基于瞬变电磁法的采空区探测研究

Study on Goaf Exploration Based on Transient Electromagnetic mMethod

本文针对泰安煤业开采对地质环境影响的问题,通过现场探查和应用瞬变电磁法对下部采空区进行了预测,进行了大回线源瞬变电磁测线18条,小回线瞬变电磁法剖面700 m,直流测深点6个。确定村庄四周的采空区范围,并推断采空区影响边界。村庄南部和北部基本未受采空区影响,东部受采空区影响较严重,并有一采空区进入村庄内部,为下一步环境治理及保护提供了坚实的基础。

Aiming at the influence of mining on geological environment in Tai’an Coal Industry Co.,Ltd.,the paper makes a prediction on the lower part of goaf through field survey and transient electromagnetic method and determines the goaf range around the village and the influential boundary,which can provide a foundation for further environmental control and protection.
