摘要
在分析大倾角煤层飞矸运动形式的基础上,简化了工作面飞矸运动模型,推导出了计算飞矸运动特征的理论公式,在此基础上结合非概率区间分析方法,构建了飞矸运动的非概率区间分析模型,估计出飞矸运动速度、运动距离和动能的范围。通过算例,比较了区间分析方法与概率方法,结果表明不确定参数在小范围内变化时,区间分析方法能较好地估计飞矸运动速度、距离和动能的范围,验证了非概率区间分析方法在估计飞矸运动范围的可行性和优越性。
On the basis of analyzing the form of flying gangue movement in the steeply dipping seam,simplified the model of flying gangue movement and deduced the theoretical formula for calculating the characteristics of flying gangue movement. Then combined with the non-probabilistic interval analysis method, constructed the non-probabilistic interval analysis model of flying gangue movement and estimated the range of velocity, distance and kinetic energy of the flying gangue movement. Finally, a numerical example is given to compare the interval analysis method and probability method, the results showed that when uncertain parameters change in a small range, interval analysis method can better estimate the range of velocity, distance and kinetic energy of flying gangue movement and verified the feasibility and superiority of the non-probabilistic interval analysis method in estimating the range of flying gangue movement.
