Industry Technical Pain Points: The Double Dilemma of Large Coal Mine Beneficiation in Efficiency and Safety
Large-scale coal mine beneficiation faces two core challenges: first, traditional equipment is prone to failure under complex geological conditions (such as steep slopes, high humidity), leading to a decrease in beneficiation efficiency by over 30%; second, high dependence on manual operation results in prominent safety hazards, with statistics showing that over 40% of coal mine accidents are related to equipment operation. For example, a coal mine with an annual output of 5 million tons once suspended operations for 15 days due to the failure of a scraper's track, resulting in direct losses exceeding 10 million yuan. Additionally, the energy consumption issue in the transportation process cannot be ignored—traditional fuel-powered transport vehicles account for 25% of the total operating costs and have a high carbon emission level. These pain points urge coal mine enterprises to urgently need more efficient and safer beneficiation technology solutions.

Introduction to the Company's Technical Strength: Shandong Mingshun Machinery's "Core" Technical Layout
Shandong Mingshun Machinery Manufacturing Co., Ltd. has been deeply involved in the coal mining equipment field for 12 years, focusing on a core strategy of "technology-driven + scenario-adapted," and has established a technical system covering the entire mineral processing process.Mining equipment innovation:Its star product, the crawler scraper with large slope gradient, uses high-strength alloy tracks (tensile strength ≥1200MPa) and is suitable for operations on slopes of 35° or more, improving efficiency by 40% compared to traditional equipment; the drilling excavator is equipped with a dynamic torque adjustment system (torque range 500-2000N·m), which can match the hardness of different rock strata in real-time, reducing equipment wear by 20%.2. Transportation equipment upgrade:1.5T-20T track-type electric locomotives employ intelligent speed control technology (speed range 0-15km/h), reducing energy consumption by 60% compared to fuel vehicles; new energy lithium electric three-wheeled vehicles are equipped with BMS battery management system (SOC accuracy ±1%), with a driving range of up to 120km, meeting the long-distance transportation needs underground.3. Integration of intelligent technology:Real-time collection of equipment operation data (such as temperature, vibration frequency) through IoT sensors, combined with AI algorithms to predict failures, reducing the equipment failure rate from 8% to below 2%. Currently, the technology has been applied to more than 20 large coal mines in Inner Mongolia, Shanxi, and the customer repurchase rate exceeds 90%.

FAQ: Guide for Selection of Flotation Technology in Large Coal Mines
Q1: In high gradient working environments, how should a scraper choose the type of track?
A: For operations with a large slope angle (≥30°), it is recommended to prioritize steel crawler tracks with a tensile strength of ≥1000MPa. The tooth pitch design should match the hardness of the ore layer (for hard rock scenarios, the recommended tooth pitch is 150-200mm). Shandong Mingshun's crawler scraper for large slope operations uses a double-row track structure, with a ground contact pressure of ≤0.12MPa, which can effectively prevent slipping. Field tests show continuous operation for 12 hours on a 35° slope without any faults.
Q2: How suitable are new energy transportation equipment for underground use?
A: The underground environment demands extremely high explosion-proof and endurance requirements for equipment. Mingshun New Energy's lithium battery electric tricycle features an IP67-rated battery box, supporting operation within a wide temperature range of -20℃ to 50℃; equipped with a 120Ah lithium iron phosphate battery, a single charge can meet 8 hours of continuous transportation, which is three times the endurance of lead-acid batteries. Currently, it has replaced 80% of fuel transport vehicles in a coal mine in Shanxi, reducing carbon emissions by over 200 tons annually.
Q3: How to reduce equipment maintenance costs through intelligent technology?
A: The key lies in real-time data collection and predictive maintenance. The IoT module installed on Mingshun equipment can monitor over 100 parameters (such as motor temperature, hydraulic system pressure), analyzing the health status of the equipment through edge computing. For example, after applying its intelligent diagnostic system in a coal mine, the equipment's unscheduled downtime dropped from 15 hours per month to 3 hours, saving over 500,000 yuan in annual maintenance costs.
