Safety Features

According to the characteristics of the underground coal mine roadway structure and disaster environment, this article proposes an underground emergency rescue communication system based on wireless mesh network and its corresponding environmental monitoring subsystem. We design the structures of the emergency rescue communication system and the wireless mesh nodes. The nodes are designed with intrinsic safety features. The work also develops wireless multi-parameter environmental monitoring terminals, and sets up the software platform for the environmental monitoring subsystem. The developed underground coal mine emergency rescue communication system based on wireless mesh network and environmental monitoring subsystem are tested both on the ground and in a real underground roadway environment. Experimental results from the testing show that the signal strength is -45 dBm on average, and the bandwidth attenuation of each hop is less than 10%, the transmission delay after the 11th hop is only 14 ms. The developed emergency rescue communication system is functionally stable, the environmental monitoring subsystem is capable of performing real-time monitoring of various underground environmental parameters, and achieves high accuracy in monitoring.

Structure And Design

For the demand of coal mine flood accident emergency rescue, in this paper, a mine-used underwater explosion-proof robot is presented and the composition structure and design method of the robot are discussed in detail. This device combines mechanical design, underwater power plant, intelligent control, energy supply of mobile device and mine explosion-proof technology. It can cruise underwater with the changeable depth, orientation and speed. It can move flexibly and can collect underwater and overwater images. Practical application shows that this equipment is suitable for the emergency rescue and disaster relief work after the coal mine flood.

Abstract By decomposing the coal mine emergency rescue organization and coal mine emergency rescue work, the synergy entropy function is constructed by combining the synergy class with the entropy theory, and the synergy efficiency assessment model of coal mine emergency rescue is established. Analyze the synergistic relationship between departments in the rescue organization and between departments and functional units, construct the synergistic influence matrix, and obtain the synergistic status of the coal mine emergency rescue system by calculating the synergistic entropy, synergistic efficiency and synergistic degree. The quantitative analysis of the emergency rescue system in coal mines is achieved by analyzing the situation of the rescue work in coal mines and evaluating the rescue organizations at each tier based on the established evaluation model.

Based on the actual needs of the national mine emergency rescue base, WebGIS is introduced to the mine rescue and combined with the emergency rescue process to develop the coal mine emergency rescue management information system. This article introduces the systems compositions and relationships, identifies the needs and functional requirements of the system,designs the overall architecture of the system and each subsystem, and sets up the database according to the system functions. At present, the system has been applied to the emergency rescue base. The results indicate that the system can provide technical supports for the emergency rescue effectively.

Road safety system has been a concern topic for many scholars worldwide. Although there are many analysis papers on road traffic accident prevention, security, emergency rescue, safety evaluation and other aspects, there is no a thorough and complete opinion on road safety system. The study of these issues can cause a traffic accident prevention, to reduce the incidence of traffic accidents, summing up the spread of some of the impact of traffic on the control of the effective ways to combat the public security organs to reduce the incidence of traffic accidents guidance.

Hierarchy Process

Finding the shortest path is an important issue of coal mine emergency rescue. In this paper, based on Analytic Hierarchy Process theory, the roadway path weight is calculated, thus, influential factors weight on walking speed by roadway attribute is obtained. The establishment of the roadway equivalent length system constitutes roadway equivalent length adjacency matrix combined with path weight. Using adaptive ant colony algorithm and MATLAB software to simulate local roadway of a coal mine domestic, we get the shortest path in mine emergency rescue system, which is more reasonable and less time needed.
