Mine Shaft Sinking Technique and Technical Parameters of Mine Shaft Excavator

LIU Zhi-qiang;University of Science and Technology Beijing;National Engineering Lab of Mine Deep Shaft Construction;  
With an analysis on the conventional mine shaft sinking at home and abroad,mine shaft drilling method with mechanical rock breaking as the key and the drilling technical development of mine shaft excavator,mine shaft sinking technique of mine shaft excavator in China was provided. The mine shaft sinking technique would be a raise boring machine applied pilot shaft drilling,mine shaft excavator applied to ream the pilot shaft and breaking rocks to be run to mine roadway transportation with pilot shaft. With an analysis,special mine shaft headframe with drilling rods lifting function could realize up and down lifting of the mine shaft excavator. With the electric cables and the pipelines of ventilation and water,the electric power supply and water supply could be provided to the operation of mine shaft excavator and special multi function sinking stage could realize parallel operation of the rock breaking sinking and support. With an optimized design on the drilling head structure,the mine shaft headframe and the drilling rods could be applied to take the mine shaft excavator directly out of the mine shaft to solve the dissembling problems equipment in mine shaft. Meanwhile,according to the rolling cutter rock breaking of mine shaft excavator,based on the suitable strata condition,engineering condition and rational drilling speed,drilling pressure,rotary speed,power,support force and other parameters of the rock breaking were determined to provide references to the structure design of mine shaft excavator.
