Description

Technical Field

[0001] The present invention relates to the technical field of solid resource mining, and in particular to a solid resource mine continuous mining-loading-transportation integrated system and method. Background Art

[0002] The mining, loading and transportation operations of existing mining processes generally adopt a multi-link, segmented intermittent operation mode such as "electric shovel (or scraper) - dump truck (or chute) - semi-fixed / fixed crushing station - belt conveyor (or lifting container)". The mining, loading and transportation links are usually completed by independent equipment: mining and loading equipment (such as hydraulic excavators, electric shovels, etc.) is responsible for excavating ore from the mining site and loading it into transportation equipment; transportation equipment (such as dump trucks) transfers ore (or waste rock) materials to destinations such as crushing stations, spoil dumps or mineral processing plants.

[0003] The existing technology has the following defects:

[0004] 1. Discontinuous process and low efficiency: There are many operational links, and the collection and loading equipment and transportation equipment require frequent waiting and docking operations, resulting in operational interruptions (such as trucks queuing for loading and returning empty), which greatly reduces production efficiency. For example, the time utilization coefficient of dump trucks in a three-shift system is only 0.75;

[0005] 2. High costs (truck transportation costs account for 30%-50% of total mining costs): Mining and transportation equipment and dedicated transportation roads must be invested in simultaneously; equipment purchase, maintenance, and labor costs are high; trucks frequently make turns within the stope, resulting in extensive road maintenance and high safety pressures; and transportation distances in deep open pit mines increase dramatically with depth.

[0006] 3. Energy consumption and pollution: Dump trucks consume a lot of energy (fuel consumption can reach 50-100L per 100km), and they also cause serious pollution such as exhaust emissions, dust, and noise.

[0007] 4. Intelligent collaboration is difficult: There is a lack of real-time collaboration between individual devices, forming "information islands" and making it impossible to achieve a closed loop of production data.

[0008] Therefore, there is an urgent need for an integrated system and method for continuous mining, loading and transportation of solid resource mines to solve the above problems. Summary of the Invention

[0060] Cost reduction and energy saving: Eliminate the purchase and operation costs of dump trucks, reduce energy consumption by 40%-60%, and the energy consumption of belt transportation is only 1 / 3-1 / 2 of that of trucks;

[0061] Environmentally friendly and safe: no exhaust emissions, closed transportation reduces dust and noise, and avoids the risk of truck transportation accidents;

[0062] Save space: no need to build special ore and rock transportation roads;

[0063] Intelligent management: Achieve less-managed operations through intelligent control systems.

[0064] The present invention provides a continuous mining-loading-transportation integrated system and method for solid resource mines. The blast pile 4 is the ore rock after blasting in the mining field. At the blast pile 4, the mining-loading-transportation integrated system continuously transfers the ore rock from the blast pile 4 by the mining module 1 at the front end to the transfer module 2 extending from the lower part of the system. The ore rock is directly transported to the hopper 8 position at the rear end of the system through the transfer, and then directly transported to the ore yard, waste rock yard, chute and other destinations through the telescopic belt pulled by the rear end and the mine transportation main belt 5. There is no need for intermediate unloading and secondary loading. The control system dynamically adjusts the operating parameters of each module according to the ore flow to ensure operation continuity.
