“…And the safety risk factors of hydrogen refueling station was classified into seven categories, such as the influence of station process layout, pressure-bearing equipment system, safety and security system, control system, human factors, environmental factors and regulations. The fire safety risks of hydrogen refueling stations was analyzed, and five primary indicators and 29 secondary indicators were established [10]. Then the primary indicators were summarized as building characteristics, fire protection facilities and equipment, building fire prevention, fire safety management and external rescue forces.…”

This paper divided the safety evaluation indexes of hydrogen energy industrial chain for transportation-energy integration in China into four target tiers, such as hydrogen production safety, storage & transmission safety, supply safety and hydrogen utilization safety. Then the influential factors of security risks under different target tiers were analyzed, and the evaluation index system of security risks were established. Furthermore, according to the characteristics of different target tiers of hydrogen energy industrial chain, the safety evaluation model was constructed by combining analytic hierarchy process with risk assessment matrix. This safety evaluation model can assess the safety status of hydrogen energy chain quantitatively and qualitatively, including calculating the weight of each index and analyzing the risk level of whole system. Moreover, such modeling method could provide a core assessment framework for enterprises and industries related to hydrogen energy to realize real-time security monitoring and alarm.

“…Fresh air is transported from the ground to different downhole locations during the production process, which provides breathing for workers and can dilute and eliminate all kinds of poisonous and harmful gases and mine dust. The establishment of a scientific and reasonable ventilation system is a basic guarantee for mine safety production, and is an economic way to improve the safe production level of a coalmine [1], [2], [3].…”

Catastrophic air current significantly influences the stability of ventilation system, and existing studies have not considered the flow characteristics of catastrophic air current when designing the control systems. To analyze the effects of different kinds of coalmine accidents on safety production, grey relation entropy theory was used to analyze the hazard assessment of coalmine accidents. Fluent software was employed to study the flow characteristics of catastrophic air current, and the catastrophic air current early-warning and control system of coalmine was researched according to the theoretical analysis and numerical simulation. The threat of fire accidents and roof accidents were larger than other accidents. The influence of temperature and CO volume fraction distribution of fire accidents to the tailwind side was larger than that of the weather side, and gradient decreased on the weather side. This system can effectively control the spread of fire and poisonous gas, and can judge the accident location immediately. The research effectively guaranteed the safety of mine production.

Using an analytic-synthetic model of ergonomic research of management information systems (MIS) in coal mines, we identified 13 elements which were used to define eight factors that impact operator's performance. These eight factors were further reduced to five key factors after the application of expert assessment. We have defined 23 indicators for these key factors, ranked by means of the analytic hierarchy process method. This paper includes a detailed ergonomic analysis of the five key operator quality indicators, namely, shape and size of the control panel, functionality of the video display terminal, keyboard functionality, alarm response time and expansion of the MIS with environmental parameters. Based on the condition prior to and after the proposed changes, we were able to use this approach to determine and discuss the operator quality index.Keywords: management information system; expert assessment; AHP method; operator quality index 1. Introduction The management information system (MIS) of an underground coal mine consists of the alarm and voice communication system, in addition to the configuration of the remote control system for ventilation, gas and fire parameters (concentration of methane, carbon monoxide, oxygen and smoke gases; speed and amount of air for circulating and separate ventilation; depression of the ventilation facility; temperature and air humidity, etc.), as well as data concerning excavating machinery, transport systems, extraction facilities, power supply and electricity distribution, mine drainage, etc. coupled with measuring devices and signal transmitters, devices for data collection and transfer, and devices for information displaying, printing and storing. This system is often adjusted for the specific nature of the underground mining technological process.Efficient control of the uneven and complex mining and production activities, followed by extensive data, is conducted by means of control and management centres (CMCs), which perform central monitoring and real-time decision-making and management, wherein the human operator is actively involved in the processes of notification, alert and management decision-making. In order to complete the MIS in underground coal mines, it is necessary to expand the system with information on the environmental impact of mining in the vicinity of the mine and to determine the qualitative and quantitative assessment of the impact. This is achievable by means of modern information
