Abstract: Given the complexity of emergency rescue for water hazard incidents in domestic coal mines, the paper analyzes the status quo of manufacture, usage and technology of submersible pump for emergence rescuing purpose, and discusses existing related problems. The trend of emergence rescuing submersible pump in China is then researched and demonstrated, as well as key technologies to be solved and tackled. Study shows that light-weight and mini emergency rescuing submersible pumps applicable to water hazardous environmental conditions, and supporting emergency drainage pipelines with high strength, light weight, fast joint, excellent compatibility and other features, are the inevitable trend in the future. In the meanwhile, that will improve emergency rescuing capacity for coal mine water hazard incidents constantly.
