采煤工作面液压支柱的强度和质量关系到采煤生产的安全性。本文对双仲缩支柱的稳定性强度进行了理论计算,并对样柱进行了验算和实验测试。测试结果表明该产品质量未达到厂商所作出的技术保证。
The strength and quality of hydraulic props in coalface are related to the safety of coal production. In this paper, the theoretical calculation of the stability of double-supported struts has been carried out, and the sample column has been checked and tested. Test results show that the quality of the product does not meet the manufacturer’s technical assurance.
