To ensure industrial and mining safety the established safety rules for coal mines envisage the use of a number of complexes and systems, combined into multifunctional safety systems. These automated systems provide for people to be involved in the management of technological processes. The purpose of this paper is to assess how the coal mine safety requirements are aligned with other regulatory documents as they apply to modern safety systems in coal mines. To achieve this goal, the personnel location (positioning) and emergency alert systems in coal mine workings are analyzed for compliance with the requirements of the national standard for multifunctional safety systems in coal mines. It is shown that the current requirements for positioning systems are met by systems that have high accuracy in determining the location coordinates of people. It is suggested that positioning systems of the zonal type should be either upgraded to increase the number of readout devices to bring them up to the requirements of safety regulations in coal mines or replaced.

Mining in Colombia is regulated by the Mining Safety Code and although it had not been updated since 1987, the references of safety that has owned were based on international standards. However, these do not have a mandatory adoption and Decree 1886/15, despite its strong component in occupational safety and health, continues to show a rough technical content that could consent the extension of mining disasters associated with explosions in Colombia. The article specifies the international mine safety regulations and shows a critical analysis before the absence of its applicability in the country. Although the national outlook is discouraging because of the lack of rigor from governmental entities in enforcement, mining in other countries has reported improvements in safety by implementing standards that ensure quality operations and procedures, machinery and human resources, decreasing mining disasters.

Time and information are without doubt two key factors for successful coal mine emergency management. The advancement of information technology has brought new opportunities to improve coal mine safety. In this paper, a mobile coal mining safety monitoring system is introduced. The objective of the system is to help coal mine official acquire the real production environment data influencing mine safety in time anywhere and anytime thus be capable of responding to the matters arising immediately. The architecture of the system is proposed and it contains three layers including data acquisition layer, server application layer, and mobile client layer. Then, the system implementation details are elaborated. A use scenario is taken to demonstrate how the system can help safety official and relevant staff of the coal mine to respond to the changing mine production situation quickly and make time-critical decisions.

The radiated electromagnetic disturbances produced by operating electromotor equipments in coal mines have some effects on the electromagnetic environment in coal mines. Based on the analysis of the Chinese national EMC standard on rotating electrical machines and the operation characteristics of the electromotor equipments in coal mines, it can be concluded that frequency spectrum of the radiated disturbances resulting from AC motors ranges from 9kHz to 1GHz. The radiated electromagnetic disturbances in the pumping house underground mines have been measured. The results show that the radiated emissions above 30MHz produced by the normal running electromotor system are quite low, which are comparable to the radiated emission limits set in the Chinese national standard GB 755-2008;the maximum radiated field strength reaches about 0.56V/m under 30MHz. However, when motors start or stop, the radiated field strength can reach about 1.26V/m or higher. Therefore, some shielding measures for monitoring and communication equipments should be taken to reduce the radiation interference from AC motors.

Purpose The purpose of this paper is to devise novel methods for effectively reducing China’s coal mining accidents via analysis of the relation between coal mine safety production and social factors. Design/methodology/approach The variations and characteristics of the safety production for coal mines in China from 1949 to 2013 are studied via induction and statistical analysis of data from the perspective of mortality rate per million tons, raw coal output and death tolls. It is analyzed that the relationship between coal mine safety production level and social economic, safety investment via SPSS. Findings Analysis of the coal mine safety management evolution across the 64 years after the founding of China demonstrates that China’s coal mine safety management evolution is partitioned into four stages, and there is the coupling relation between coal mine safety production and structure the of coal industry, government supervision and safety investment. By discussing the similarity between China and America in coal mine safety management evolution, it is found that the rapid increase in the number of accidents during the transformation from agricultural to industrial society is not accidental. Practical implications The suggestions in this paper are helpful to improve the current safety situation in China’s coal mines and provide management experience to other coal mining countries. Originality/value Based on present and future socioeconomic development, it is proposed that the coal mine safety situation can be further enhanced by properly adjusting the structure of the coal industry, strengthening supervision and ensuring safety investment.

Safety problem has been one of the major issues in coal mining process. Therefore, a perfect mine safety monitoring system is necessary. It is one of the important aspects of a safety monitoring system how to acquire the exact position information real-timely of staff underground coal mines. To solve the problem of how to acquire of miners position, based on coal mine structure characteristics, with Zigbee technology, a kind of position system of underground coal mines is designed in the paper, and the efficiency of mine safety monitoring system can be improved greatly.
