《煤矿用织物整芯阻燃输送带》(MT 914-2008)标准颁布实施以来,对于促进煤矿安全生产、提高整芯带生产技术水平产生了巨大的推动作用。随着年产千万吨煤炭矿井陆续建成投产以及深井的开采,拉伸强度超过2000N/mm的煤矿用织物整芯阻燃输送带(以下简称整芯带)产品普遍被采用,输送机托辊倾角越来越大,对整芯带产品技术性能的要求明显提高,修订标准势在必行。笔者根据多年的生产和售后服务经验,提出几点改进意见。
Since the promulgation and implementation of the standard “Coal Mine Fabric Whole-core Fire-retardant Conveyor Belt” (MT 914-2008), it has greatly promoted the production safety of coal mines and the improvement of the production technology of whole core belts. With an annual output of 10 million tons of coal mines have been completed and put into operation and deep well extraction, tensile strength over 2000N / mm coal mine flame retardant conveyor belt (hereinafter referred to as the entire core) products are widely used conveyor roller Increasing inclination, the technical requirements of the entire core with a significant increase in product requirements, revision of the standard is imperative. The author based on years of production and after-sales service experience, put forward some suggestions for improvement.
