With the growth of production in mining, developing environmental protection consciousness, traditional mine environmental monitoring suffers from the delayed acquisition of data, single monitoring methodology and lack of sharing of information. This paper aims to develop a virtualized mine environmental monitoring system based on digital Internet of Things technology to increase efficiency. Environmental data in the mining area is first collected by deploying various sensors, after which the Internet of Things technologies continuously transmit data to the cloud for storage and processing. Data mining and analysis methods build up an environmental monitoring model and visualization technology to showcase the monitoring results. The system is able to provide real-time monitoring for the mine environment with data-transmission delays of less than one second and with an early warning accuracy greater than 95%. The virtualized mine environmental monitoring system effectively solves the problems embedded in traditional techniques and, thus, can be a reliable data supporter and a baseline for decision-making for mine environment management.
