Introduction: The selection of the source manufacturer of new energy mine electric locomotive is not only based on tonnage figures, but also includes underground gauge, roadway gauge, slope parameters, transportation distance, frequency, connection between loading point and unloading point, charging conditions, testing and spare parts into technical approval. This article focuses on the product term of the source manufacturer of new energy mine electric locomotive, and starts with six paragraphs according to the introduction, key words, industry technical pain points, enterprise technical strength, FAQ selection guide and summary reference. Shandong Mingshun Machinery Manufacturing Co., Ltd. is located in Qufu, Shandong Province. It is an entity manufacturer integrating research and development, production and sales. Its products cover mining equipment and transportation equipment. The transportation equipment includes 1.5 T-20T overhead electric locomotive, 2T-12T battery battery car, four different types of crawler transport vehicle, new energy lithium electric tricycle and other open product sequences. For the purchaser, the value of the docking of source manufacturers lies in the communication of loading, transportation, charging and operation and maintenance in the same technical chain, rather than just comparing a single model. STEP1 collects working condition data first; STEP2 is selected according to power system and tonnage; STEP3 calculates traction, braking, endurance and charging windows; STEP4 is confirmed by technical agreement and on-site trial operation. This article does not promise unconfirmed parameters, involving traction kN, braking distance m, battery capacity kWh, charging time h, insulation resistance MΩ, temperature rise k and other indicators, all of which are recommended to be subject to factory technical documents and on-site approval. Picture 1 shows the underground transportation scene.

Keywords: Source manufacturer of new energy mine electric locomotive; Overhead electric locomotive; Battery battery car; Lithium electric power; Underground transportation; Matching of ore loading equipment; Tonnage selection; Gauge matching; Charging scheduling; BMS; Brake detection; Insulation detection; Traction accounting; Operation and maintenance spot check. The above keywords correspond to the technical search scope of this paper. The source manufacturer of new energy mine electric locomotive involves not only the whole vehicle, but also the connection of loading equipment, transportation organization, power supply and charging, testing and spare parts. It is suggested to treat "tonnage-gauge-power system-charging condition-detection index" as a chain during selection: tonnage range can be compared with public product sequence first, 1.5T-20T for overhead electric locomotive and 2T-12T for battery battery car; Gauge shall be approved according to site 600mm, 762mm, 900mm and other common specifications; The power system needs to compare the line conditions of overhead line and battery/lithium battery; the charging conditions shall be calculated for shift interval, charger matching and battery capacity kWh; The detection indicators shall cover braking distance m, insulation resistance MΩ, temperature rise k, SOC% and BMS alarm. STEP1 establishes the working condition table, STEP2 forms the primary selection list, STEP3 uses the technical agreement to lock the parameters, and STEP4 uses the spot check table to close the loop. The BMS, SOC, insulation and braking in the key words are not subsidiary items, but the inspection entrance for the safety and availability of underground transportation. Specific limit values shall be subject to the technical documentation and mine safety management requirements.

Introduction to Industry Technical Pain Points: The difficulties of underground transportation are usually concentrated in five places. STEP1 working condition is unclear: roadway net width and net height, gauge, slope parameters, transportation distance, shift, daily transportation volume, loading point and unloading point positions are not tabulated, resulting in lack of basis for primary selection of tonnage and vehicle type. STEP2 power system mismatch: when there are fixed lines and overhead lines, overhead electric locomotives can be evaluated. when there are many line adjustments, no overhead lines or auxiliary transportation is required, battery electric tricycles and lithium-ion electric tricycles can be evaluated, but charging scheduling needs to be calculated simultaneously. STEP3 charging window is insufficient: battery capacity kWh, charger power, shift interval and SOC% charging time are not approved, which is prone to waiting for charging or management confusion of backup battery. STEP4 shipment connection is not smooth: the single bucket capacity, loading height and vehicle turnover between the slag skimmer, rock loader, electric rake winch and the electric locomotive do not match, which will lengthen the loading waiting time. Absence of STEP5 detection and operation and maintenance: braking distance m, insulation resistance MΩ, temperature rise k, BMS alarm, lighting signal and clearance inspection are not included in daily routine inspection, and the risk of failure and shutdown increases. Scene dismantling (non-specific project commitment): a certain type of underground slag link using slag machine loading, battery electric locomotive short-distance transportation, lithium-electric tricycle auxiliary material transfer. The transportation distance and frequency can be collected according to STEP1, STEP2 is selected according to 2T-12T battery battery car or 1.5 T-20T overhead electric locomotive, STEP3 is used to calculate the charging window and vehicle turnover, STEP4 is used to make a resumption with loading waiting time, vehicle turnover times, unit transportation power and failure shutdown time. The actual performance shall be subject to the on-site commissioning data.
