摘要
通过对工作面突出前夕瓦斯涌出浓度时间序列(简称G序列)的分析,提出了利用股市技术分析方法进行突出预报,以山西晋城寺河煤矿"5.20"突出事故监测数据为基础,绘制了工作面G序列K线图。研究表明:正常生产时期,K线实体很小,为小K线或十字线,近似一条平稳水平线;突出前夕,G序列K线整体上呈上扬趋势,阳阴实体明显变大,K线上升过程中多次出现"三阳线"(中阳或大阳线)连拉,表现为一种脉冲信号。根据K线上述变化特征可实现突出预报。
By studying the time series of gas emission concentration before coal and gas outburst, the stock market the- ory was proposed to forecast coal and gas outburst. Based on the data of "5 · 20"coal and gas outburst of Sihe Coal Mine in Jincheng, the K line charts for time series of gas emission concentration, named as G series in short, were drawn. The results indicate that the K line is acted as little K line or cross line with little variance at normal production periods. Before outburst, the K line has an ascending trend, its bodies become large, and "three-positive line" fre- quently appears, which exhibits pulse signals. The research results can be selected as the precursors to forecast coal and gas outburst.
