ZHJ Type Surface Grouting System for Mine Fire Preventing and Extinguishing

The ZHJ type fire preventing and extinguishing system was designed to meet the requirements of coal mine fire preventing and extinguishing and to improve the performance of the existing ground grouting system. Water supply system design and control and mechanical and electrical integration were emphatically introduced in the paper. Intelligent control was adopted in the system, so the procedure of fire extinguishing can be automatically carried on.
