Zusammenfassung:The invention discloses a tunnel main hole and drainage hole blasting mutual interference rock mass parameter determination method, which comprises the following steps: detecting rock mass parameters in front of a tunnel face of a tunnel main hole or a drainage hole through blasting of the drainage hole or the tunnel main hole, and realizing advanced geological forecast by utilizing a propagation principle of seismic waves generated in a blasting process in rock mass. In other words, elastic waves are damaged when encountering unfavorable geology during propagation in the rock mass, the wave velocity is reduced, the vibration velocities at different positions are collected and compared, and therefore whether unfavorable geology exists in front of the tunnel face of the main tunnel or the drainage tunnel or not is speculated. The invention provides a tunnel advanced geology forecasting method which enables tunnel construction and geology forecasting to be carried out at the same time and does not affect the co
