Underground Mining System With Separate Loading And Transporting Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing underground mining methods, such as the one disclosed in Patent Literature 1, face limitations in improving productivity due to the inefficiencies in ore transportation and excavation processes.
Innovation Solution
A mine mining system is introduced, comprising a transporting machine that loads and transports ore in a mine shaft while a loading machine excavates and conveys ore away from the mining area, with both machines operating independently to maximize their respective functions and improve efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a vehicle excavates and transports ore while holding the ore in the same machine, then the system is simpler, but the productivity is insufficient
Solution Approach 1:
The mining system is divided into separate functional units: a loading machine that excavates and conveys ore, and a transporting machine that transports ore in mine shafts. This segmentation allows each machine to specialize in its function, improving overall productivity despite increased system complexity.
Solution Approach 2:
Multiple mine shafts are combined to form a circuit configuration where transporting machines can operate continuously. The circuit connects multiple shafts to create an integrated transportation network that improves efficiency.
2Productivity
If a single mine shaft is used for both excavation and transportation, then the layout is simpler, but the mining amount per unit time is limited
Solution Approach 1:
The system transitions from using a single vertical shaft to utilizing multiple shafts arranged in a circuit configuration. This dimensional expansion allows parallel operations and increases the mining capacity while maintaining manageable complexity through standardized shaft designs.
3Productivity
If the transporting machine travels in one direction only, then the shaft design is simpler, but the transportation efficiency is reduced
Solution Approach 1:
The transporting machines operate dynamically in a circuit configuration, traveling in one direction around the loop and returning to the loading point. This dynamic circulation allows continuous operation and maximizes transportation efficiency while keeping the shaft structures relatively simple and standardized.

AI summary
A mine mining system mining ore from a vein in a mine including a mining area provided inside an ore body, a first mine shaft provided inside the ore body, and a second mine shaft connecting the mining area and the first mine shaft to each other, the mine mining system includes: a transporting machine which loads the ore mined in the mining area and transports the ore to a soil discharge area while traveling in the first mine shaft; and a loading machine which stays in the second mine shaft, excavates the ore in the mining area, conveys the excavated ore in a direction moving away from the mining area, and loads the ore on the transporting machine.
