Arrangement of equipment wells without sublevel caving

If the equipment well is arranged in the surrounding rock of the upper plate, although it is beneficial to improve the recovery rate of the ore, in order to avoid the safety of the roadway due to the movement of the surrounding rock, the tunneling amount is increased. Therefore, the equipment well is placed in the surrounding rock of the upper plate only when the surrounding rock is not stable and the rock on the upper plate is stable and the inclination of the ore body is large.

Shaft Section Equipment - The size of the apparatus may be transported, such as iron ore temple device Shaft Section 2.8 * 2.8 m ² (Driving Section).

The use of equipment wells - the degree of mechanization of the bottomless column method, in order to facilitate the transportation of equipment, materials, personnel to each section is convenient, it is necessary to dig equipment wells. In addition, the equipment well is generally used as the inlet well (the Damei Iron Mine 24#, 26# ore body each open a equipment well, the 24# ore body length is 200~~300 meters, and the 26# direction is 100-320 meters long. )

Equipment in the equipment well - there are currently two types of equipment, one is to use the same center of the equipment well, install two sets of lifting equipment, transport personnel and small materials, use the elevator car. When transporting large equipment, the steel rope of the elevator car is placed on one side, and the car is parked at the level of the last section, and is lifted by a slow-moving winch. This type of excavation is small and the number of workers is small. Another form is to install equipment wells and elevators, equipment wells to install high-power winches, transport the body equipment, and then dig an elevator shaft to specifically upgrade personnel and materials. This type of arrangement can be used in large mines where the transport equipment is busy.
