【摘要】 通过对回采工作面支架工作阻力观测数据的分析表明,这些数据的分布规律并非完全为正态分布,因此目前采用的按正态分布法求取工作阻力的上限值是不完善的。作者在实践的基础上提出了应用百分位数法求取工作阻力上限值的具体步骤和计算过程,对矿压观测数据的处理有实际参考价值。更多还原

【Abstract】 Analysis of measured working resistance of coal face support shows that dis- tribution of the data is not completely a normal distribution.Therefore,to obtain the upper limit of working resistance of support by a normal distribution method is not a perfect method.The author proposes a percentage method based on practi- cal experience.The paper describes specific steps and calculation process which is helpful in processing observed data of rock pressure.更多还原
