用高精度磁测圈定煤田自燃区的应用效果
摘要
煤田自燃在中国北方非常普遍
每年都给中国的煤炭资源以及生态环境造成重大损失。为控制和监测煤田自燃
须对其自燃边界进行圈定。煤层自燃后产生“热剩磁”
基于这一理论
运用高精度磁测圈定了西北某煤田自燃区的边界范围
并建立了“倾斜磁化有限延伸的板状体”模型进行正演。由钻孔验证的结果来看
高精度磁测圈定煤田自燃区边界范围的应用效果良好。
Abstract
Self-combustion is very common in coal-fields of northern China
which takes great losses of coal resources and impairs the ecological environment in China every year.The border of self-combustion zone should be determined in order to control and monitor the self-combustion of coal-field.The coal layers would be magnetized after self-combustion.Based on this theory
we have determined the border of coal combustion with high-precision magnetic measurement in a coalfield in northwest of China.The equipment used is IGS-2/MP-4
with parameters being totally magnetic-ΔT.To determine the border precisely we propose a model of "finite plate-shaped body of inclined magnetization".The exposure of drill holes show that the border of self-combustion can be reasonably determined by high-precision magnetic measurement.
