输送带 地下采矿用纺织结构的橡胶或塑料覆盖输送带规范

[中文适用范围]： 本文件规定了用于地下矿井并布置在平或槽形托辊上的橡胶或塑料覆盖的纺织结构传送带的要求。它不适用于 ISO 21183-1 中所述的轻型传送带。本文件不包括塑料覆盖层的要求。这些要求由制造商和购买者商定，同时考虑到要使用的塑料类型。附件 A 中包含了不属于本文件要求但建议制造商和购买者商定的相关项目。附件 B 中给出了建议皮带购买者在询价时提供的详细信息。皮带的直线运行能力只有在安装后才能评估。因此，这方面的要求超出了本文件的讨论范围；不过，附件 C 中给出了横向偏移的建议。请注意使用皮带的地方可能存在的当地安全法规。 [外文原描述]： This document specifies requirements for rubber- or plastics-covered conveyor belting of textile construction for use in underground mines and disposed on flat or troughed idlers. It is not applicable to light conveyor belts as described in ISO 21183-1. This document does not include requirements for plastics covers. These are agreed upon by the manufacturer and purchaser, taking into account the type of plastics to be used. Related items that are not requirements of this document, but which it is recommended be agreed upon by the manufacturer and purchaser, are included in Annex A. Details recommended to be supplied by the purchaser of belting with an enquiry are given in Annex B. The ability of a belt to run straight cannot be assessed until the belt is installed. Requirements for this are, therefore, outside the scope of this document; nevertheless, recommendations for lateral drift are given in Annex C. Attention is drawn to local regulations for safety which might be in place where the belts are to be used.
