Description
Technical field
The utility model relates to a kind of speedy drivage device of coal and gas outburst mine work plane, little jet control coal of particularly a kind of high pressure and the outstanding device of gas.
Background technology
In the tunneling process of coal and gas outburst mine work plane, the measure that conventional method adopts mainly contains loosening blasting, leading bleeder off hole, deep hole control pressure relief blasting, the waterpower measures such as indent and hydraulic rupture, hydraulic loose, waterpower are extruded, hydraulic slotted liner technique of starting discharging along tunnel-surrounding, but these measures all have limitation.Mainly be applicable to weak projecting coal bed that ature of coal is hard, intensity of outburst is little as loosening blasting; The leading bleeder off hole engineering time is long, and the measure EFFECTIVE RANGE is short, imitates inspection exceeding standard rate height; Deep hole control pressure relief blasting is not solved owing to charge process at all; Hydraulic flushing in hole is a blowing phenomenon during at projecting coal bed boring, adopts the press water drilling hole, excites spray orifice to discharge outstanding energy, reduce the outburst danger in the certain limit, mainly is applicable to the cherry coal layering that stone door punching coal or blowing ability are strong.The limitation that these conventional methods exist is just brought certain restriction to speedy drivage work, has a strong impact on the operating efficiency of driving.
Summary of the invention
The utility model is at the limitation of tradition driving measure, provides a kind of widely applicable, little jet control coal of the high pressure that production efficiency is high and the outstanding device of gas.
Realize that the technical scheme that above-mentioned purpose adopts is: little jet control coal of a kind of high pressure and the outstanding device of gas, comprise giant and water under high pressure pipeline, also comprise hydraulic motor, walking car, high-pressure rubber pipe, hydraulic pressure Long-distance Control pumping plant and explosion-proof monitoring arrangement; Described giant is connected with the water under high pressure pipeline by high-pressure rubber pipe; Described hydraulic motor and giant are installed on the walking car, and the tooth bar engaged transmission of the gear of hydraulic motor output shaft end installation and giant gun barrel bottom; Described hydraulic motor is connected with hydraulic pressure Long-distance Control pumping plant by high-pressure oil pipe; Described explosion-proof monitoring arrangement comprises the explosion-proof camera that is fixedly mounted on walking car front end, and the explosion-proof display that is fixed in hydraulic pressure Long-distance Control pumping plant top.
Compared with prior art, this device possesses protection tunneling construction personnel's function, can also accelerate the driving face fltting speed simultaneously, and the tandem sequence of the face of rationally arranging work has reduced the input of gas control aspect, the effect of enhancing productivity.The coming into operation of this device can change the construction technology in the projecting coal bed excavation operation process, not only accelerated driving speed, and improved the safety factor of headwork.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Among the figure: hydraulic motor 1, giant 2, hydraulic giant support 3, walking car 4, high-pressure rubber pipe 5, high-pressure oil pipe 6, hydraulic pressure Long-distance Control pumping plant 7, water under high pressure pipeline 8, explosion-proof camera 9, explosion-proof display 10.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to accompanying drawing 1, in the present embodiment, little jet control coal of this high pressure and the outstanding device of gas comprise giant 2, by the water under high pressure pipeline 8 that high-pressure rubber pipe 5 is connected with giant 2, also comprise hydraulic motor 1, walking car 4, hydraulic pressure Long-distance Control pumping plant 7 and explosion-proof monitoring arrangement.Hydraulic motor 1 and giant 2 are installed on the walking car 4, the shell of hydraulic motor 1 is fixed on the upper surface of walking car 4, the gun barrel bottom of giant 2 is connected with two hydraulic giant supports 3, the lower end of this hydraulic giant support 3 is fixed on the walking car 4, and the tooth bar engaged transmission of gear that the output axle head of hydraulic motor 1 is installed and giant 2 gun barrels bottom realizes moving forward and backward of hydraulic motor 1 control giant 2 thus.Hydraulic motor 1 is connected with hydraulic pressure Long-distance Control pumping plant 7 by high-pressure oil pipe 6.Explosion-proof monitoring arrangement comprises the explosion-proof camera 9 that is fixedly mounted on walking car 4 front ends, and the explosion-proof display 10 that is fixed in hydraulic pressure Long-distance Control pumping plant 7 tops.Connect by circuit between explosion-proof camera 9 and the explosion-proof display 10, the driving in coal seam is monitored in real time, guarantee staff's safety.
Pressure limit in the giant 2 is 15-20MP.
The water under high pressure that water under high pressure pipeline 8 is carried arrives giant 2, relies on the jet of High Pressure Gun mouth to bore the coal cutting layer, forms also hole in the coal seam.Under the acting in conjunction of water under high pressure and mine pressure, coal body around the hole produces plasticity, creeping deformation, change stress in coal bed state, the extending stress band of coal body constantly moves to the depths, coal seam, unloading pressure zone enlarges gradually, gas permeability of coal seam increases, and gas pressure reduces, the release of coal body potential, the gas that the gas of adsorbed state is converted into free state is in a large number fully discharged, thereby has reduced coal and the outstanding danger of gas.Hydraulic motor 1 is controlled advancing of giant 2 by the engaged transmission of gear and tooth bar or is retreated, and hydraulic motor 1 relies on hydraulic pressure Long-distance Control pumping plant 7 to send the oil operation at a distance, in the process to the coal body cutting, personnel guarantee personnel's safety in remote-controlled operation.After finishing a circulation, gas bearing capacity and surrouding rock stress in the coal body reduce greatly, have eliminated gas outburst risk, and then carry out conventional driving, have accelerated the driving progress, have guaranteed personal security.
