【摘要】 建设高产高效矿井必须首先要建设高产高效采煤工作面。然而 ,在影响工作面高产高效的诸多因素中 ,工作面系统的可靠性无疑是其中最关键的因素 ,只有提高工作面系统的可靠性 ,方能有效提高工时利用率和生产均衡率 ,进而达到高产高效之目标。结合潞安漳村煤矿 1 30 7工作面安全生产创水平前后的两次试验情况 ,就工作面系统可靠性对高产高效的影响进行了分析。更多还原

【Abstract】 This paper describes building high output and efficiency coal mine ,itmust build high output and efficiency workface at first.But there are a lot of reasons to influence high output and efficiency workface,reliability of workface system is a key reason,it can improve wovk time utilization ratio and product balance only in improving reliability of workface system,and achieve the goal of high output and efficiency.There are two test situations of saft product to procluce level in 1307 workface zhangcun coal mine of LuAn,and analyzes effect of high output and efficiency with reliability of workface system.更多还原
