Abstract: Binocular distance measurement experiment was designed by the simplified structures and the simulated conditions in coal mine stope. The paper studied these differences between spatial perception distance and real distance in coal stope and its accuracy of safety level. Ten college students from Shandong University of Science and Technology were selected as experimental objects to locate the distances in the experiment. And it carried on classification and prediction for spatial perception distance safety level by using SVM. The experiment results showed that spatial perception distance was greater than real distance. The accuracy of predicting spatial perception safety level was 87.5% from far to near while the accuracy was 100% from near to far. The accuracy of predicting spatial perception safety level was high. The experimental results provided references for setting warning marks, mine locomotive position, track laying mines and other activities in coal mine.
