A dynamic rescue route planning method based on 3D network in mine water inrush hazard

Abstract

Water inrush in mine is one of the most common hazards in the mining industry. To solve the problem of rescue route planning during a mine water inrush hazard, a dynamic rescue route planning method based on a 3 D network is proposed. First, the basic elements in the 3 D network model of the mine roadway are abstractly described, furthermore, the weights of edges, the topological connectivity of the elements, and the data structure of the network are defined. Then, the Dijkstra algorithm and the Breadth-first search algorithm are combined to implement the best rescue search route and return route planning based on the 3 D network model. Finally, the dynamic rescue route planning is simulated in 3 D virtual spatial scenario of a real mine. The factors such as topological connectivity of the elements, real-time water level, and slope of the mine roadways are considered in the process of rescue route planning, as the rescue route is adjusted dynamically according to the actual situations. This method proposed can provide powerful decision support for mine water inrush hazard rescue.

Study on emergency escape route planning under fire accidents in the Burtai coal mine

“…When a major disaster occurs in a mine, it can severely hurt underground workers and even threaten their lives 12 , 13 . Fire, vehicle collisions, and rockfalls are the most common emergencies in mineral and metal underground mines 14 , 15 . In most areas of a mine, fire can affect roof stability and produce toxic gases, thus causing hypoxic conditions and making spontaneous escape and rescue operations impossible 16 , 17 .…”

Modified Stochastic Petri Net-Based Modeling and Optimization of Emergency Rescue Processes during Coal Mine Accidents

“…Besides, life detectors, support vehicles of multifunctional rescue equipment, and detection robots have also been developed. The use of advanced equipment has greatly enhanced the ability of ER and improved the survival possibility of trapped miners [22][23][24].…”

Numerical assessment of the water-flow hazard to workers in the water disaster of underground mine

“…Evacuating workers to the surface safely and quickly is the ultimate goal in an emergency escape from water disasters in underground mines, and during such disasters, the existence of good escape routes is critical. Essentially, most current research focuses on finding escape routes ( Jalali & Noroozi 2009;Zhao et al 2019), mainly represented by the shortest-route model and its improvement model, which are based on the theory of the Dijkstra algorithm, Floyd algorithm, or the Ant algorithm. Although much has been achieved from these studies, there is a lack of consideration of the water-disaster environment, especially regarding the water flow in roadways and the worker's own situation.…”
