An Approach for Understanding and Promoting Coal Mine Safety by Exploring Coal Mine Risk Network

Table 1

Summary of previous study in coal mine.

Theme	References	Objective
Supervision and regulation	[13–18]	Exploring complexity and ineffectiveness of regulation; analyzing rent-seeking mechanism, behavior, policy, and tax; identifying tendency of coal mine accidents and characteristics of human factors.
Risk management	[19–24]	Predicting the expected risk levels by using decomposition technique in time series analysis; analyzing and optimizing the risk management system; using public communication system to monitor unsafe behavior in real time; reducing the effects of coal mining on social and ecological exploitation; constructing potential hazards database in an underground mine; evaluating the reliability of human safety barrier in coal mine emergency evacuation; identifying the risk factors and evaluating the safety control capability.
Risk evaluation	[25–31]	Assessing the roof fall risk during retreat mining in room and pillar coal mines; evaluating explosion risk in underground coal mines; developing a comprehensive model for coal mine safety; using fuzzy set theory to assess the risk of mining equipment failure; assessing pot-hole subsidence risk in coal mine; using risk performance indicators to analyze coal mine accidents.
Monitoring and controlling technologies	[32–36]	Employing internet of things (IOT) and cloud computing (CC) to monitor mine safety based on prealarm system; using wireless sensor network (WSN) to monitor the temperature, humidity, gas, and status of smoke in underground mine; establishing a Web of Things-based remote monitoring system for coal mine safety; employing cable monitoring system (CMS) and the WSN to build an integrated environment monitoring system for underground coal mine; using iris identification and radio frequency identification (RFID) technique to improve safety management system.
