The conveyer belt is the main tool for transporting coal underground. As the traditional rubber stratified belt is combustible, it can not meet the flame retardant requirements of the underground, therefore, China has banned its use in the underground. At present, the conveyor belt used in coal mine is flame retardant and antistatic conveyor belt. This conveyor belt has two main categories: fabric whole core flame retardant conveyor belt; Wire rope core flame retardant conveyor belt. They can not only meet the needs of coal transportation, but also have excellent safety performance, so they are widely used in coal mines, and become the absolute main force of coal underground transportation.
The advantages of fabric whole core flame retardant conveyor belt: flame retardant, antistatic, waterproof, moisture-proof, tear resistant, thin belt body, small quality, less energy consumption, production process is relatively simple. Its disadvantages: large elongation, short service life (generally not more than 4 years), the cumulative coal capacity is not more than 5 million t.
The advantages of wire rope core flame retardant belt: flame retardant, antistatic, high tensile strength, good impact resistance, small elongation, good slotting, good bending resistance, long service life (generally in 5-8 years). Its disadvantages: thick belt body, large mass, tear resistance, transportation process of high energy consumption, complex production technology.
At present, the whole fabric core flame retardant band grade is low, tensile strength is generally not more than 1600N/mm; Wire rope core flame retardant band grade is higher, tensile strength is greater than 1400N/mm.
