通过研究矿井直流电法探测结果,提出了基于贝叶斯估计的直流电法探测结果可靠性评价。为了合理地考虑评价过程中各种信息,使用了混合Beta先验分布,并根据历史样本确定了先验分布参数和继承因子,然后利用后验分布分析了直流电法探测结果的可靠性。最后,结合平煤股份五矿采区实际情况,分析了不同采区使用直流电法探测后效果,结果表明,该方法可以作为煤矿企业实施直流电法探测技术依据,提高水害防治的成本投资效益。
By studying the detection results of the mine direct current method, the reliability evaluation of the detection results of DC method based on Bayesian estimation is proposed. In order to reasonably consider the various information in the evaluation process, the mixed Beta prior distribution is used, and the prior distribution parameters and succession factors are determined according to the historical samples. Then the reliability of the DC detection method is analyzed by posterior distribution. Finally, according to the actual situation of the Minmetals Mining Area in Pingdingshan, the effect of DC mining method in different mining areas is analyzed. The results show that this method can be used as the basis of coal mine detection technology to improve the investment benefit of water damage prevention and control.
