【摘要】 针对掘进工作面瓦斯动态涌出的影响因素问题,重点分析了瓦斯动态涌出与掘进工艺的关系。统计分析了冀中能源股份有限公司东庞矿十二采区回风巷瓦斯浓度时间序列数据,编制Matlab程序,利用统计学分析方法,建立瓦斯动态涌出数据处理模型。结果表明,不同掘进工艺下,瓦斯涌出规律存在明显差异,其中打钻作业、掘进作业对工作面瓦斯浓度影响较大。更多还原

【Abstract】 Aiming at influencing factor problems about gas dynamic emission in heading face,the paper researches the relationship between gas dynamic emission and tunneling technology.It makes a matlab program,and builds a data processing model of gas dynamic emission by the statistic and analysis of gas concentration time series data in the return airway of Jizhong Energy Shares Company Dongpang Mine twelve mining area.The analysis results show that there are obvious differences in gas emission in different tunneling technologies,drilling operations and tunneling operations have a greater influence on working face gas concentration.更多还原
