Wireless sensor network (WSN) is more and more widely used in the mine because of its flexible configuration and strong adaptability. However, due to the special environment of the mine, WSN faces with a series of challenges. Through the investigation, it is found that the routing protocols used in the mine are mainly hierarchical routing. This paper firstly discusses the main idea of hierarchical routing protocol, and summarizes the main current issues; Then, regarding present problems, such as long data transmission latency, unbalanced energy consumption and short network life cycle, I discuss the advantages and disadvantages of different optimization algorithms for the hierarchical routing protocol in clustering mechanisms from the view of optimizing cluster head election method and controlling cluster range; Finally, I summarize the problems of wireless sensor network routing protocol used in mine and point out the future directions.
