【摘要】：為了準(zhǔn)確監(jiān)測煤礦井下突水水源水質(zhì)的變化,消除溫度對pH值的影響,在傳統(tǒng)pH值監(jiān)測煤礦突水水源的基礎(chǔ)上,提出了基于PSOR迭代算法的pH值溫度補償模型,為煤礦突水預(yù)警提供了新依據(jù)。該方法采用了曲線擬合的方法對幾種常見煤礦突水水源建立了E-pH值模型,且進(jìn)行了相關(guān)數(shù)據(jù)處理,最終應(yīng)用于奧灰水、1煤層頂板砂巖水、9煤層頂板砂巖水的pH值監(jiān)測。試驗結(jié)果表明:在3種水樣溫度分別為5、15、25、35、45℃五種情況下時,傳統(tǒng)方法水樣pH值誤差最大,為0.85,有溫度補償水樣pH值最大差值僅為0.13。該方法的應(yīng)用有效克服了傳統(tǒng)溫度測量存在誤差較大的缺點,通過PSOR法對pH值進(jìn)行溫度補償,能夠?qū)崿F(xiàn)對溶液pH值的精確測量。
[Abstract]:In order to accurately monitor the change of water quality and eliminate the influence of temperature on pH value, a temperature compensation model of pH value based on PSOR iterative algorithm is proposed on the basis of traditional pH monitoring of water inrush source in coal mine. It provides a new basis for early warning of water inrush in coal mines. This method adopts curve fitting method to establish E-pH value model for several common coal mine water inrush water sources, and carries on the correlation data processing, and finally applies to the monitoring of the pH value of the roof sandstone water of the roof sandstone of Ordovician 1 coal seam. The results show that when the temperature of three kinds of water samples is 5 ~ 15 ~ 25 ~ 35 ~ 45 鈩，
