Demand Analysis and Scheme Design of Coal Mine Safety Monitoring System

In this work, a safe Coal Mine Monitoring system which replaces the traditional coal mine monitoring systems which tend to be wired network systems. This play an important role in coal mine safe production. With continuous enlarging of exploiting areas and extension of depth in coal mine, many laneways become monitoring blind areas, where are lots of hidden dangers. Moreover, it is inconvenient to lay cables which are expensive and consume time. In order to solve the problems, we designed a coal mine safety monitoring system based on wireless sensor network, which can improve the level of monitoring production safety and reduce accident in the coal mine. Zigbee technology provides a direction for scientists who commit to solve the safety monitoring problems of coal mine. The purpose of this study is to propose a solution suitable to mine wireless communication, safety monitoring, give a proof to the further study.

A wireless coal mine safety monitoring system based on ZigBee wireless sensor network and GPRS wireless remote transmission was established, which enjoys the characteristics of ZigBee technology, including quick networking, low cost, less power consumption, simple network structure and real-time parameter monitoring. With mature GPRS technology, remote data transmission was achieved and associated director can be informed through short message sent to his cellphone, which contributes to the early identification of serious accidents and real-time treatment, thus increasing the safety of coal mining.

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.
