Description
Technical field
The invention discloses a kind of preparation method of the mining injecting paste material of two-component, belong to reinforcement material technology of preparing neck
Domain.
Background technology
Coal and rock tunnel generally there are following safety problem in exploitation and tunneling process：1. seriously crushed in coal and rock
Location, roadway roof coal and part directly withstand on inbreak on full span length, and wall caving depth is big, and difficulty of construction is big, and safe condition is poor,
Easily cause accident；2. emit to fall behind at the top of tunnel and form cavity, accumulate a large amount of gas, bring many tired to ventilation and gas administration
, there is accident potential in difficulty；3. extremely hazardous in the empty in-cavity construction grillage hook top operation of inbreak, the grillage of local construction connects top effect
Difference does not connect top, and support is in instability status because of back timber sky branch, when meeting head on roof fall, easily causes support and smashes or push away and collapse.And it is right
Broken coal petrography is effectively treated, and common processing method one kind is increase support material, and another is exactly cement injection.Increase
Support material carrys out very big influence to the moving belt of coal mining support, and roof fall can not be fundamentally solved the problems, such as again；Cement mortar again because
The engineering properties such as its property noted difference influence, and do not reach grouting consolidation effect.
Chemical grouting technology is a kind of indispensable strengthening of foundation, impervious leakage-stopping, reparation concrete defect in modern project
Sunken advanced technology.It is by certain chemical material（Inorganic or organic material）The solution of low-viscosity is configured to, with chemistry filling
Stock pump（Single liquid pump or biliquid pump）, the force feed equipment such as simple stirrup pump poured into stratum or gap, with increase formation strength,
Reduce permeability, prevent stratum deformation and increase concrete density.Polyurethane injecting paste material is to be applied to water conservancy, water power, tunnel
Antiseepage, leak stopping, the important injecting paste material of reinforcement effect are played in the engineerings such as road, subway, mine, people's air defense, industry and civil buildings.It is logical
After engineer applied for many years and screening, the Polyurethane injecting paste material used at present in reinforcing for grouting in coal mine technology mainly has
Two major classes a, class is one pack system injecting paste material, is polymerized in advance containing certain free isocyanate groups base by polyethers and polyisocyanates
The performed polymer of group, then adds the constitutional chemistry slurries such as solvent, catalyst, surfactant, is by single liquid pump as needed
Slip casting can be carried out；Another kind of is two-component injecting paste material, and a component is the polyol based on polyethers, and another component is
Polyisocyanate compound, is mixed by bi-component grouting pump in construction part.
However, either any injecting paste material, it is higher all to there is viscosity, the problem of poor fluidity, is suitable only for crushing
Coal body working face is met head on local short distance（<5m）Injection slip casting, be not suitable for the long drilled holes slip casting in return airway and air intake lane, pin
Overall slip casting to large working area, its consolidation effect is restricted significantly, and existing injecting paste material exist it is inflammable, explosive potential
Danger, easily lights coal seam or other underground combustibles, forms underground fire.So, find new slip casting and reach reinforcing coal petrography tool
There is important Research Significance.
The content of the invention
Present invention mainly solves technical problem：It is higher for existing mining injecting paste material viscosity, poor fluidity lack
It is sunken that there is provided a kind of preparation method of the mining injecting paste material of two-component.
