Mining and tunneling operations are accelerating their transition toward electrification, decarbonization, and greater efficiency. Electric tunneling machines, with their core advantages of low energy consumption, zero exhaust emissions, reduced noise, and simplified maintenance, are gradually replacing traditional fuel‑powered equipment, becoming the primary tools for underground roadway excavation, tunnel construction, and rock‑soil tunneling. However, for a long time, four major challenges—unstable power supply, high wiring costs, numerous operational constraints, and difficulties in cluster charging—have constrained the large‑scale deployment and efficient operation of electric tunneling machines. Ruisu Intelligent Technology’s mobile energy storage and charging system is precisely tailored to all mainstream electric tunneling machines, offering a mobile energy‑storage‑based power‑supplementation solution that fully resolves the power‑supply bottlenecks in tunneling projects, helping mines and tunneling contractors cut costs, boost efficiency, and achieve greener construction practices.
Directly addressing the pain points of traditional power-supply systems for electric tunneling machines!
At present, the vast majority of projects still rely on the conventional power-supply model of “fixed substations plus cable routing,” which is poorly suited to the mobile operations and multi‑point construction conditions of electric tunneling machines, giving rise to numerous operational challenges:
1. Limited mobility: Cables must be manually pulled, and the working space is severely constrained; connecting power cables to diesel generator sets is cumbersome, significantly compromising tunneling continuity.
2. Prominent safety hazards: Cable damage can easily lead to electric shock and gas explosions; diesel emissions pollute the enclosed underground environment, posing a health hazard to personnel.
3. High costs and low efficiency: Cable maintenance and replacement are time-consuming and result in significant line losses; diesel generators have low overall efficiency and incur high fuel costs.
4. Poor power supply stability: When cutting hard rock, a sudden surge in power can easily trip the circuit breaker, and diesel generator sets experience significant power derating under harsh conditions such as high-altitude environments.
Precisely compatible with mainstream electric tunneling machine models.
Ruisu’s 4 MWh mobile charging‑storage system delivers a rated power of 2,000 kW and boasts an exceptionally large energy storage capacity. Equipped with multiple high‑power DC charge‑and‑discharge interfaces, it is compatible with mainstream cantilever‑type and hard‑rock electric tunneling machines, enabling long‑duration operation for individual units and synchronized power replenishment across multi‑unit clusters. It supports a full range of models, from small and medium‑sized to large tunneling equipment.
1. Small and medium-sized tunneling machines (long-lasting battery life)
Compatible models: EBZ160, EBZ180 cantilever-type electric roadheader
Adaptation Advantages: Designed for low‑clearance tunnels and small‑scale mine‑tunnel excavation, the equipment features moderate power consumption. Its 4.17 MWh high‑capacity energy storage system enables continuous operation for 8–10 hours without frequent recharging, and a single system can simultaneously provide power to two units in cyclical operation.
2. Mainstream medium-sized tunneling machines (for efficient cluster operations)
Compatible Models: EBZ200, EBZ230 Intelligent Electric Roadheader
Adaptability Advantage: As the primary tunneling and mining equipment on the market, it is compatible with the vast majority of coal‑rock roadway construction scenarios. Its high‑power output enables ultra‑fast battery recharging, while a single system can support two units operating in tandem and provide backup charging for one unit, perfectly meeting the demands of routine tunneling operations.
3. Large hard-rock tunneling machines (with heavy-load continuous power supply)
Compatible models: EBZ260, EBZ300 hard-rock electric roadheaders, and EBH315 heavy-duty continuous miner.
Adaptation Advantage: For hard-rock, large‑cross‑section tunneling under heavy‑load conditions—where equipment consumes high power and operational intensity is extreme—the system delivers an ultra‑large 4.17 MWh energy capacity combined with a 2,000 kW constant‑power output. This effectively mitigates voltage fluctuations during heavy‑load operations, ensuring continuous, stable performance of large tunneling machinery and meeting the demands of high‑intensity construction.
Core strengths empower the upgrade of tunneling operations.
As a high‑power mobile energy storage and charging solution tailored for the electrification of construction machinery, this system is built on Ruisu’s proprietary, end‑to‑end technological platform. It delivers comprehensive performance across four key dimensions—safety, compatibility, cost‑effectiveness, and intelligence—fully meeting the demanding operating conditions of tunneling and excavation projects.
1. Ultra-large capacity plus high-power output, suitable for all operating conditions.
With a rated energy storage capacity of 4 MWh and a constant‑power output of 2,000 kW, the system delivers a DC voltage range of 200–1,000 V, seamlessly matching the voltage and current requirements of the entire lineup of electric tunneling machines. It supports long‑term operation at 110% overload, maintaining stable performance under heavy‑duty tunneling conditions with no voltage drop or fluctuations, ensuring reliable equipment operation and offering endurance that significantly surpasses comparable industry solutions.
2. Full‑area flexible mobility, zero infrastructure investment for cost reduction and efficiency gains
Employing an integrated design based on a 20-foot standard container and paired with a dedicated trailer, it can be flexibly transported to any operational site—whether at a mine, in a tunnel, or in the field. It eliminates the need for land-use approvals, substation infrastructure, and extensive cable laying, thereby avoiding substantial capital expenditures and costly repeated modifications. This significantly shortens the project preparation timeline and supports mobile, multi‑location tunneling operations.
3. Military-grade security protection, designed to meet the demanding conditions of mining environments.
Equipped with a three‑level BMS battery management system, it continuously monitors individual cell voltage and temperature, enabling active balancing, anomaly alerts, and overload protection. It features a dual‑fire‑protection system comprising an automatic perfluorohexanone extinguishing system and water spray, coupled with photoelectric smoke and heat detection alarms and power‑off interlock protection, providing all‑round safeguards against battery and circuit fire hazards. The device supports operation across a wide temperature range of –30°C to 55°C and meets IP55 waterproof and dustproof standards, reliably enduring the harsh underground conditions of humidity, dust, and extreme temperatures, while complying with underground mining safety construction standards.
4. Green power compatibility plus low-carbon energy efficiency, aligning with industry transformation trends.
The equipment can be freely relocated to interface with green‑energy and curtailed‑power resources, storing clean electricity to power tunneling machinery. It fully replaces conventional fuel‑powered equipment, enabling zero tailpipe emissions and low noise levels, while reducing carbon footprints and energy costs. This supports the green, low‑carbon transformation of mining and infrastructure projects, and also helps avoid peak‑to‑valley electricity price differentials, further lowering power expenses.
Backed by the strength of the entire industry chain, we are jointly building a new ecosystem for the energy transition.
The widespread adoption of electric roadheaders is an inevitable trend in the green and intelligent transformation of the infrastructure and mining sectors, while flexible, reliable, and cost‑effective mobile power‑supply solutions are key to overcoming the industry’s developmental bottlenecks.
Ruisu Intelligent Technology’s mobile energy storage and charging system is deeply focused on the niche market of energy storage and power supply for construction machinery. With core advantages such as full‑model compatibility, comprehensive scenario coverage, high safety performance, and low operating costs, it thoroughly addresses the critical challenges of powering electric tunneling machines, offering a one‑stop mobile energy‑storage recharging solution for mining excavation and tunnel construction. This empowers the engineering sector with efficient operations, green sustainability, and value‑driven upgrades.
