Advantages and disadvantages of the slope development method

Advantages: 1) Less affected by terrain, industrial site and other conditions;
2) The slope road has the functions of the main and auxiliary shafts, which is quick to develop and put into production early;
3) The mine production system is simple and has few links (ground → work point → operation point);
4) Comprehensive mechanization (trackless) for excavation, mining, loading, transportation and unloading, high efficiency and low cost;
5) Trackless maneuvering is flexible and easy to use.
6) Cancel the track and save a lot of steel.
7) The wellhead layout is greatly simplified without the need for lifting and corresponding ground structures.

Disadvantages: 1) Large amount of project development (3 to 6 times the amount of shaft engineering);
2) The depth of development is restricted by the technology and economic factors of the excavation;
3) The initial investment of trackless equipment is large, the maintenance workload is large, and the technical level is high;
4) If the trackless equipment is powered by diesel, the underground air pollution is serious. Use electricity for power.
