Description

technical field

[0001] The invention relates to a continuous coal mining process method in an open-pit coal mine, and belongs to the technical field of coal mining equipment application and coal mining methods. Background technique

[0002] Most open-pit coal mines are near-horizontal deposits, with storage characteristics such as multiple coal seams, thick coal seams, and thick overburdens. Most of the coal seam burial angles are below 10°, and they belong to near-horizontal or gently inclined coal seams. At present, the most commonly used coal mining methods are: single Bucket shovel mining - truck transportation - self-moving crushing or centralized crusher crushing - semi-continuous or intermittent coal mining process conveyed by belt conveyor.

[0003] The above single-bucket electric shovel mining-truck transportation process has been widely used because of its flexibility and adaptability; however, compared with foreign advanced technologies, there are still disadvant...

Examples

Embodiment 1

[0061] All coal mining equipment, supporting equipment, tools and auxiliary materials are in ready working condition;

[0062] Prepare for coal mining according to the coal mining process;

[0063] Coal is mined by a continuous coal miner, and transferred to the unloading trolley by the walking crushing, bridge-type loader, and walk-type loader of the continuous conveying unit;

[0064] Use the unloading trolley to unload coal to the working face belt conveyor for coal transportation;

[0065] The belt conveyor in the working face transports coal to the belt conveyor in the Sinotrans level roadway;

[0066] The Sinotrans flat roadway belt conveyor transports coal to the Sinotrans machine roadway belt conveyor;

[0067] Coal is transported to the storage yard by the belt conveyor of the foreign transport machine for storage;

[0068] Coal conveying speed 2500-3200t / h;

[0069] Through the above process procedures, the whole process of coal mining-crushing-reloading-transpor...
