Description
Technical field
The utility model relates to for the filling technique field such as goafs such as mines, particularly a kind of indicator that filling slurry stope height is carried out to accurate indication.
Background technology
Mine worked-out section is the underground vacant areas staying after mining, if do not carry out filling, can cause surface collapse, brings danger.Filling is carried out in goaf and can avoid land subsidence, eliminate unsafe factor.The material filling goafs such as sand, stone are used in filling exactly, form obturation roof supporting, country rock, prevent and reduce roof caving and distortion, alleviate the pressure of work plane.Conventional placement method has hydraulic fill, filling-up mechanically, filling-up pneumatically and consolidated fill etc. several.For preventing filling slurry spillage, or filling do not connect the phenomenon such as top and occurs, and goaf must be sealed or approximate sealing during filling.Therefore in filling, goaf filling situation cannot be in time, accurately grasp, and industry common practice is to calculate goaf volume; according to Filling Station instrument charging quantity, estimate underground filling situation; and in conjunction with personnel in the pit's micro-judgment, then feed back earth's surface Filling Station, determine shutdown opportunity.But this way is subject to interference from human factor; occur overcharging or charge less phenomenon; this is because filling slurry is after pipe-line transportation system enters down-hole; in sealing dead zone, affected by hydrated cementitious; dust granules vaporization is serious, and artificial naked eyes judgement difficulty is larger, often there will be error in judgement; and because of in vaporizer with hydrolysis product of cement, therefore larger to eye injury.This easily causes occurring overcharging or charge less phenomenon, and underground filling road is seriously polluted, and secondary cleaning work difficulty is large; Or it is low to cause filling to connect top rate, filling dead zone volume is not larger, and obturation cannot effectively be accepted overburden pressure, and easily stress concentrates accidents such as occurring rock burst, whole inbreak to occur.
In prior art, proposed some and filling has been carried out to the method for early warning.For example Chinese utility model patent CN102889097A discloses in underground filling, below the entrance 9-11 of down-hole feed bin rice, monitoring probe is set.Although goed deep into down-hole, and utilized monitoring probe, this is in fact also a kind of artificial vision, is also to utilize people to judge, not real-time judge, exists down-hole flue dust excessive equally, cannot see clearly, causes the accurate not problem of judgment mechanism.Therefore, how at underground filling, to set up automatic control system, grasp in real time underground filling situation, to reach accurate, reasonable shutdown, become the technical problem of needing solution badly.
Utility model content
The purpose of this utility model is to propose the accurate indicator of a kind of filling slurry stope height.Thereby make it possible to grasp accurately underground filling situation, and give warning in advance, look-ahead charging quantity, reaches the combination of early warning and charging quantity prediction, solves accurately, rational halting problem.

1, filling The Small Well and filling pipeline; 2, filling slurry; 3, safety power supply; 4, warning device; 5, wire; 6, controller; 7, float switch; 8, contact.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.Be understandable that, specific embodiment described herein is only for explaining the utility model, but not to restriction of the present utility model.It also should be noted that, for convenience of description, in accompanying drawing, only show the part relevant to the utility model but not entire infrastructure.
Embodiment 1:
Referring to Fig. 1 and Fig. 2, the accurate indicator of underground filling slip stope height comprises safety power supply 3, wire 5, warning device 4 and filling slurry charge level controller 6, wherein, described safety power supply 3 is given warning device 4 and 6 power supplies of filling slurry charge level controller by wire 5, filling slurry charge level controller 6 provides alarm signal to warning device 4 by wire 5, described filling slurry charge level controller 6, for airtight goaf filling height under accurate control well, comprise float switch 7, contact 8 and fixator.
While using this device, first select suitable position, controller 6 is fixed, after controller 6 being connected with wire 5, by filling The Small Well 1, wire 5 is caused to filling road, be connected with safety power supply 3 with warning device 4, during filling by safety power supply 3 switches manually to start key, while being fills up to permanent position, float switch 7 floats gradually under the effect of filling slurry 2, when float switch 7 touches contact 8, controller 6 sends the first alarm signal to warning device 4, warning device 4 automatic alarms, now staff will notify earth's surface Filling Station to shut down filling, now sand off.
In one is preferably implemented, safety power supply: be the power source of the accurate indicator of underground filling slip stope height, for whole system provides electric current.This device need be according to the Mining entrance continuous shift position that distributes, if adopt non-security voltage (being greater than 36V voltage), underground moving very flexible, and because of air humidity large, in route, the outstanding complex conditions that waits of crevice water limits, use non-security voltage easily because circuit question occurs short circuit, opens circuit, cause security incident generation etc.Therefore described safety power supply is less than 36V, and should follow and select the little large principle of not selecting.Preferably, safety power supply is 12V, can meet system power demand.
Wire: be down-hole control element, warning device and the Connection Element of determining good fortune power supply.Down-hole wire is subject to environment, power supply, limiting voltage, and in a preferred embodiment, wire adopts insulating properties good, the copper wires that resistance value is lower.
Described float switch can be float switch arbitrarily, it can be for example the rotation float switch rotating around fixator, and preferably, in controller 6, there is angular transducer (not shown) and can described in perception, rotate the angle that float switch rotates, when described rotation float switch turns an angle, for example 30 spend, can send second alarm signal relevant with rotational angle to warning device 4, the second alarm signal is different from the first alarm signal, warning device 4 will give the alarm, described the second alarm signal changes along with the variation of described rotational angle, therefore, warning device 4 is also through sending the alarm of variation, this variation can be the size of sound, kind, the variation of frequency, also can be the color of light, the variation of the frequency of flicker.For example, when rotating float switch 7, turn to while spending with respect to vertical direction angle 30, controller 6 sends the second alarm signal, warning device starts to send beeping sound, and along with rotational angle progressively increases, the second alarm signal changes along with the variation of angle, the frequency of beeping sound also increases gradually, with prompting staff slip, be about to fill, cause that staff notes, when rotation float switch 7 touches contact 8, controller sends the first alarm signal, warning device sends yowl, staff will notify earth's surface Filling Station to shut down filling, now sand off.
