Description
Technical field
The utility model relates to coal mine down-hole tunnel distortion warning device, is specially coal mine roadway deformation early warning system.
Background technology
Roof accident refers in underground coal mining process, crush and when two help to shift near deformation instability and reach threshold unexpected inbreak wall caving cause casualties, the accident of device damage and production termination etc.The 80s and 90s, roof accident accounts for the more than 40% of whole death tolls according to data, and the number that rises of roof accident accounts for total the more than 60% of number that rises.Though existing roof accident has minimizing, but still is one of major casualty of safety of coal mines.The important process that colliery guarantees safe production to top board implementing monitoring and early warning, current is mainly the on-the-spot data that use tape measuring or adopt roof separation indicator collection top board to change to the method for coal mine roadway deformation measurement, the data that obtain are that interruption is discontinuous, the system that neither one is real-time, comprehensive monitoring roadway shape changes.
Summary of the invention
The utility model cannot be in real time in order to solve the device of existing measurement coal mine roadway distortion, the problem of comprehensive monitoring roadway shape variation, and coal mine roadway deformation early warning system is provided.
The utility model is to adopt following technical scheme to realize: coal mine roadway deformation early warning system, comprise the mining laser range sensor that is fixed on tunnel one rib and back and be fixed on another rib of tunnel and roadway floor and reflection unit mining laser range sensor correspondence position, mining laser range sensor is connected by the dispatching platform of CAN bus and control alarm.
The mining laser range sensor being fixed on the rib of tunnel sends laser and the laser that the reflection unit on another rib of tunnel reflects detected, can measure the distance between two ribs of tunnel, while shifting near phenomenon when deforming in the certain area of the installation place of mining laser range sensor or reflection unit on the rib of tunnel, relative distance between mining laser range sensor and reflection unit or relative angle will change, and the distance of laser measurement will change; The mining laser range sensor being fixed on back sends laser and the laser that the reflection unit on roadway floor reflects detected, can measure the distance between back and base plate, while shifting near phenomenon when deforming in the certain area of the installation place of reflection unit on mining laser range sensor or roadway floor on back, relative distance between mining laser range sensor and reflection unit or relative angle will change, and the distance of laser measurement will change; Mining laser range sensor is connected with the dispatching platform of controlling alarm by CAN bus, the data that mining laser range sensor records can be transferred to dispatching platform, staff can grasp roadway deformation situation in good time, and compare and report to the police in good time by the alarming value adapting with mine condition, prevention mine roof accident is provided safeguard; This coal mine roadway deformation early warning system can be in real time, comprehensive monitoring roadway shape changes, once changing, roadway shape exceedes safety value, native system will and alarm, remind staff withdraw or carry out safeguard procedures, prevent as much as possible the generation of roof accident.
Above-mentioned coal mine roadway deformation early warning system, distance between mining laser range sensor on the rib of tunnel is 30～50m, distance between mining laser range sensor on back is 30～50m, and the variation at any place, tunnel can be monitored in real time by system like this.
Above-mentioned coal mine roadway deformation early warning system, reflection unit is speculum, simple and practical.
The utility model provides a kind of coal mine roadway deformation early warning system, this system can be in real time, comprehensive monitoring roadway shape changes, different collieries, different surrounding rock condition are all suitable for, need to before enforcement, analyze the residing roof condition of coal mine roadway, determine that different surrounding rock condition lower roof plate and two helps unstability threshold, to Safety of Coal Mine Production, reduce roof fall, side falling accident significant.
