One, Enterprise Technology Layout: Full-chain capabilities from R&D to implementation

Shandong Mingshun Machinery Manufacturing Co., Ltd. relies on a 21,000-square-meter factory area and an 18,000-square-meter workshop storage to build a technical closed loop integrating R&D, production, and sales. Its technical team absorbs advanced achievements from home and abroad, forming two major technical sections centered around mining equipment and transportation equipment, covering the entire process from underground operations to surface transportation. For example, its sliding scraper uses high-strength wear-resistant steel material, with the whole machine weighing 8.5 tons, suitable for mine environments with slopes ≤25°, and improves the scraping efficiency by 30% compared to traditional equipment; while the 1.5T-20T overhead line electric locomotive supports flexible adaptation of voltage levels from 250V to 550V through modular design, meeting the power supply conditions of different mines.

Part Two: Technical Analysis of Mining Equipment: High-Efficiency Operation Solutions under Complex Conditions

1. Sliding scraper: A tool for operations in narrow spaces
The equipment is equipped with a 37kW three-phase asynchronous motor, featuring a 600mm diameter挖掘斗, with a single digging capacity of up to 0.8m³. Its core advantage lies in the sliding steering technology, with a minimum turning radius of only 3.2 meters, allowing for flexible maneuvering in tunnels with a width of ≥3.5 meters. In a coal mine in Shanxi, the equipment operated continuously for 12 hours without any faults, with an average daily stripping volume exceeding 1200 tons, a 5-fold increase in efficiency compared to manual labor.

2. Crawler scraper with large gradient: Stability assurance for steep slope operations.
For mines with an inclination greater than 25°, Mingshun Machinery has developed a crawler undercarriage structure. By increasing the crawler ground contact length to 2.8 meters, the ground pressure ratio is reduced to 0.12MPa, effectively preventing slippage. Its hydraulic system uses a dual-pump merging technology, with a digging force of up to 150kN, capable of easily breaking rocks with a hardness of ≤f8. In the application at a lead-zinc mine in Yunnan, the equipment operated continuously on a 35° slope for 6 months, with a 98% equipment integrity rate.

III. Technological Breakthrough in Transportation Equipment: Solutions for Long-Distance High-Efficiency Transportation

1. Overhead traveling trolley: An economical choice for heavy-duty transportation
Mingshun Machinery's 20T trolley-mounted electric locomotive adopts IGBT variable-frequency control technology, boasting a traction force of 120kN and a maximum operating speed of 12km/h. Its energy recovery system feeds braking energy back into the grid, achieving a real-time energy-saving rate of 25%. In a mining transportation line in Inner Mongolia, the equipment covers a single trip distance of 3.2 kilometers, with an average daily transportation volume exceeding 5,000 tons, reducing the energy consumption cost per ton-kilometer by 40% compared to diesel vehicles.

2. New Energy Lithium Battery Electric Tricycle: Micro Transportation Innovation for Green Mines
In response to the short-distance underground transportation needs, Ming Shun Machinery introduces an electric tricycle equipped with a 48V/200Ah iron phosphate lithium battery, offering a range of 80 kilometers with a charging time of only 2 hours. Its explosion-proof motor has passed the MT/T 661-2011 standard certification and can safely operate in environments with gas concentration ≤0.5%. In a pilot project at a gold mine in Guizhou, the equipment replaced traditional diesel tricycles, significantly improving the underground air quality, with a 60% decrease in PM2.5 concentration.

4. Technical Adaptation Scenarios: From Single Device to Systematic Solution

Mingshun Machinery's technical layout is not only reflected in the performance of individual machines but also emphasizes the collaborative adaptation between equipment. For example, its underground small sliding loader can be combined with a milling excavator to form a "excavation-loading"联动 system, achieving seamless connection of work processes through wireless remote control and reducing manual intervention. In a renovation project at a certain iron mine in Sichuan, this system reduced the number of workers from 8 to 3 per working face, saving over 2 million yuan in annual labor costs.

Five, Technical FAQ: Key Considerations for Mine Equipment Selection

Q1: How to choose a scraper suitable for the slope of the mine?
A: A comprehensive assessment of slope angle, tunnel width, and rock hardness is required. For instance, when the slope angle ≤ 25° and tunnel width ≥ 3.5 meters, the sliding scraper is to be prioritized; when the slope angle > 25° or rock hardness > f6, crawler-based equipment should be used.

Q2: What are the differences in application scenarios between electric vehicles and battery-powered vehicles?
A: Track-mounted electric locomotives are suitable for long-distance, heavy-load transportation (such as open-pit mines), but require the laying of power supply lines; battery-powered vehicles are ideal for short-distance, flexible operations (such as underground tunnels), but require regular battery replacement.

Q3: How is the safety of new energy equipment in the well ensured?
A: All new energy equipment from Ming Shun Machinery has passed explosion-proof certification. The battery packs feature independent encapsulation design, equipped with temperature sensors and automatic power-off devices to ensure stable operation in high-temperature and high-humidity environments.
