模拟单一介质火区试验研究及数据分析

Experimental study simulating single medium fire area and the data analysis

目前国内外有关自燃火区覆盖岩层介质极化率、介质电阻率与温度三者关系研究较少.本文通过室内的多参数试验台,使用直流电法仪在各测点上进行多个AB/2值的视极化率和视电阻率数据的采集,同步采集相应三维空间点的温度值.通过整理、分析、归纳和对比试验数据揭示热源上单一介质覆岩的各参数之间的关系.由于深度、视极化率、视电阻率与温度之间复杂的非线性关系,最后本文以某点为研究对象,利用BP神经网络对该问题进行探讨研究.

There are less research on the relationships between medium polarizability, medium resistivity and temperature in rock above spontaneous combustion fire area at home and abroad now. The paper collected the polarization and the apparent resistivity datas by useing the DC Act Instrument in every measuring point on different AB / 2 values, and collected corresponding three-dimensional space-point＇s temperature values through the interior multi-parameter test bed. It reveals the relationships between each parameter in a single medium on the heat based on the compilation, analysis, summary and comparison of these data. The relationships between depth, parallactic polarizability, parallactie resistivity and temperature is non-linear. Taking one point for example the paper studies this question using the BP neural network.
