1、 What is the effect of improving equipment in mines?
Mine lifting equipment is the "throat" that connects the ground and underground. Its mission is to lift coal and gangue along the wellbore, lift personnel, materials, and equipment. It is one of the main electromechanical equipment in the mine production system.
2、 What are the components of improving equipment?
The coal mine lifting equipment consists of lifting containers (including cages, skip buckets, mining cars, and personnel cars), lifting wire ropes, pulleys, derricks, loading equipment, unloading equipment, and lifting machines (winches).
3、 How does the vertical well improvement system work?
The vertical well usually has a cage raised. One cage is located at the level of the bottom of the well and the other cage is located in the exit channel of the wellhead. The steel wire rope is connected to one end of the cage, and the other end is wrapped around the pulley and fixed on the drum. When the motor drives the hoist drum to rotate, the cage underground rises. Lower one end of the cage to allow it to move up and down along the channel in the wellbore for lifting operations.
4、 How is the lifting system for inclined shafts operated?
For the commonly used inclined shaft hoisting system, mining cars are used as hoisting containers. One end of the steel wire rope is connected to several mining car groups for hoisting, and the other end is wrapped around the pulley and fixed on the drum of the hoisting machine. The drum rotates to drive the hoisting car group to move back and forth in the wellbore for hoisting operations.
There are single hook and double hook methods for improving the quality of the vehicle. According to the different ways of parking, there are two types of parking lots: flat parking lots and flat parking lots. Single hook string car lifting can be used for multi-level lifting, usually using a swing car yard. Flat car yards are usually used for lifting double hook trains.
5、 What is the effect of the wellhead safety door?
To prevent personnel, mining trucks, and other items from falling underground, safety doors must be installed at the wellhead, bottom of the shaft, and the central transport roadway. Wellhead safety door and signal interlock: The safety door is not closed and cannot send a driving signal; After issuing the driving signal, the safety door cannot be opened; The safety door can only be opened after the cage is in place and a parking signal is issued.
