| 摘 要： | 依据物理模拟相似性准则，采用物理模拟和井下试验方法，研究了煤矿井下巷道底板铁轨和金属架棚支护2种金属体的瞬变电磁响应特征.结果表明：巷道底板铁轨产生的电磁感应最强，金属架棚支护产生的电磁感应次之，巷道内只有锚杆金属体支护时产生的电磁感应最弱.建立了巷道内金属体影响校正的数学模型，提出了相应的校正方法和技术.实际应用结果表明:对巷道内金属体分布范围的数据进行校正，可避免假低阻异常体的解释结果.

| Abstract: | Based on the similarity criterion of physical simulation,studied the response characteristic of transient electromagnetic of two metallic facilities,rails and metallic shed supports in undergronnd coal mines.The results show that rails in laneway floor induce the strongest signal,metallic shed supports are stronger than bolting;built mathematical model of correction affected by metallic facilities in laneway,and proposed the correction method and technology.The practical application shows that the method of... |
