Description
Technical field
The present invention relates to automatic monitoring field, particularly relate to a kind of goaf fireproof monitoring system.
Background technology
Goaf is by artificially to excavate or natural geological movement produces in " cavity " below earth's surface, and the existence in goaf makes the safety in production in mine face very large safety problem, and personnel and plant equipment all may be fallen into inside, goaf and come to harm.
Because Goaf Area has, latent property is strong, the regular difference of spatial distribution characteristic, goaf top plate caving collapse situation are difficult to the features such as prediction, therefore, how the distribution of Goaf Area, the inbreak situation etc. in spatial shape characteristic sum goaf are carried out to quantification and passed judgment on, be that puzzlement engineers and technicians carry out goaf potential hazard evaluation and rationally determine a key technology difficult problem for goaf punishment countermeasure always.
At present, underground vacant areas has become an important problem of restriction mine development, and along with mine is to deep mining, ground pressure increases, and underground vacant areas, in the pressure of powerful ground, easily cave-in accident occurs, and especially turns opencut impact to underground very large; Underground mining remains a large amount of stopes, chamber, tunnel do not process in time, brings serious hidden danger to strip mining transformation, brings serious threat to mine staff and equipment simultaneously.
Since 20 end of the centurys, China's mining activities order is comparatively chaotic, and illegally unordered unauthorized and excessive mining leaves a large amount of goafs in some mines and periphery thereof, and this is one of main harm source affecting current Mine Safety in Production.As Luanchuan In Henan molybdenum ore, Dachang, Guangxi mining area, Gansu factory dam Pb-Zn deposits, Tongling Shizishan copper mine, Lanping, yunnan Province Pb-Zn deposits, radio and television system ore deposit, all there is a large amount of goafs in many mines such as persimmon bamboo plantation ore deposit, Hunan, cause mining worsening condition, ore pillar is caused to be out of shape, adjacent operation area stope and roadway maintenance difficulty, down-hole large area inbreak, rock moves and surface subsidence etc., more seriously the casualties that causes of the high velocity air that collapses suddenly of dead zone and shock wave and damage of facilities, these all constitute a serious threat to Mine Safety in Production, and cause environment to worsen, mineral resources serious waste.The precondition solved the problem is exactly scientifically to detect immediate status and the spatial form of dead zone, down-hole, and administering safely for dead zone provides design considerations accurately with resource recovery.In conjunction with the Practical Project geological conditions of Luanchuan molybdenum ore, using underground space and goaf three-dimensional laser system (C-ALS) the part dead zone to mine detects, understand the shape of its dead zone, size and position, the software using it to carry carries out editor and becomes figure.Thus determine the particular location of dead zone on plot of a mine, the process for dead zone provides reliable theoretical foundation, thus guarantees the safety of operating worker and equipment.
To in process of coal mining, goaf brings harm usually to the normal production in colliery.Because in process of coal mining, goaf exists a large amount of float coal left over, the colliery spontaneous combustion that exists for of float coal provides goods and materials condition.Colliery spontaneous combustion serious threat the safety in production in colliery, is govern the production in colliery, and the spontaneous combustion of colliery, goaf occurs to occupy part and parcel totally in colliery spontaneous combustion.In China's State owned coal mine, the spontaneous combustion of colliery, goaf accounts for 60% of freely burning fire, and wherein most fire has leakage wind-induced.Have related data to show, heterogeneous goaf is divided into " three bands ", is salband, oxidized zone and suffocative zone respectively.Strengthen preventing to heterogeneous goaf the generation effectively controlling coal-mine fire.
In order to prevent oxidation of coal spontaneous combustion more than goaf, close the goaf is taked in ore deposit and to the measure such as nitrogen injection in goaf, slip casting, entering with starvation, prevents coal oxidation spontaneous combustion.In order to the flameproof effect of the various measures that inspection institute takes, need regular arrangement personnel observe the gas station in enclosing wall and check, observation content comprises the gas positive-negative pressure change etc. inside and outside the gas density of gas in goaf, carbonomonoxide concentration, temperature, enclosing wall.
There is following drawback in the mode of this artificial observation and inspection:
1, the fire prevention situation in goaf is observed, can be different because of the qualification of operating personnel, cause observed result there are differences.
2, the sense of responsibility because of worker is different, there is undetected situation.
If 3 enclosing wall bad sealings, high dense gas, carbon monoxide and other toxic and harmfuls may be had to overflow, and to observation, personnel bring danger.
4, measured real-time property is poor, is not easy judge goaf fire prevention situation in time and actively take treatment measures.
5, along with goaf quantity increases, need more artificial observation, increase ore deposit cost of production.
In addition, because the distributed pole in goaf is irregular, the workload of monitoring separately for each goaf is very large, and is unfavorable for unified management.
