Description
Technical field
The present invention relates to mine safety field of engineering technology more particularly to a kind of research deep-wells to cause the effect of calamity source is lower to lose coal more
Ignition quality multifunction emulation experimental bench.
Background technique
The mine of deep mining gradually increases in China and the world at present, and deep mining is also coal mine Future Development
It is inevitable, it exploits popularization and Mechanization Level improves and accelerates the process that mine develops to deep again.Currently, China has had
Over one hundred a mine enters the deep mining stage, and the mine for entering deep mining in the future can be more and more.Mine fire is
One of the major casualty of Safety of Coal Mine Production is threatened, wherein again with mine self caused fire, i.e., based on spontaneous combustionof coal, in mine fire
90% the above are mine self caused fires.It is again maximum with goaf coal freely burning fire proportion in mine self caused fire, so
The main contents that goaf coal spontaneous combustion and prevention and treatment become research mine fire have in China's State owned coal mine according to statistics
There is the mine of spontaneous fire danger to account for about 51.3%.Deep Mine Coal Spontaneous Combustion Characteristics and superficial part have larger difference, in order to
Deep spontaneous combustionof coal is efficiently controlled, more thoroughgoing and painstaking research has been carried out to Deep Mine Coal Spontaneous Combustion Characteristics
It is extremely urgent.
With the increase of mining depth, the factor for influencing spontaneous combustion in goaf increases, and each factor is to spontaneous combustion of remaining coal
Influence degree, influence mode can be very different compared with superficial part.Such as: with the increase of mining depth, the stress of primary rock
Characteristic changes, coal seam gas-bearing capacity and pressure increased, rock stratum is increased by ground heat affecting temperature, mine resistance and
Air quantity increasing etc., these can all be such that deep spontaneous combustion of remaining coal characteristic will be different with superficial part.These influence factors simultaneously are such as high
Crustal stress, High-geotemperature etc. itself are exactly the cause calamity source of deep mining.If high-ground stress can cause stress high concentration, formed
Bump etc.；High-geotemperature can bring hot evil to mine, influence work task efficiency and health etc..Therefore, deep is opened
The characteristic for adopting spontaneous combustionof coal is to be caused the coupling of calamity source to be influenced by more.
Two methods are mainly used at present to the research of Coal Spontaneous Combustion Characteristics, i.e. numerical simulation and experiment is studied.It is testing
Mostly in research is that coal is placed in closed container, is then ventilated, loaded, heated to container, to coal in container
Oxidation temperature-rise period be monitored, gas in container ingredient be monitored, finally obtain coal spontaneous combustion period, oxidation
The parameters such as heating rate, oxygen consumption intensity, gas marker.These experimental provisions are mainly to carry out to the spontaneous combustion oxidation characteristic of coal
Research, and it is then helpless to coal research of spontaneous significance in goaf is lost.
The experimental study of spontaneous combustion in goaf characteristic when for deep mining, existing technology be primarily present it is following not
Foot: (1) current experimental provision mainly studies coal oxidation temperature-raising characteristic, and can get some relevant parameters, but cannot be right
Spontaneous combustion in goaf rule is studied, as the danger zone of spontaneous combustion in goaf and movement law, Residual coal in goaf from
Fire in temperature field and changing rule, goaf each field (temperature field, infiltration in the division of " three band of spontaneous combustion " and changing rule, goaf
Flow field, stress field, concentration field) Mutual Influence Law etc..(2) seldom consider in the experiment simulation process for carrying out spontaneous combustionof coal
Influence of the mine pressure to it, consideration is also only to load according to the characteristics of superficial part mine pressure to coal, is not accounted for
The characteristics of foundation deeps mines pressure is loaded, and (compared with superficial part mine pressure, not only pressure adds deeps mines pressure
Big problem).In addition when considering influence of the pressure to spontaneous combustionof coal, coal under different pressures during loading can only also be studied
The permeability and temperature-rise period of charcoal are the influence under a pressure, a kind of permeability to coal temperature-rise period at a certain moment, and
In practical recovery process, pressure, the permeability of goaf different location are different, and various permeabilities are to something lost coal temperature-rise period
Exist influence, different permeabilities again presence influences each other, i.e., be in goaf at a certain moment multiple pressure power, more permeabilities simultaneously
Influence oxidization of remained coal temperature-rise period.(3) existing imitative experimental appliance seldom considers influence of the gas to spontaneous combustionof coal, consideration
Also it is only to inject methane gas in experimental provision, studies influence of the gas bearing capacity to coal oxidation temperature-rise period, can not grind
Study carefully goaf gas to gush out and influence (goaf air leaking influence spontaneous combustion of remaining coal) of the gas pressure to goaf air leaking, goaf watt
The influence etc. of the influence, oxidization of remained coal heating of this flowing and concentration distribution to something lost coal temperature-rise period to gas migration rule.In addition,
There is also larger impact, voidage and goaf gas to the gas migration rule in goaf for the voidage of erecting dense individual props rock
The current experimental provision of relationship between body migration is also difficult to be studied.(4) environment temperature is not accounted for coal heating, mine
The influence of mountain pressure.(5) air supply of working face amount, the shadow for wind pressure to goaf air leaking amount, spontaneous combustion of remaining coal characteristic are not accounted for
Ring etc..
