摘要
本文为研究测定西山煤电东曲矿8号煤18408回采工作面顺槽的风阻特点,选择18408回采工作面上下2条顺槽作为风阻测定路线,通过数据的采集与汇总分析,回采工作面轨道顺槽阻力为1 084.2 Pa,运输顺槽的阻力为1 428.4 Pa,两段回采顺槽均属于高阻力区域,进一步分析数据可知18408回采工作面顺槽的有效风量率89.68%,符合相关规程规定。
In this paper, the wind resistance characteristics of the 18408 mining return face of Xishan Coal Power Dongqu Mine No.8 coal were measured, and two roadway under the 18408 return face were selected as wind resistance measurement routes, and further analysis of the data showed that the effective air flow rate was 89.68% in of the 18408 recovery face, in accordance with the relevant regulations.
