1. Mineral resources
Mineral resources are naturally formed substances with a certain shape, certain physical properties and certain chemical composition. There are more than 3,000 minerals found in nature, and the most common ones are about 200. Up to now, 171 kinds of minerals have been discovered in China, and 153 kinds of minerals have been discovered, and 118 kinds have been developed and utilized.
2, ore
Mineral aggregates of useful constituents in the earth's crust, which can be exploited under modern technological and economic conditions, are called ores.
3. Ore body
Ore aggregate
4, the deposit
It is the general name of the ore body. It can be composed of one or several ore bodies. It contains two meanings, one is the geological environment in which the ore body exists, and the other is the quality and quantity of the ore.
The deposit can be further divided into:
1 Industrial deposits – Under current technical and economic conditions, mineral deposits that meet mining and utilization requirements are called industrial deposits.
2 Non-industrial deposits - in contrast to the above, called non-industrial deposits.
5, surrounding rock
The rock around the ore body is called a surrounding rock.
6, stone
The rock caught in the ore body is called a stone.
Physical and mechanical properties of ore
Hardness
Refers to the ability of ore (rock) stone to resist external mechanical action.
※ Hardness affects the choice of rock drilling equipment and crushing methods, as well as labor productivity, material consumption and mining costs.
2. Ruggedness
Refers to the performance of the ore (rock) stone against external forces.
※ The size of the ruggedness is usually expressed by the robustness factor f.
f = бC/ 100
※ Ruggedness affects rock drilling speed, explosive consumption and ground pressure management.
3. Stability
The size of the exposed area of ​​the ore (rock) stone in the space and
The performance of the length of exposure.
※ Stability and firmness are both connected and different.
※ According to the stability of the rock, the stability of the rock can be divided into five levels:
(1) Extremely unstable: When tunneling or mining, no exposed area is allowed, otherwise it may cause chipping or falling.
(2) Unstable: unsupported allowable exposed area within 50m2
(3) Medium stability: The allowable exposed area of ​​unsupported is 50-200 m2.
(4) Stable: The allowable exposed area of ​​unsupported is 200-800 m2.
(5) Extremely stable: The exposed area is not more than 800m2.
※The stability of ore rock affects the maintenance of the roadway, mining method and ground pressure management
The choice of method.
4. Agglomeration
Refers to the nature of the ore that is mined in contact with water and pressure, and rejoins into a block after a period of time.
※ The agglomeration of ore has an impact on the transportation of ore and the choice of mining methods.
5. Oxidation
It refers to the property of sulfide ore to become oxidized ore under the action of water and air.
※ Oxidation of ore will reduce the recovery rate of ore .
6. Self-ignitability
Refers to high-sulfur ore, which oxidizes in the air and releases heat. After a certain period of time, the temperature rises, causing the property of spontaneous combustion.
※ The spontaneous combustion of ore will increase the temperature in the underground and may cause underground fires. It has special requirements for mine ventilation, blasting methods and mining methods.
7. Water content
Refers to the performance of mineral rock absorption and retention.
※ The water content of the ore is difficult for mining, transportation, bucket lifting, storage and mining of mines, and roadway support.
8. Fragmentation
Refers to the nature of the volume increase after the rock is broken.
※ The ratio of the volume of the broken rock to its original rock volume is called the coefficient of expansion (or looseness coefficient).
※ The crushing property of ore rock has an impact on the transportation of rock and rock.
9. Border grade
The minimum content standard for the useful components of the ore body and surrounding rock (ore and waste rock). 10. Industrial grade – refers to the lowest average grade (also known as the lowest recoverable grade) of the ore body (mine section) that can be exploited under current technical and economic conditions, called industrial grade. The marginal grade and industrial grade of some ore
According to the nature of the minerals contained in the metal, and the chemical composition of the mineral component is divided into:
Natural metal ore: gold Au, natural sulfur S, graphite C, platinum Pt
Oxide ores: hematite Fe2O3, zinc ore red ZnO, soft manganese ore MnO2,
Red copper mine CuO, white lead ore PbCO3
Sulfide ore: chalcopyrite CuFeS2, sphalerite ZnS, pyrite FeS2, molybdenum ore MoS2
Mixed ore: Most metal ores are mixed ores.
Drilling Unit Processing Notes:
Work piece location:
Make decision of using half of work platform or the whole according to the size of processing work-pieces. Using the whole platform, the work-piece should be put on the processing position close to the clamping cylinder locating side, step two pedal switches, clamp the work-piece and start processing. Using half of work platform, the work-piece should be put on the front or back processing position close to the clamping cylinder locating side, step the corresponding pedal switch and start processing.
Rotating speed setting:
Rolling speed can be set according to diameter of dill and other relevant information. The speed of this machine has been set. There is no need for users to adjust. Users only need to input the diameter of drill bit and it will adjust suitable speed automatically.
Feeding speed setting:
Feeding speed can be set according to drilling manual or experiences. The speed of this machine has been set according to the diameter of drill bit. Users can adjust it flexibly according to the actual use. For specific adjustment method, please refer to computer programming instruction.
Self-running operation:
When all factors meet the condition which self-running need, the "Ready" indicator light on. Put "start" button, the machine will run automatically and process work-pieces meeting requirement.
Notice:
This machine has two platforms. When one is processing, the other can move to the frame head for mounting and dismounting. The clamping and loosing of work-pieces is controlled by pedal switch.
It will realize continuous processing, improve efficiency and save time.
