摘要
本文以小常矿3402工作面为研究对象,介绍了该工作面的顶板概况,以此为基础分别对液压支架工作阻力、初撑力、支护强度和控顶距等进行了校验。结果表明ZF5600/17/35D型液压支架满足3402工作面支护要求。
This paper takes the 3402 working face of Xiaochang Coal Mine as the research object,introduces the general situation of the roof of the working face,based on which,the working resistance,initial support force,support strength and roof control distance of hydraulic support are verified.The results show that zf5600/17/35d hydraulic support can meet the support requirements of 3402 working face.
