巷道影响下全空间瞬变电磁场的分布规律及典型地质构造的响应特征

Since the acquire of coalfield system，geophysical technology and equipment has been introduced from the ground to mine, which TEM has been used widely。Mine transient electromagnetic field excitation and reception in the tunnel, in the process of transmission tunnel would affect it, not the whole theory of spatial distribution. Therefore, to ascertain the impact of roadway to improve the interpretation accuracy has an important role. In ways of theoretical analysis and numerical simulation, The article get the impact of roadway on the electromagnetic fields, and the response characteristics of typical geological structure by using numerical simulation.
