Technical field
This utility model belongs to downhole safety early warning field, is specifically related to the anti-roof fall prior-warning device in a kind of colliery based on Laser Detection Technique.
Background technology
Colliery is as one of high risk industries, and along with increase and the change of lithology of mining depth, manifesting of mine pressure is more and more obvious, and the mode of roadway support and the rigidity of support material, flexibility, structure, difficult quality meet demand.For roof accident, it is different from gas and dust explosion, and the particularly serious serious accident of group dead group wound is the most rare, and scattered accident frequently occurs, the place that every people of having works, and is likely to occur this kind of accident, and distribution is the most extensive.Supervising general bureau's statistics, in November, 2015 according to national security, there are relatively major break down 4, dead 17 people in colliery, increases by 1,5 people on year-on-year basis；Coal-face roof accident accounts for the ratio of roof accident sum and has declined, but has still reached 66%, and roadway roof accidents then rises to 34%；Science and Technology Daily December in 2015 claims on the 27th, and Pingyi Gypsum Mine is caved in and caused the rock stratum roof fall of large area ore deposit, causes 1 people wrecked, the 17 stranded down-holes of people.
Owing to China's coal-mine exploitation also exists the dangerous present situations such as employee's working environment is poor, miner's safety consciousness is on the low side, enterprise security manager horizontal finite sum support apparatus is filled with flaws, thus cause accident of mine disaster to occur repeatedly, trace it to its cause, in underground top plate, mainly mining supports equipment occurs that leakage emits, crushes and can not effectively identify and pre-control time vibration is caved in.At present the fewest about the prior-warning device of the anti-roof fall in colliery, existing prior-warning device only can realize collection and the storage of data, but cannot realize fault diagnosis and the warning function of necessity, it is impossible to judge in time and pre-control is existing or contingent fault.Therefore, under Mine Complicated environment, need a kind of intelligent anti-roof fall safety early warning device of structure badly, effectively to identify and monitoring colliery roof fall accident.
Summary of the invention
The purpose of this utility model is to provide the anti-roof fall prior-warning device in a kind of colliery based on Laser Detection Technique, and leakage emits, crushes and vibration is caved in phenomenon to be used for preventing down-hole driving top board from occurring, it is achieved down-hole accident effectively identifies the purpose with safety pre-control.
In order to achieve the above object, the technical scheme that this utility model is used is:
The anti-roof fall prior-warning device in a kind of colliery based on Laser Detection Technique, including PLC master controller, described PLC master controller connects laser anti-risk backform block, fault detection module and warning module；Described laser anti-risk backform block includes that generating laser 1, backbone metal net 2, laser pickoff 3, every minute and second timer 4, leakage emit, crush and optical-electrical converter 5；Described fault detection module includes pressure transducer 6, vibrating sensor 7 and setting value；Described warning module includes liquid crystal display, phonetic alarm 8, flash alarm 9 and extension mouth.
Described generating laser 1 and laser pickoff 3 use many group side-by-side configuration to be installed on backbone metal net both sides, when laser pickoff does not receives the laser signal that generating laser sends, every minute and second timer starts timing, automatic clear when signal is replied, if timing is intermittent less than 10 seconds or signal, then occur that leakage emits phenomenon on the top board of mine working area, and can determine that leakage emits position according to installing numbering with phonetic alarm, if timing is more than 10 seconds and persistently timing, the laser signal disruption then caused for backbone metal net is bent by top board, and can determine, with phonetic alarm, position of crushing according to installing numbering；The thicker wire braiding that described backbone metal net 2 uses intensity harder forms, and mesh is 36cm2, and be supported on driving ground by some backbone metal bars 10, and press close to mine roof horizontal positioned；Described pressure transducer 6 is installed on backbone metal side off the net center position, for detecting the mine roof pressure to backbone metal net 2；Described vibrating sensor 7 is installed on mine roof 11 surface, for gathering the mine roof frequency of vibration produced because of probing, digging, and can pre-vibration proof cave in accident；Described liquid crystal display uses double large-size screen monitors 12864 liquid crystal display, mine roof 11 force value detected for display and frequency of vibration；Described phonetic alarm 8 and flash alarm 9 are installed on development end backbone metal bar 10, and when detected value reaches or exceeds setting value, phonetic alarm 8 and flash alarm 9 are simultaneously emitted by alarm signal.
This utility model having the beneficial effect that compared with prior art:
This utility model use PLC as master controller, the most competitively priced, programming is succinct, control accurately, but also can ensure that whole system stability under the complex work environment of down-hole and reliability；Rubble leakage emits or backbone metal net crushes cave-in accident to use the Laser Detection Technique of many group side-by-side configuration and every minute and second timer can effectively prevent development end top board to occur, it is achieved the purpose of identification of accidental events and pre-control；Use pressure transducer and vibrating sensor, can reach the purpose of multiple prevention and identification of accidental events；Use double large-size screen monitors 12864 liquid crystal display, the force value and frequency of vibration detected can be shown simultaneously, it is simple to ground handling operator grasps the Real-time and Dynamic of down-hole development end top board, shortening accident anticipation time in time.
This utility model designs the anti-roof fall prior-warning device in a kind of colliery based on Laser Detection Technique, PLC master controller used, Laser Detection Technique, pressure transducer and vibrating sensor belong to existing mature technology, reasonable utilization between this mature technology and combination, not only reduce the manufacture difficulty of this device, reduce the production capital and put into, and the new product after can making combination again has the good result that multiple early warning, identification of accidental events, control are stable, solid and reliable.
This device make simple, economical and practical, solid and reliable, control stable, in underground site is tested, can effectively prevent from tunneling top board and occur that leakage emits, crushes and vibration is caved in phenomenon, it is achieved down-hole accident effectively identifies the purpose with safety pre-control.
