摘　　要：为了保证采煤工作面回采率符合相关规定,根据采煤工作面回采率计算方法,结合液压支架支护高度与工作面采高关系的分析,提出了利用工作面回采率校核液压支架高度的方法,从而为减少支架高度选择的盲目性、保证工作面回采率符合相关规定奠定了基础。In order to guarantee the working face recovery rate complying with relevant regulations, according to the mining face stoping rate calculation method, in combination with hydraulic support supporting height and the analysis of the working face mining height broken relationship, checking hydraulic support height method with working face recovery rate was put forward, which reduced the support selective blindness and ensured the working face recovery rate complying with relevant regulations.
