Description
Technical field
The present invention relates to technical field of function materials, be specifically related to a kind of reinforcement material, a kind of mining high score
Sub-reinforcement material, filing provision and coal (rock) layer reinforcement means.
Background technology
As a big coal country, coal still will not change as the status of China's main energy sources, but China's coal-mine safety
Production form is fundamentally improved the most not yet, and annual mine safety accidents often occurs, and the mortality rate of coal mining accident is high.
The property safety of Safety of Coal Mine Production, the life security of protection miner and country is always in the weight of national security production protection it
Weight.Potential safety hazard in colliery has all many-sides, such as: gas, permeable, landslide etc..
New mine product material and technology are to eliminate the effective ways of the underground coal mine disasters such as gas, roof fall, fire and top board
One of, external new mine product Materials is with a long history, all has ripe use in the state such as Australian, Russian, German.With
That coal industry safety in production information and technology internationalization exchange increasingly extensively with go deep into, the ore deposit of Application comparison maturation abroad
Start incoming domestic with new material, the seventies in last century, Hebei Kai Luan group equipment Imported From German EMH Company product and technology, at Fan Ge village coal
Water blockoff has been carried out with macromolecular material under mine.Later, though this technology has been in progress in terms of scientific research, but there is no spread
And industrialization.Until 2000, Haoke Mining Engineering Appts. Co Ltd, Jining introduces and absorbs France's macromolecular material and technology,
The most progressively go on Independent Innovation.Through the development of more than ten years, new mine product material is as the elder generation solving Safety of Coal Mine Production
Enter technology, by domestic introduction, digest, absorb, the most mining macromolecule reinforcement material collapses and emits improvement and top solving work surface
In the safety problems such as plate is safeguarded, country rock solidification under reinforcing laneway and unfavorable geological condition, with its spy such as safe efficient and quick
Point obtains promotion and application widely.
Coal production proposes the higher target of renewal to safety management at present, and coal body reinforcing, gas control, water damage are prevented
The solution of model, roof control, fire extinguishing etc. safety engineering is increasing to the demand of safe new material, range of application
Increasingly wider, but now widely used mining macromolecule reinforcement material is buying, various in style, product technology and product matter
Measuring very different, be not easy to the integrated management of mine safety, the most current mining macromolecule reinforcement material is in use
It is primarily present following shortcoming:
(1) fractured coal and rock after reinforcing to stand repeatedly acutely mine pressure impact, to the volume contraction after material consolidation, glues
Knotting strength and comprcssive strength require the highest, but existing mining macromolecule reinforcement material is unable to reach this requirement of strength;
(2) the flash-point characteristic of existing mining macromolecule reinforcement material, flame-retarding characteristic cannot meet mine safety requirement;
(3) the rapid hardening characteristic of existing mining macromolecule reinforcement material cannot meet chemical consolidation and digging construction and quickly propels phase
