchor rod anchored on back, and fixed Dust collecting net is connected to supervisorNegative camber on, on supervisor, evenly have some apertures, atomizer is fixed on each aperture place and towards fixed Dust collecting net sideTo; The sealing of supervisor one end, the other end communicates with water inlet pipe by feed pipe, control valve; Pullable type Dust collecting net is opening and closing type knotStructure, its two ends are fixed on lane by short anchor pole and help, and its upper end cover is connected on stay cord.
When use, current flow into the supervisor of atomising device through water inlet pipe, are then sprayed by atomizer, mist in the effect of hydraulic pressureChange flow direction Dust collecting net, be covered with the uninterrupted tiny globule and the tax on Dust collecting net, current are evenly easy to control, and clean-up effect is brightAobvious; In Dust collecting net, pullable type Dust collecting net can be pulled to both sides along stay cord, forms personnel's porte-cochere, in the time of working surface production,Again pullable type Dust collecting net is closed, both ensured can also effectively filter the coal dust of working face when pedestrian passes through.
Dust collecting net can also adopt form, the form of switch hinge etc. of roller shutter, the preferred Dust collecting net structure of the present invention, on the one handSimple in structure being easy to realized, easy installation and removal on the other hand. Dust collecting net can utilize anchor cable to be made into flexible metal net, removesAfter can reuse, the size of grid according to practical application determine, scene can increase and decrease the skeleton of Dust collecting net at any time.
Further, purification water curtain device comprises shower nozzle and geomantic omen pipe, and shower nozzle is made up of the steel pipe of closed at both ends, the tube wall of shower nozzleOn have some apertures, on one of them hole, connect geomantic omen pipe, described geomantic omen pipe is Y shape steel tube, on the bifurcated pipe of Y shape steel tubeConnect high-pressure air hose and high-pressure water pipe 5 by snap joint respectively.
The high-pressure blast and the water under high pressure that separate are sprayed by atomizer after one section of shared geomantic omen pipe, have further strengthened atomization effectReally. Shower nozzle and geomantic omen pipe process by waste and old steel pipe, along with the extension in tunnel can be dismantled and recycle at any time, have savedProduction cost.
Preferably, the supervisor of atomising device adopts six points of steel pipes, and the spacing of every two atomizers is 300mm; Pullable type is caughtThe height of dirt net is not less than 2000mm. Atomizer can adopt caliber to be not more than the tubule of 5mm, and delivery port is rounded orPerson's pancake.
Preferably, the caliber of shower nozzle is 100~110mm, geomantic omen pipe adopts six points of steel-pipe weldings to form, aperture on shower nozzle tube wallAperture is 3mm, and pitch-row is 10~15mm, and stop valve is all installed in high-pressure air hose and high-pressure water pipe.
Six points of tube qualities are lighter, are convenient to dismounting mobile; The air quantity of high-pressure air hose and the water yield of high-pressure water pipe be by stop valve control,Simple to operate, convenient adjusting.
The present invention purifies the dust-laden in mine laneway is distinguished and admirable, elimination dust that can all standing; The setting of Dust collecting net simultaneouslyDo not affect personnel in lane and pass through, the current after purification are thoroughly discharged by gutter, discharge also reusable edible of water; Structure of the present inventionSimply, cost-saving, and easy installation and removal, the scope of application is wider.
