降低机械化支架的金属用量是煤矿机械制造的重要问题之一。机械化支架的重量占综采设备重量的90％。 虽然科研单位和工厂在降低机械化支架金属用量方面作了大量的工作,但并未解决这个问题。 例如,2MK(2MKЭ)型综采设备批量生产已超过十年,尽管所采用的轧制板材的强度几乎提高0.5倍,但支架的金属用量只降低16％。
Reducing the amount of metal used in mechanized stents is one of the important issues in the manufacture of coal mine machinery. The weight of the mechanized scaffolds accounts for 90% of the weight of the fully mechanized mining equipment. Although research institutes and factories have done a great deal of work in reducing the amount of metal used in mechanized stents, this problem has not been solved. For example, the 2MK (2MKЭ) fully mechanized mining equipment has been mass-produced for more than a decade, and although the strength of rolled plates used has been increased by almost a factor of 0.5, the metal content of the support has been reduced by only 16%.
