提出了用股市K线图法分析大气压力变化的新方法,K线图分析方法的优点是不但能反映出大气压力的总体变化趋势,而且能反映出单个周期内大气压力的变化,并且不会产生因数据取样采点而可能引起的误判问题。以唐山矿地面监测站的大气压力监测数据为基础,绘制了大气压力变化K线图。对比分析了大气压力变化及开采因素对唐山矿T1493工作面瓦斯涌出的影响,结果表明:瓦斯涌出速度与大气压力下降速度基本呈正比关系,而与大气压力下降的具体值关系不大;大气压力变化对瓦斯涌出的影响小于开采因素带来的影响。
A new method to analyze the atmospheric pressure change with stock market K-line graph method is proposed. The advantage of the K-line graph analysis method is not only reflecting the general trend of atmospheric pressure but also reflecting the change of atmospheric pressure in a single cycle, Resulting in sampling errors due to data sampling problems that may arise. Based on the atmospheric pressure monitoring data of Tangshan Mine Surface Monitoring Station, the K-line graph of atmospheric pressure was plotted. The results show that the gas emission rate is in direct proportion to the descending speed of atmospheric pressure and has little to do with the specific value of atmospheric pressure drop. The impact of atmospheric pressure on gas emission is less than the impact of mining factors.
