Roadways are various passages drilled between the earth's surface and the ore body for transporting ore, ventilation, drainage, pedestrians, and various necessary preparation works for newly digging ore for mining metallurgical equipment. These passages are collectively referred to as lanes.
Excavation is the task of excavating wells, roadways, chambers of various shapes, cross-sections, or criss-cross in rock or mineral formations. The tunneling process is divided into a main process and an auxiliary process. The main procedures are the procedures of ensuring the progress of the working face and the supporting operation in the roadway driving area directly completed on the working face. The main process is determined by the nature of the rock through which the roadway passes. When hard rock is tunneled, the main procedures comprise drilling, charging, blasting, ventilation, safety inspection of a working face, rock loading and roadway support; basic working procedures for tunneling soft rock comprise: digging, loading and supporting rock. If the method of adopting pneumatic pick, combination machine etc. is excavated, the excavation operation has the characteristics of continuous operation. The main steps may be performed in a strict sequence or simultaneously in time. The auxiliary process is a process for ensuring the normal operation of the main process and comprises shunting, ventilation, drainage, temporary support, working surface track laying, illumination, wind cylinder laying, cable laying and the like. In most cases it is performed simultaneously with the main process without taking up the tunnelling cycle time.
The roadway excavation refers to the work of excavating wells, roadways and chambers with various shapes, sections or criss-cross in a rock (soil) layer or a mineral layer;
the main working procedures of roadway excavation are the working procedure of directly completing the process of ensuring the progress of the working face on the working face and the supporting operation carried out in the roadway excavation area.
