Research and Application of Intelligent Explosives Filling System for Drilling-and-Blasting Tunnels
The construction technology of drilling and blasting method is developing rapidly.The key processes such as tunnel excavation drilling,initial support and secondary lining have realized mechanized and intelligent construction to a certain extent,while the explosive loading process is still dominated by manual work.In the excavation process,the use of rock drill jumbo for drilling operations is becoming more and more extensive.It is necessary and practical to develop an intelligent explosive filling system in combination with rock drill jumbo.Combined with the characteristics of emulsion explosives and the status quo of charging equipment,the charging work units are scattered on the drilling trolley and the charging trolley.At the same time,the drilling control,charging control and blasting optimization software are developed,which are used for drilling process,charging process and blasting optimization process respectively,so as to realize the integrated construction and cycle optimization of drilling and blasting.The system has been successfully applied in the Xiaofeng Tunnel of Yixing connecting line.
