The invention relates to an electromagnetic type vibroseis parallel stimulation collecting and mixing record separating method. The method comprises the steps that focus points and an observing system are designed according to a common single focus collecting method, and the number n of vertical stacking times is determined through the experiment to serve as the number of focuses of parallel stimulation; n electromagnetic type vibroseises are arranged on the n focus points along a measuring line, the initial phase and stimulation delay encoding is carried out on scanning signals, the n focuses can be stimulated n times nearly at the same time, and n mixing records are obtained; the n focuses are integrally moved to the subsequent n focus points along the measuring line, and parallel stimulation continues to be carried out. Compared with an existing common single focus collecting method, if n focus parallel stimulation is utilized, a same number of focus points are collected, the work finishing time is 1 / n of the working finishing time of the common single focus collecting method, and in other words, the production efficiency is improved by n times. Production efficiency is greatly improved, effective signals in the obtained single focus records are clear, and waveforms are consistent. The vibroseis earthquake exploring working efficiency can be improved, and the construction cost of the field earthquake exploring is greatly reduced.
