法国1986年3月20日以来已采用井下输送带新标准。按照新要求,采用新材料、新工艺的输送带由法国煤炭科学研究中心代表法国煤管局作验收试验并签发下井许可证。关于输送带的耐燃性,新标准规定输送带每面电阻应小于300MΩ,作为抗静电要求。在大功率高容量输送机上采用金属骨架的输送带,小功率、输送带强度为800～1000N/mm的普通输送机宜使用单层织物骨架输送带(特点是经纱和纬纱密度很大,并浸透聚氯乙烯)。织物骨架输送带的张力安全系数取10左右,一般金属骨架的取7～8。输送带接头分热硫化、冷连接和机械扣3种,前者寿命最长。新标准按输送带强度划分的弹性伸
France March 20, 1986 has been the new standard downhole conveyor belt. In accordance with the new requirements, the use of new materials, new technology conveyor belt by the French coal science research center on behalf of the French Coal Authority for acceptance test and issue a permit to go down. Regarding the flame resistance of the conveyor belt, the new standard stipulates that the resistance of each side of the conveyor belt should be less than 300MΩ, as the antistatic requirement. In the high-power high-capacity conveyor with metal skeleton conveyor belt, low-power, conveyor belt strength of 800 ~ 1000N / mm ordinary conveyor should use single-layer fabric skeleton conveyor belt (characterized by warp and weft density, and saturated poly Vinyl chloride). Tensile safety factor of the fabric skeleton conveyor belt take about 10, the general metal skeleton to take 7 to 8. Conveyor belt joints heat curing, cold connection and mechanical buckle 3 kinds, the former longest life expectancy. The new standard by the strength of the conveyor belt elastic stretch
