Abstract:Mine disaster prevention is a prerequisite for ensuring safe production. In recent years, non-coal underground mines have increasingly focused on ventilation safety. However, due to the typically complex development systems of underground mines, unstable ventilation systems, and chaotic airflow, accidents involving toxic and harmful gas poisoning and suffocation occur frequently, posing a serious threat to mine safety. To achieve intelligent regulation of mine ventilation, the Kalatongke Mine has systematically conducted research on underground air demand calculation, 3D simulation of mine ventilation, and intelligent ventilation system framework planning. Based on the current production status of the mine, an intelligent monitoring and feedback control system for underground ventilation has been established, realizing the engineering application of intelligent ventilation technology. Research indicates that to meet the annual production demand of 1.5 million tons, the total required air volume for the mine is 240 m3/s. Through ventilation simulation, the necessity of installing air curtains in the mine"s ramp has been demonstrated, and it has been identified that the current main fans of the No. 2 and No. 4 shafts are insufficient to meet the mine"s air demand, leading to optimized selection of main fans. Based on the current underground ventilation system, 74 monitoring points have been set up. Through system architecture construction, network topology design, and business architecture design, the development of the mine"s intelligent ventilation system has been completed, achieving intelligent monitoring and regulation of underground ventilation and improving mine safety management. The relevant results can provide reference for the construction of intelligent ventilation systems in similar mines both domestically and internationally.
