Abstract
The invention discloses a mine tunnel collapse alarm device which comprises an intelligent detection wire, a resistance detector and a computer, wherein the intelligent detection wire is connected with the resistance detector through a lead; the resistance detector is connected with the computer; wiring terminals are arranged on the lead between the intelligent detection wire and the resistance detector; and the intelligent detection wire is connected with the lead in a welding manner or through the wiring terminals. The mine tunnel collapse alarm device has a simple structure, is convenient to mount and high in detection sensitivity, and can be used for continuously and dynamically monitoring geological disasters, such as collapse in real time.
Description
Technical field
The present invention relates to tunnel, mine safety equipment technical field, relate in particular to a kind of mine tunnel landslide alarm.
Background technology
Landslide be tunnel, mine under natural force effect, appearance subside tenesmus natural phenomena.Roof fall is falling of digging space other job site balkstones of Nei Huo down-hole.In mine tunnel construction, landslide and roof fall are as broad as long sometimes, and the natural phenomena of the tenesmus of subsiding of the non-artificial appearance of this class is often linked together description.Landslide is the Serious geological disasters the most often occurring in mine tunnel construction, accounts for the more than 90% of all kinds of Serious geological disasters.For example, China Chengdu-Kunming Railway Line, Datong-Qinhuangdao Railway, the wide multiple line of weighing apparatus etc., the shut-down causing because caving in accounts for the 1/4-1/3 of total duration.Also once there is landslide in Hangzhou Subway tunnel and for example.Therefore, landslide is the geological disaster of maximum maximums of appearance in mine tunnel construction.The present geology monitoring and predictions such as landslide, be mainly to use the geologic prediction technology TGP quasi-instrument of having applied seismic wave forecasting technique (TSP) to measure geological type above, then by analyst, according to geological type, analyze the geological disaster that judgement may occur.The defect that this method exists is, needs analyst to have suitable rich experience and technology because same monitored data, because analyst is different, its predict the outcome also differ widely, its reliability also can vary with each individual; In general, prior art can only produce after sign in geological disaster, could to it, monitor, monitor and forecast, comparatively weak for the monitoring and prediction of geological disaster of not yet finding sign, thereby existing routine monitoring method to geological disaster cannot implement continuously at all, in real time, dynamically monitoring, can not meet automation requirement.
Summary of the invention
Object of the present invention is exactly in order to solve can only could monitoring it, monitor and forecast of prior art existence after geological disaster produces sign, comparatively weak for the monitoring and prediction of geological disaster of not yet finding sign, cannot implement continuously, in real time, the problem of dynamic monitoring; A kind of mine tunnel landslide alarm is provided; Simple in structure, easy for installation, detection sensitivity is high, to this class geological disaster of caving in can implement continuously, in real time, the mine tunnel landslide alarm of dynamic monitoring.
To achieve these goals, the present invention adopts following technical scheme:
Mine tunnel landslide alarm, comprises Intelligent Measurement silk, resistance detector, computer, and Intelligent Measurement silk is connected by wire with resistance detector, and resistance detector is connected with computer.
Described Intelligent Measurement silk adopts winter no matter or is all the titanium Ni based memory alloy silk of parent phase state summer, or copper-based memory alloy silk, or iron-based memory alloy wire is made.
Between described Intelligent Measurement silk and wire, by being welded to connect, or connect by prap.
Operating principle of the present invention: the present invention includes Intelligent Measurement silk, resistance detector, computer, Intelligent Measurement silk is connected by wire with resistance detector, and resistance detector is connected with computer.During monitoring, first Intelligent Measurement silk is fixed on to the inner surface of mine tunnel, again Intelligent Measurement silk and resistance detector is together in series and forms a closed circuit with prap and wire afterwards, and then the data that detect of resistance detector are inputted to computer.When mine tunnel does not still occur landslide and roof fall, the resistance readings being detected by resistance detector is zero; When landslide and roof fall sign appear in mine tunnel, the resistance readings that resistance detector detects is one and is greater than zero numerical value.If along with landslide and roof fall further aggravate, the resistance readings that resistance detector detects increases in linearity.Therefore, mine tunnel landslide alarm to mine tunnel collapse and cave-in can carry out continuously, real-time, dynamic monitoring.Specific works principle is: Intelligent Measurement silk is made by marmem, and its Af temperature is lower, no matter winter or be all parent phase state summer, shows super-elasticity.When there is landslide and roof fall sign in mine tunnel, the Intelligent Measurement silk of being made by marmem undergoes phase transition because being subject to the effect of collapse and cave-in displacement and pressure, by parent phase during to martensite transfor mation, its resistance can present linear increasing, and the speed that phase change resistor increases only depends on the speed of collapse and cave-in displacement, depend on the speed of collapse and cave-in.It is very fast that collapse and cave-in carries out, and the speed that phase change resistor increases is just very fast; It is very slow that collapse and cave-in carries out, and the speed that phase change resistor increases is just very slow.What no matter phase change resistor increased is fast and slow, and resistance detector all detects the variation of these resistance serially, and these resistance datas all can be inputted and be stored in computer.
Beneficial effect of the present invention: the present invention can realize to mine tunnel collapse and cave-in carry out continuously, in real time, dynamic monitoring, be widely used in colliery and mine, road and rail tunnel, subway tunnel, reduce the cave in loss of the pernicious burst accident of this class of mine tunnel.
Accompanying drawing explanation
Fig. 1 is the principle schematic of embodiment of the present invention.
Wherein, 1, Intelligent Measurement silk, 2, prap, 3, wire, 4, resistance detector, 5, computer.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention will be further described.
Mine tunnel landslide alarm, in conjunction with Fig. 1, comprises Intelligent Measurement silk 1, resistance detector 4, computer 5, and Intelligent Measurement silk 1 is connected by wire 3 with resistance detector 4, and resistance detector 4 is connected with computer 5.Described Intelligent Measurement silk 1 adopts winter no matter or is all the titanium Ni based memory alloy silk of parent phase state summer, or copper-based memory alloy silk, or iron-based memory alloy wire, titanium Ni based memory alloy silk are made.Between described Intelligent Measurement silk 1 and wire 3, by being welded to connect, or connect by prap 2.
Although above-mentioned, by reference to the accompanying drawings the specific embodiment of invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
