| 摘 要： | 通过对48组煤矿掘进工作面瓦斯浓度监测数据的统计分析,发现瓦斯监测数据时间序列基本符合正态分布.利用数据分析软件,可以将瓦斯浓度数据是否符合正态分布作为瓦斯灾害的预警指标,并对瓦斯浓度异常特征值进行实例分析.该方法对预防瓦斯灾害具有重要意义. |
| 关 键 词： | 瓦斯预警 统计分析 正态分布 |

| Abstract: | Through the statistical analysis of gas concentration monitoring data of 48 groups of coal mine driving face,it is found that the time series of gas monitoring data basically accord with normal distribution.Using the data analysis software,whether the gas concentration data accords with the normal distribution can be used as the warning index of gas disaster,and the abnormal characteristic value of gas concentration can be analyzed by example.This method is of great significance for the prevention of gas disasters. |
| Keywords: | gas warning statistical analysis normal distribution |
