9. A method of directional blasting in mining area according to claim 8, wherein: the signal transmission time and the explosion time of the explosion test are recorded and kept in files for the explosion point after the explosion control chain is formed, time data are needed to be kept in files after each test, whether errors exist between the explosion time is compared and observed through multiple explosion tests, if errors exist, the range of the errors needs to be recorded, and then the time needed from the transmission of the simulated explosion command to the explosion is determined.
10. A method of directional blasting in mining area according to claim 1, wherein: when the blasting interval time is determined, the simulation time of the blasting control chain of the blasting point is compared with the simulation time of the blasting of the trace explosive, and the time difference of the simulation performed by the blasting data chain is equally converted into the actual blasting time, so that the blasting interval time of the blasting point is determined.
