Description
Technical field
The invention belongs to coal bed gas bioengineering field, and abandoned mine injection biomass is with losing coal cometabolism methane phase work
Skill.
Background technology
The China's coal-mine rate of extraction is relatively low, and particularly mining conditions difference or mining type select improperly mine, lose
Stay resource quantity huge, secondary recovery difficulty is big.Spontaneous combustion and Gas caused by coal are lost, not only waste of resource and pollution ring
Border, the safety in production to colliery cause serious threat, it has also become the main object that colliery is taken precautions against natural calamities.Biomass is primarily referred to as agriculture and forestry
The lignocellulosics such as stalk, trees in production process in addition to grain, fruit, farming industry leftover bits and pieces, agricultural are discarded
The materials such as fowl and animal excrement and discarded object during thing and Animal husbandry production.The utilization ways of biomass are more, but utilization rate is low,
Not only waste of resource, deteriorate ecological environment, such as the thing such as smog, flue dust and carbon monoxide caused by the burning of substantial amounts of agricultural stalk
Matter seriously endangers the health of people.Many researchs have confirmed that methanogen floras is widely present in abandoned mine water, in coal
Hydrogen content is relatively low, and biomass hydrogen content is higher, and coal combines the gas production that can significantly improve biological methane with biomass, exceedes
Single coal or biomass are as substrate aerogenesis sum.The present invention provides one kind in abandoned mine injection biomass with losing coal association
With metabolism methane phase technique, two kinds of resources being difficult by of something lost coal and biomass can be passed through methanogen floras in mine water
Metabolic conversion be clean energy resource-biological methane, realization is turned waste into wealth, and economic benefit and social benefit are notable.
The content of the invention
Present invention aims at offer one kind in abandoned mine injection biomass with losing coal cometabolism methane phase technique,
The biomass of something lost coal and injection in colliery is converted into clean energy resource-biological methane.
In order to realize purpose, the present invention adopts the following technical scheme that：Abandoned mine injects biomass with losing coal cometabolism
Methane phase technique, it is characterised in that：Comprise the following steps：
（1）Selection will scrap or written-off colliery, and degree of metamorphism is that middle low coal rank is optimal；
（2）Selection loses the more working face of coal or barrier pillar as testing site；
（3）Wall-rock crack and roadway engineering are handled, form a relatively independent closing space, meets to accommodate biomass
Ability, the basic demand that mine water can smoothly penetrate into, gas can be assembled；
（4）Two passages being connected with ground are established, one of passage is used for aerogenesis overflow channel, and another passage is used to give birth to
Material conveys；
（5）After Coal mine closure, biomass is passed through the closing space under default passage injection well；
（6）As the closed-in time extends, mine water is progressively completely soaked something lost coal and biomass, passes through aerogenesis overflow channel, prison
Control gas production rate, aerogenesis total amount and gas component；
（7）Contrasted with biomass or something lost coal as the aerogenesis total amount of single substrate, evaluation biomass is with losing the production of coal cometabolism
Methane effect.
Described step（2）The more working face or barrier pillar of coal is lost in middle selection, solid coal seam or does not have wherein
In the girdle for having extraction value is also included within.
Described step（3）As long as middle treatment measures satisfaction accommodates the ability of biomass, mine water can smoothly penetrate into, gas
The basic demand that body can be assembled；As long as solid coal seam can reach in above-mentioned requirements are also included within.
Described step（4）Middle to establish two passages being connected with ground, one of them is used for aerogenesis overflow channel, another
The individual biomass that is used for conveys.
Described step（5）Biomass is injected into testing site by middle realization.
Described step（7）It is middle biomass-something lost coal mix gas production can exceed single creature matter gas production with it is single
Coal gas production sum is lost as evaluation criterion, the index that evaluation criterion includes has gas production rate, aerogenesis total amount and gas component.
Using microorganism species present in mine water, coal is converted into together with biomass the gas based on methane, only
Meet that this category feature belongs to the protection domain of this patent.
Using above-mentioned technical proposal, the present invention has great originality, utilizes the production being widely present in abandoned mine water
Methane flora, promote biomass and lose coal cometabolism generation methane, improve and lose coal utilization rate and biomass gas generating amount, realize
Turn waste into wealth, the purposes of energy-saving and emission-reduction.
Embodiment
Technique of the abandoned mine injection biomass of the present invention with losing coal cometabolism methane phase, includes following step successively
Suddenly：（1）The colliery that will be scrapped is selected, degree of metamorphism is lignite；（2）Selection loses the more barrier pillar of coal as testing site；（3）
Slip casting is carried out to wall-rock crack, enclosing tunnel engineering, testing site is met that receiving stalk, mine water smoothly penetrate into, produced
The gas such as methane the basic demand such as can assemble；（4）Two passages being connected with ground are established, one of them overflows for aerogenesis
Go out passage, another is conveyed for biomass；（5）After Coal mine closure, biomass by presetting the examination under passage injection well
Test a little；（6）60 more than d are waited, pass through aerogenesis overflow channel, monitoring gas production rate, aerogenesis total amount and gas component；（7）In phase
The aerogenesis that single lignite and stalk are carried out respectively with the conditions of as substrate is tested, and can biomass-something lost coal mixing aerogenesis be surpassed
Above-mentioned aerogenesis sum is crossed as evaluation criterion, evaluation biomass and the cometabolism methane phase technique for losing coal.
Described step（2）The more working face or barrier pillar of coal is lost in middle selection, solid coal seam or does not have wherein
In the girdle for having extraction value is also included within.
Described step（3）As long as middle treatment measures satisfaction accommodates the ability of biomass, mine water can smoothly penetrate into, gas
Body such as can assemble at the basic demand.As long as solid coal seam can reach in above-mentioned requirements are also included within.
Described step（4）Middle to establish two passages being connected with ground, one of them is used for aerogenesis overflow channel, another
The individual biomass that is used for conveys.
Described step（5）Biomass is injected into testing site by middle realization.
Described step（7）It is middle biomass-something lost coal mix gas production can exceed single creature matter gas production with it is single
Coal gas production sum is lost as evaluation criterion, including the index such as gas production rate, aerogenesis total amount and gas component.
The present invention can make full use of existing equipment and condition in abandoned mine, and biomass is carried out into biology turn with losing coal
Change, improve methane yield, eliminate the environmental problem that crop straw burning is brought, improve the utilization rate for losing coal.
