通过简要分析煤矿液压支架大流量技术改造的必要性及理论依据,并确定液压支架大流量技术合理方案及工艺的改造,以煤矿BC480-22/42型液压支架为例,最后对煤矿液压支架大流量改造前后控制进行对比。
Based on the brief analysis of the necessity and theoretical basis of technological reform of high flow rate in hydraulic support of coal mine and the rational scheme and technological modification of large flow rate of hydraulic support, the hydraulic support of BC480-22 / 42 coal mine is taken as an example. Traffic control before and after transformation contrast.
