Description
Technical field
The present invention relates to technical field of mine safety, specifically a kind of gas exceeding limit early warning system and method.
Background technique
Gas Disaster is one of the disaster in Safety of Coal Mine Production.Wherein especially with coal and gas prominent and gas explosion
It is the most serious.Coal and gas prominent be underground coal mine coal seam with gas in a very short period of time, to digging space inside coal wall
The sufficiently complex dynamic phenomenon of a large amount of coals and gas is sprayed suddenly.It can in a short period of time, from coal and rock to tunnel or
Stope is dished out a large amount of coal petrography and gas, and generation such as pushes over mine car, destroys bracket, air flow in laneway is caused to reverse dynamic effect,
Underground facilities and equipment and ventilating system are often destroyed, and coal is be easy to cause to bury the wound such as personnel, gas asphyxiation, gas explosion
Accident is died, brings and seriously threatens to Safety of Coal Mine Production.Mine gas explosion is substantially in certain density methane and air
Oxygen interaction, generated under the action of certain temperature vigorous oxidation reaction.Once occurring, a large amount of people are not only resulted in
Member's injures and deaths, but also mine facility can be seriously destroyed, cause production disruption；It even can also cause coal-dust explosion, mine fire etc.
Second accident causes huge loss to aggravate disaster.In more than 11000 of China mine, 95% or more coal mine is used
Pit mining, high methane and coal and gas outburst mine account for 50% or more, and it is quick-fried that gas asphyxiation, gas easily occur for highly gassy mine
The mine safety accidents such as fried, coal and gas prominent, especially coal and gas prominent accident are big with destructiveness, complexity is high, can
The features such as foresight is low is major safety problems urgently to be resolved during current coal production.Therefore, study and grasp mine
It is particularly significant to ensure that the life security of miner has for mine safety production for gas accident occurrence cause and its Prevention Technique
Meaning.
By the gas accident mechanism study and field practice of decades, China forms a set of collection outburst hazard prediction
" quaternity " comprehensive outburst control measure technology body including forecast, outburst prevention measures, outburst prevention measures validity check, safety prevention measure
System.In addition, comprehensive analysis causes the temperature, oxygen concentration and gas density three of mine gas explosion according to study of Accident-Causing Theories
A primary condition obtains prevention and treatment mine gas explosion, should guard against underground coal mine methane accumulation first, avoids gas exceeding limit accident
Generation.Wind place gas density is respectively used by implementation " quaternity " comprehensive outburst control system and stringent control underground, it is effectively anti-
The generation of various Gas Disasters is controlled, but since the understanding to Gas Disaster mechanism is insufficient and the complexity of production scene, at present
Still it can not prevent the generation of Gas Disaster completely.
Coal mine safety monitoring system and outburst hazard prediction be prevent and treat mine gas, coal and gas prominent it is important
Technological means.Each operating location of mine is carried out currently, China's high methane, projecting mine rely primarily on coal mine safety monitoring system
Monitoring, the forecast of gas density, predict the outburst hazard of subterranean zone, for dangerous by way of drilling to coal seam
Region or working face take outburst prevention measures to eliminate outburst danger.But existing coal mine safety monitoring system, outburst hazard are pre-
Survey method still has insufficient and place to be improved: 1. between gas concentration monitoring forecast and outburst hazard prediction index
With opposite isolatism, comprehensive intelligent anticipation can not be carried out to face gas disaster；2. existing Gas Disaster monitoring system
System usually can not be to the real time job situation of subterranean zone or working face, such as ocurrence of coal seam, geological structure, ventilation, drilling gas
Situation of change carries out Real-time Feedback, is unfavorable for the real-time early warning of Gas Disaster；3. existing Gas Disaster prediction technique is most only
Consider that objective gas exceeding limit index, outburst hazard prediction index carry out Gas Disaster forecast, ignores and play a decisive role
The executive condition of mining management level and outburst prevention measures；4. existing Gas Disaster prediction technique is that simple utilize predicts to refer to mostly
Prediction result is provided to mark absoluteness, under the Gas Disaster grade and various warning grade cumulative functions that cannot still segment working face
First advance Gas Disaster occurrence tendency.
Currently, mainly there are German TF-200 gas monitoring system, Poland CMM- in foreign countries in terms of coal mine safety monitoring system
20 gas monitoring systems, U.S.'s SCADA gas monitoring system etc..The KJ90 safety of coal mines comprehensively monitoring system of domestic Chongqing Mei Ke institute
System, world science and technology joint-stock company Changzhou automate the KJ95 Coalmine's Monitoring and Controlling System of branch company, the KJF338 of Shenyang Mei Ke institute
Most of high watt in China of the systems such as mine safety production comprehensive monitoring system and the KJ4/KJ2000 of Beijing Rui Sai company
This, projecting mine is widely applied.Its software and hardware function, system stability and reliability etc. represent China's coal-mine
The technical level of monitoring and controlling system.Especially Mei Ke institute in Chongqing establishes digitlization on the basis of GIS-Geographic Information System (GIS)
Mine database establishes coal and gas prominent risk warning index, carries out trending early warning to coal and gas prominent and faces calamity
Early warning has established solid foundation for the further research of Gas Disaster early warning system.But in mine gas disaster alarm system
In terms of mine working face real time data typing in system, early warning and alert index interaction relationship, early warning system framework, still need into
One step research.

When section is less than design section 2/3, i.e. progress gas exceeding limit yellow early warning；In back production, driving face gas administration, when out
Existing gas, geological structure are not reported extremely or when the problems such as ventilation equipment artificial damages, i.e. progress gas exceeding limit yellow early warning；When
It was found that carrying out gas exceeding limit red early warning immediately when monitoring and controlling system stops transport or do not execute gas govenance.
Further include:
It realizes that the united multi objective of two or more pieces single index early warning is superimposed the early warning of gas exceeding limit comprehensive classification: only triggering one
A face gas is generated when index to transfinite yellow early warning, when meeting two or more pieces yellow warning index simultaneously, two
Item or a plurality of yellow early warning can upgrade to a gas exceeding limit red early warning.
The present invention makes full use of the information of the real-time gas density information and manual entry transferred to carry out early warning, in conjunction with newly opening
The downhole data input terminal of hair (assigns in coal seam the digging drilling depth of mine each department, the variation of gas index and face condition
Deposit, geological structure, ventilation, management factors) etc. the influence factor that may cause face gas and transfinite be managed and analyze, it is real
The real-time graded early warning of existing mine gas, coal mine gas, which is effectively reduced, to transfinite the probability of happening of accident, ensures the peace of mine
Full production.
