This paper proposes an improved wireless communication channel reservation policy to address the impact on network performance cannot be analyzed under the original model with the primary and secondary users communication channel occupancy rates, and the problem that the secondary user blocking state is significantly higher than the primary user blocking probability under the original model. Simulation results show that improvement in network performance can be done by increasing the primary user communication channel occupy completion rate and the secondary user communication channel occupy completion rate. Also different users channel using request blocking probability can be reduced. It is more effective. That to improve the mixing network performance by improvement of secondary user communication channel occupy completion rate. The new improved model is important in ensuring the coal mine communication system (primary user) as the coal mine wireless communication system for emergency protection. Also the blocking probability of secondary users was reduced. The network access performance of the secondary user was enhanced and improved. The fairness among different users access to the hybrid network was ensured.
