Study and Practice on Early-warning and Control System of Catastrophic Airflow in Coalmine

摘要

Catastrophic airflow caused by mine fire and its secondary disaster threatens the safety production and workers of mines seriously. In Nantun coalmine, there are amounts of goafs, abandoned roadways, ventilation equipments, and these weaken the ability of disaster prevention and control. To solve this, warning and control system of catastrophic airflow in coal-mine is studied. This system consists of early-warning of catastrophe system, air door automatic control system, alarm system and remote control system. It improves the network, visualization, dynamic development of information processing software, and realized the automatic control of air door. This system ensures the safety mining effectively and improves the ability of disaster prevention and control.
