3. Technical Implementation Case: Review of a Coal Mine Comprehensive Mechanization Reconstruction Project
Project BackgroundThe medium-sized coal mine previously used traditional stripping machines and diesel transport vehicles, which had issues such as low efficiency (daily handling capacity ≤ 500t), excessive dust emissions (dust concentration in the workplace ≥ 10mg/m³), and numerous safety hazards (brake failure accident rate of 0.5 times/month).
Technical SolutionMingshun Machinery offers a combined solution of "Sliding Excavator + New Energy Lithium Battery Electric Tricycle" and is equipped with an intelligent dispatching system.
(1) Mining process: Deploy 3 sliding scraper machines, operating协同作业 through wireless remote control, with individual efficiency increased to 100m³/h, achieving a daily transportation capacity of 2400t for the 3 machines.
(2) Transportation phase: Utilizing 10 new energy lithium electric three-wheeled vehicles, the driving range covers the entire transportation route underground. Charging stations are arranged at the intersections of tunnels, with charging time overlapping with loading time, achieving "zero downtime" operation.
(3) Smart Dispatching: Through real-time positioning with vehicle-mounted GPS and underground base stations, the system automatically assigns transportation tasks, reducing the empty-running rate of vehicles by 40%.
Implementation EffectivenessAfter 6 months of project operation, the daily shipment volume increased to 2200t, a 340% increase from before the transformation; the dust concentration in the operation area decreased to 1.5mg/m³, meeting national environmental protection standards; the accident rate of brake failure dropped to 0, significantly reducing safety risks; the comprehensive energy consumption of the equipment decreased by 18%, saving over 500,000 yuan annually.
Four, Summary of Technical Advantages: Innovation Logic Guided by User Needs
Mingshun Machinery's technical layout reflects three major characteristics:
(1)Scenario-based designSpecialized equipment is developed for different operational stages of the mine (mining, short-distance transportation, long-distance transportation) to avoid the issue of "poor adaptability of general-purpose equipment."
(2)Parameter refinementAll parameters, from motor power and hydraulic pressure to body dimensions, are optimized through simulation experiments and on-site tests to ensure "the technical specifications are highly matched with actual demands."
(3)Service闭环化Provide full-process services including equipment selection consultation, installation and debugging, operation training, and regular maintenance. Technical team response time ≤4h, ensuring stable equipment operation.
ConclusionMingshun Machinery has established a differentiated competitive edge in the mining machinery field through the "deep technical cultivation + scenario adaptation + service closed-loop" model. Its products not only meet the efficiency, safety, and environmental protection needs of domestic coal mines but are also exported to Southeast Asia, Africa, and other regions, with their technical adaptability recognized by the international market. In the future, the company will continue to invest in intelligent technology research and development, promoting the upgrade of mining machinery towards "unmanned and remote" directions, and providing more practical samples for the technological progress of the industry.
