Abstract: Aiming at the problems such as the detailed process simulation for roadway drivage is lacking,three-dimensional simulation is inadequate and decentralized data processing analysis,the overall framework of dynamic interactive simulation of the roadway drivage process with virtual reality technique is proposed,the key technical programs of static model making,dynamic simulation and human-computer interaction are analyzed in detail,and the dynamic interactive simulation platform of roadway drivage based on Unity 3D is developed.The function of dynamic simulation and human-computer interaction are realized of the rock drilling equipment and the roadway drivage process of drilling,charging and blasting,besides that,the data related roadway drivage can be collected effectively,and the construction parameters can be conducted statistical analysis,which is good to improve the teaching quality of blasting process of roadway drivage,strengthen mine safety training of staff and find the construction weaknesses.

Key words: Human-computer interaction, Dynamic simulation, Roadway drivage, Virtual reality, Unity3D
