The conveyor belt is the main tool of mine conveyor coal, due to the traditional rubber conveyor belt is flammable, can not meet the requirements of the underground flame retardant, so countries are not allowed to use under well. The whole fabric core conveyor belt easy antistatic and flame retardant, waterproof, moisture-proof, and has the advantages of light weight, anti tear, less energy consumption, so it is widely applied in the world of underground coal mine. At present in the world in some developed countries, in the use of coal mine 4000N/mm conveyor belt is almost PVC, PVG the whole fabric core conveyor belt, so the use of large amount of conveyor belt in the world, accounting for almost 1/3 of the amount of. The world the whole fabric core conveyor belt manufacturers mainly concentrated in the countries of the United Kingdom, Germany, France, Italy, Holland, Belgium, Canada, South Africa, Denmark, Switzerland, Japan and Chinese America, etc., of which the British and German production technology and product quality represents the advanced level in the world. In Germany the whole fabric core conveyor belt standards of DIN22109 (with fabric core conveyer belt in coal mine underground), they called this flame retardant conveyor belt for the self absorption band, and the past is difficult we call fire resistant conveyor belt of the DIN22103 standard is not allowed in germany. Britain is the world's most by producing the whole fabric core conveyor belt of the country, their implementation of the standard BS3289 (British the whole fabric core conveyor belt fire-retardant standard), is currently the world's most stringent standards. The world of the whole fabric core conveyor belt of the same provisions of physical and mechanical properties, but the provisions of the flame retardant performance tests differ considerably: America and Japan provides only alcohol burner combustion experiment, South Africa, Czech, Australia, India, Canada, provides only roller friction test experiment and burning alcohol burner, while Germany and EC law oxygen index test, roller friction test and roadway propane combustion test, the UK, Poland and China provisions do alcohol burner combustion experiment, roller friction test and roadway propane combustion test. At present in the safety performance of the countries in the world, the product can meet the national standard of the dog, but there are great differences in the mechanical properties. Some industrial developed countries can produce strength grade more than 4000N/mm, width of more than 3500mm of the whole fabric core conveyor belt, the service life of more than 10 years, can completely replace the steel wire rope core conveyer belt, and because the price, consumption, tearing, occupy the roadway space has advantages, so it is better than the steel wire rope core conveyer with more competitive.
