Abstract: In the tunnel and coal mine underground roadway construction processꎬ serious hydrogeological disasters are faced. Under the
complicated construction environment and hydrogeological conditionsꎬ it is very difficult to accurately predict water damage. As a widely
used electromagnetic induction exploration methodꎬ the mine transient electromagnetic method is mainly used to detect the water damage as
the water

bearing stratum which is low in electrical conductivity. And the mine transient electromagnetic method is sensitive to low resis ̄
tive bodies and is capable of detecting the aquifers in the tunnel and mine roof and floor. In order to solve the problem that the data pro ̄
cessing of roadway or tunnel transient electromagnetic detection is difficult and the accuracy is not highꎬ the two algorithms of particle
swarm optimization (PSO) and damped least squares (DLS) are compared and analyzedꎬ which solves the problems that PSO algorithm
has lower optimization efficiency in the later stage and DLS algorithm requires manual assignment of initial values. With reference to the
actual stratum dataꎬ the mathematical model was establishedꎬ and the inversion trial calculation was carried out by using PSOꎬ DLS and
the combined algorithm was proposed in this paper. The results showed that the combined algorithm had higher optimization efficiency and
did not need to manually give the initial modelꎬ comparing with the two separate algorithms. The combined algorithm was used to calculate
the measured transient electromagnetic data of the mine roadway in Huaibei Coalfieldꎬ China. The calculation resulted in anomalous sepa ̄
ration of the top and bottom plates. The interpretation results were consistent with the logging dataꎬ geological data and roadway exposure
conditions. It proves that the combined algorithm can invert the roadway transient electromagnetic detection data with high accuracy.
