The method comprises the steps of confirming and selecting a basalt removal construction mode according to the interference thickness between models, determining whether the basalt is completely removed or partially removed according to the basalt thickness, adopting an integral removal mode if a rock stratum is smaller than or equal to a threshold value, namely, the rock stratum is thin, and removing the basalt of the interference part if the rock stratum is larger than the threshold value, namely, the rock stratum is thick, without completely removing the basalt. The threshold value can be confirmed according to actual conditions, and is not limited in this embodiment.
