矿用自动风门的类型很多。据初步调查,目前我国冶金矿山已有十多种形式的自动风门。自动风门质量的优劣,直接关系到系统的有效风量,甚至影响系统本身的成败。评定一件产品质量的优劣,往往需要用一些具体的指标来衡量。目前我国冶金矿山还没有一个明确具体的指标来鉴定矿用自动风门。本文根据矿用自动风门在矿井运转的特定条件和1976年下垄钨矿樟斗坑口矿用自动风门鉴定预备会上大家提出的一些问题,对我国冶金矿山的矿用自动风门的质量指标
There are many types of mining automatic door. According to a preliminary investigation, at present, China’s metallurgical mines have more than ten kinds of automatic doors. The advantages and disadvantages of automatic throttle quality is directly related to the effective air volume of the system, and even affect the success or failure of the system itself. To assess the merits of a product quality, often need to use some specific indicators to measure. At present, China’s metallurgical mines still do not have a clear and specific indicators to identify mining automatic door. This article according to the mine automatic door in the mine operation of the specific conditions and in 1976 under the Long Tungsten mine camphor pit mine port automatic ventilation door identification of the preparatory meeting we raised some questions on China’s metallurgical mine automatic door quality indicators
